launchpad.py
A Novation Launchpad (and Midi Fighter) control suite for Python.
If you ever dreamed of using your Launchpad for completely other stuff than music: Welcome !-)
Compatible with most [tm] single board computers.
Watch a 6s video here.
Or take a look at that one.
What about the brand new Launchpad Pro support? Right!
Hey - and the Mac? Yep, that finally works too. Look \o/
Upcoming attraction: Launch Control XL.
Oh, don't let us forget the Dicer.
Older Launchpads might be documented here.
Did we mention Python 3 yet?
First Mk3 and X Launchpad code snippets running now (4/2020).
Now with full Midi Fighter 64 support (8/2020).
Finally! Hehe, say hello to the Mk3 Pro (8/2020)
STATUS 2021/01/xx:
Devices
Launchpad Mk1 - class "Launchpad()" LEDs and buttons Launchpad/S - class "Launchpad()" LEDs and buttons Launchpad Mini - class "Launchpad()" LEDs and buttonsLaunchpad Mk2 - class "LaunchpadMk2()" LEDs and buttons
Launchpad Pro - class "LaunchpadPro()" LEDs and buttons (digitally only (yet))
Launchpad Pro Mk3 - class "LaunchpadProMk3()" EXPERIMENTAL+++ as in "should be really ok"
Launchpad Mini Mk3 - class "LaunchpadMiniMk3()" LEDs and buttons * RENAMED 5/2020 *
Launchpad X - class "LaunchpadLPX()" EXPERIMENTAL+++ as in "should work really well"
Launch Control - class "LaunchControl()" EXPERIMENTAL
Launch Control XL - class "LaunchControlXL()" LEDs, buttons and potentiometers
LaunchKey (Mini) - class "LaunchKeyMini()" Buttons, keys and potentiometers/sliders, no LEDs
Dicer - class "Dicer()" LEDs and buttons
Midi Fighter 64 - class "MidiFighter64" LEDs and buttons
PRO MK3 USERS:
You need to disable the Launchpad's "Transmit Clock" in the MIDI settings!
See section "For Launchpad Pro Mk3 users"The Pro Mk3 needs the latest Firmware to operate flawlessly. FW is only available
via a Novation account- and product registration.
Please notice that the class "LaunchpadMk3()" was renamed to "LaunchpadMiniMk3()" in 5/2020.
This was necessary to avoid confusion with the device search string and the new "Pro-Mk3" Launchpad.
The "Pro Mk3" now is in LaunchpadProMk3().
Please notice the changes in methods "Open()" and "Check()" for the Mini Mk3 and X.
Also, see demo files "hello.py" or "launchpad_rgb.py" as a reference on how to use them.
Python
Now with Python 3 support \o/
OS
Now full functionality also on Windows 10 and macOS based systems.
Successfully tested with Ubuntu 18.04-LTS+. Requires compiling your own PyGame though (which is actually very easy; see below...).

- added Pro ButtonStateRaw(); first *damn fast* button reads \o/
CHANGES 2016/01/10:
- The current version does not work with Mac OS X. Regarding that, as well as the fact that PyGame somehow reached its end of life, I am currently looking for other Midi libraries or implementations. - I bought a Launchpad Pro. Time to implement this, although I am not sure what will come first, building a new Midi system or implementing the Pro.
CHANGES 2015/02/21:
- Support for multiple Launchpads now finally built in. Use 'em all:
lp1 = launchpad.Launchpad()
lp2 = launchpad.Launchpad()
lp1.Open(0)
lp2.Open(1)
CHANGES 2015/02/18:
- Added option to select a Launchpad if more than one is attached. Also supports search for a device string, e.g. "Mini". - Added optional parameters and to Open()
Upcoming attractions, notes and thoughts
- "PK3": the Pro Mk3 has some issues; needs to be fixed
- "All": optionally avoid resetting the X and Pro Mk3 to Live mode in Close(); (bc LEDs turn on)
- "FNT": fix character set; e.g. "!", "0", "N" and probably many more
- "All": RGB to color code approximation (for flash/pulse and color code methods)

- "All": custom bitmaps and graphics
- "All": event system
- "All": better custom font support
- "All": [r,g,b] lists for colors, instead of single args (might affect compatibility)
- ...
cancelled:
- "M64": RGB to color code mapping NOPE This does not work.
Installation/Usage
Install as Python package
Via pip from PyPI
Please notice that the PyPI version is not always up to date!
Simply execute
pip install launchpad_py
or
sudo pip install launchpad_py
(in case you need superuser rights) to install it.
Notice that the required dependencies (see below) are not automatically resolved and you need to install PyGame separately.
Also make sure that you're using the right "pip", matching your Python 2 or 3 preference.
Check with
pip --version
Which should bring up somewthing like:
pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7)
For explicitly installing this in an Python 3 environment, use
pip3 install launchpad_py
From local file system
If you downloaded the Launchpad.py source package, simply execute the command
python setup.py install
from the base directory or
sudo python setup.py install
if superuser access is required.
Load and use the module with
import launchpad_py ... ... # Mk1 Launchpad: lp = launchpad_py.Launchpad() # Mk2 Launchpad: lp = launchpad_py.LaunchpadMk2() # Mk3 Launchpad: lp = launchpad_py.LaunchpadMk2() # X Launchpad: lp = launchpad_py.LaunchpadLPX() # Pro Launchpad: lp = launchpad_py.LaunchpadPro() # Pro Mk3 Launchpad: lp = launchpad_py.LaunchpadProMk3() # Control: lp = launchpad_py.LaunchControl() # Control XL: lp = launchpad_py.LaunchControlXL() # LaunchKey Mini: lp = launchpad_py.LaunchKeyMini() # Dicer: lp = launchpad_py.Dicer()
or if you dislike typing that much, use
import launchpad_py as lppy ... ... lp = lppy.Launchpad() lp = lppy.LaunchpadMk2() lp = lppy.LaunchpadMiniMk3() lp = lppy.LaunchpadLPX() lp = lppy.LaunchpadPro() lp = lppy.LaunchpadProMk3() lp = lppy.LaunchControl() lp = lppy.LaunchControlXL() lp = lppy.LaunchKeyMini() lp = lppy.Dicer()
For compatibility with existing code, use
import launchpad_py as launchpad
Install directly from Github
Instead of downloading the source distribution, you can directly install it from Github by executing
pip install git+https://github.com/FMMT666/launchpad.py
Via your system's package manager, e.g. on Raspbian
ATTENTION Raspberry Pi Raspbian user. This is for you!
Some Linux distributions come with their own PyGame package.
Check your manual :)
With "apt", for example, you could either try
apt search pygame
or
apt-cache search pygame apt-cache search pygame | grep pygame
Make sure to install the right PyGame version, matching your Python 2 or 3 prefewrence.
Sample output from a Raspbian Jesse:
python-pygame - SDL bindings for games development in Python (Python 2) python3-pygame - SDL bindings for games development in Python (Python 3)
An Ubuntu 17.0.1, which comes with Python 3 as default, outputs
python-pygame - SDL bindings for games development in Python python-pygame-sdl2 - reimplementation of the Pygame API using SDL2
but this is only a Python 2 installation of PyGame.
Direct usage
If you don't want to or cannot install the package on your system, simply copy the two files
launchpad.py charset.py
to your working directory.
Use those files as described above, but without the "_py":
import launchpad ... ... # Mk1 Launchpad: lp = launchpad.Launchpad() ...
or
import launchpad as LP ... ... lp = LP.Launchpad() ...
Universal loading template code
Checks for an installed version first, loads local one as the last resort
import systry: import launchpad_py as launchpad except ImportError: try: import launchpad except ImportError: sys.exit("error loading lauchpad.py")
Checks for a local version first (file in same folder), uses the installed one secondary
import systry: import launchpad as launchpad except ImportError: try: import launchpad_py except ImportError: sys.exit("error loading lauchpad.py")

Requirements
Some Pygame versions do not work on some OSes (e.g. v1.9.2 might cause trouble
with Windows 7/10). I cannot tell you any more than just "try!".
The latest fixes (4/2017) were tested with v1.9.3 (via pip from Python 2.7.13)
and Windows 10 (x64). That seems to work fine again...
As of 2/2018, launchpad.py comes with Python 3 support.
Tested, so far:
- Windows 10, Python 3.6.4, PyGame 1.9.3 (via pip), MK2 Pad
- macOS Sierra, Python 3.6 (Macports), PyGame 1.9.3 (via pip), Pro Pad
- Raspbian Jessy, RPi3, Python 3.4.2, PyGame 1.9.2a0 (via apt), Mini Pad
Python 3 might not (yet and out-of-the-box) work for:
- stock Ubuntu 16.04.3-LTS (requires building PyGame from sources)
- stock Ubuntu 17.04 (same)
- stock Ubuntu 17.10 (same)
- stock Ubuntu 18.04 (workaround available)
See below for instructions on how to compile PyGame on your own...
Previously, launchpad.py was tested under
- Linux, 32 bit, 64 bit
- Windows XP, 32 bit
- Windows 7, 32 bit, 64 bit
- Windows 10, 64 bit
- macOS Sierra
- Raspberry-Pi 1/2/3
- Beagle Bone (Black)
- Banana Pi (Pro/M2/R1)
- pcDuino V3
- ...
Supported and tested red/green LED Launchpad devices, here referred to as "Classic" or "Mk1":
- Launchpad (the original, old "Mk1")
- Launchpad S
- Launchpad Mini (Mk1)
Supported and tested full RGB Launchpad devices:
- Launchpad Pro
- Launchpad Pro Mk3
- Launchpad Mk2
- Launchpad Mini Mk3
- Launchpad LPX
Supported completely different stuff:
- Launch Control
- Launch Control XL
- LaunchKey (Mini)
- Dicer
- Midi Fighter 64
Notice that Novation now (1/2016) sells an RGB Launchpad under the same name it once shipped the first red/green LED with!
Compiling your own PyGame
If you have problems with errors like "alsa.conf" or the ListAll() method not recognizing any attached Launchpads on newer systems, especially Ubuntu 17/18, you might consider compiling your own PyGame version.
This explanation is for Ubuntu 18.04-LTS and Python 3, but it should work [tm] for most other systems too.
Additional package requirements, install them with
sudo apt-get install
I recommend installing these one after another (for easy "debugging")
git automake cmake libsdl1.2-devCompile via "setup.py"
Find the complete compilation instructions here.
Download the PyGame source code.
Notice that this will create a sub-folder named "pygame":git clone https://github.com/pygame/pygameEnter that directory and type
python3 setup.py buildwhich results in something like:
... No package 'freetype2' found WARNING: "pkg-config freetype2" failed! SDL : found 1.2.15 FONT : not found IMAGE : not found MIXER : not found PNG : found JPEG : not found SCRAP : found PORTMIDI: found PORTTIME: found FREETYPE: not foundWarning, some of the pygame dependencies were not found. Pygame can still compile and install, but games that depend on those missing dependencies will not run. Would you like to continue the configuration? [Y/n]
If you need a fully working PyGame, with all features, I leave it up to you, to resolve the remaining "not found" issues, but they're not required by Launchpad.py
Make sure PORTMIDI and PORTTIME are marked with "found", then continue the build process. After a hopfully error-free build, execute (Ubuntu example for superuser access)
sudo python3 setup.py installAfter a short time, you now should have PyGame in the default path
/usr/local/lib/python3.6/dist-packages/...
Compile via "configure" (old)
Newer Python variants come with a fully functional setup.py (see above).
I just leave the old compiling instructions here...Download the PyGame source code.
Notice that this will create a sub-folder named "pygame":git clone https://github.com/pygame/pygameEnter that directory and type
./configurewhich results in something like:
... No package 'freetype2' found WARNING: "pkg-config freetype2" failed! SDL : found 1.2.15 FONT : not found IMAGE : not found MIXER : not found PNG : found JPEG : not found SCRAP : found PORTMIDI: found PORTTIME: found FREETYPE: not foundIf you need a fully working PyGame, with all features, I leave it up to you, to resolve the remaining "not found" issues, but they're not required by Launchpad.py
Next, type
maketo create the build files, followed by a
sudo python3 setup.py installAfter a short time, you now should have PyGame in the default path
/usr/local/lib/python3.6/dist-packages/...
Random Notes
Button, value and potentiometer polling
Until now (6/2017), Launchpad.py does not have an event system built in. You need to poll the buttons' or potentiometer's values manually.
Notice that actually nothing will get lost, but every event you create will be buffered (until you run out or memory :). If you don't poll the buttons or potentiometers regulary, your might end up with thousands of old states and values, blocking the current input.
Especially rotating a potentiometer or pushing a slider, creates an event for each single value that was sampled. This can easily be hundreds of messages in a few seconds.So either poll regulary or use the ButtonFlush()/InputFlush() method to clear everything.
Also notice that the buffer might be filled right after you started your application...
For Launchpad Mk1 users (the original "Classic" Launchpad):
USE CLASS "Launchpad":lp = launchpad.Launchpad()For Launchpad Pro users
USE CLASS "LaunchpadPro":lp = launchpad.LaunchpadPro()As of 2016/01/24, the "Pro" is now automatically set to "Ableton Live mode", which is required for launchpad.py to work.
For Launchpad Pro Mk3 users
USE CLASS "LaunchpadProMk3":lp = launchpad.LaunchpadProMk3()You need to disable the "Transmit Clock" in the Launchpad settings! Hold "Setup" and disable the 2nd LED from the left (must be red).
Otherwise the receive buffer will be spammed with messages.For Launchpad Mk2 users
USE CLASS "LaunchpadMk2":lp = launchpad.LaunchpadMk2()For Launchpad Mini Mk3 users
USE CLASS "LaunchpadMiniMk3":lp = launchpad.LaunchpadMiniMk3()For Launchpad X users
USE CLASS "LaunchpadLPX":lp = launchpad.LaunchpadLPX()For Launch Control users
USE CLASS "LaunchControl":lp = launchpad.LaunchControl()For Launch Control XL users
USE CLASS "LaunchControlXL":lp = launchpad.LaunchControlXL()For LaunchKey (Mini) users
Even it is named "Mini", it also supports most of the bigger keyboards' functionalities.
Notice that some of the button and key numbers collide and cannot be differed.USE CLASS "LaunchKeyMini":lp = launchpad.LaunchKeyMini()For Dicer users
USE CLASS "Dicer":lp = launchpad.Dicer()The Dicer uses "page" mode by default. The three small buttons "cue", "loop" and "auto loop" select six different pages (per Dicer module) and each of those can be handled independently.
The first set of the six mode is enabled by simply pushing (and releasing) on of the three mode buttons, the second set, "shift-mode" is activated by holding down one of the mode buttons while pushing a number button.
So, if the "cue" page is active and you try to activate an LED in the "loop" page, that will not be visible until you activate that page.
For Midi Fighter 64 users
USE CLASS "MidiFighter64":lp = launchpad.MidiFighter64()The Midi Fighter needs to be set to MIDI channel 3 (factory default). It does not matter which bank is selected, both are supported.
Switching the banks does currently make no difference in button numbers or events. Drop me a note if it would make sense to change that ...
alsa.conf issues
Several users reported errors because of a missing alsa.conf file, e.g.:
ALSA lib conf.c:3009:(snd_config_update_r) Cannot access file /etc/alsa/alsa.conf ALSA lib seq.c:935:(snd_seq_open_noupdate) Unknown SEQ defaultIf /etc/alsa/alsa.conf does not exist, you can create a symbolic link to where it resides on your system. Find it with:
find /etc /usr -name "alsa.conf"If that command can not find "alsa.conf" (a common place is /usr/share/alsa/alsa.conf), you probably don't have Alsa installed at all.
In all other cases, you can create a symbolic link from /etc/alsa/alsa.conf to the real, existing file (assuming /usr/share/alsa/alsa.conf here).
Warning: Double check whether /etc/alsa/alsa.conf really does not exist first!sudo mkdir /etc/alsa sudo ln -s /usr/share/alsa/alsa.conf /etc/alsa/alsa.confAfter that, you still might experience that Launchpad.py cannot find any MIDI devices.
The output from "lp.ListAll()" does not return anything and executing the "hello.py" example just shows something like:Exception AttributeError: "'NoneType' object has no attribute 'quit'" in > ignoredIn this case, the default sequencer entries might be missing in your alsa.conf.
You might wish to add this to your alsa.conf:# # Sequencer interface #seq.default { type hw hint.description "Added by experts. Source: Internet \o/" }
seq.hw { type hw }
Thanks to MartinPaulEve for pointing that out.
Please notice that this "fix" won't work on all systems. While it does, for example, work with Ubuntu 17.04, the same error usually just indicates that your system was not built with a PyGame compatible ALSA (PortMidi) version.
There is no easy fix for this (unless you wish to spend a lot of time completely recompiling your system...)For Mac users
Mac Python and Pygame
Good news, everybody. It now works with macOS Sierra \o/
Best part: It even works with the stock "Apple Python".Pygame can be installed via "pip". Just enter "pip" on the console to see whether it is installed:
pipIf it isn't, you can install it with:
sudo easy_install pipIf pip is working, search for Pygame via pip (console command):
sudo pip search pygameSomewhere in the list, you should see something like
Pygame (1.9.2b8) - Python Game DevelopmentInstall that with:
sudo pip install pygameHardware
Notice that the original Launchpad Mk1 requires an USB driver. Thanks, Stewart!.
Get it from here (Novation USB Driver-2.7.dmg).As it seems, all newer Launchpads work right out of the box, no driver required.
For Raspberry Pi users
Please notice that some the newer RGB LED Launchpads consume more current than a Raspberry Pi can deliver. If you turn on a lot of LEDs, the Launchpad will just reset and show the fireworks demo.
At least for the Launchpad Pro, you could use an external power supply adapter. For the Mk2, you would need a an "USB-Y" cable, with the "power plug" connected to an external power supply (or other PC).As written somewhere above, at least for Raspbian (Jesse), you should install Raspbian's PyGame version via the package manager or apt. The PyPI version (installation via "pip") will not work due to some missing SDL components.
Btw, you can check your Raspbian version with the console command
cat /etc/os-releaseWhich outputs something comparable to
PRETTY_NAME="Raspbian GNU/Linux 8 (jessie)" NAME="Raspbian GNU/Linux" VERSION_ID="8" VERSION="8 (jessie)" ...For Windows users
MIDI implementation in PyGame 1.9.2+ is broken and running this might bring up an 'insufficient memory' error ( pygame.midi.Input() ).SOLUTION: use v1.9.1 or try v1.9.3
For Linux and especially Raspberry-Pi users:
Due to some bugs in PyGame's MIDI implementation, the buttons of the Launchpad Mk1 won't work after you restarted a program (LEDs are not affected).WORKAROUND #2: Simply hit one of the AUTOMAP keys (the topmost 8 buttons). For whatever reason, this makes the MIDI button events appearing again...
WORKAROUND #1: Pull the Launchpad's plug out and restart... (annoying).
Other Notes
Launchpad (Pro) not recognized, playing fireworks demo
Just discovered another oddity...
I attached a Launchpad Pro to my Linux box, as many times before, to finally add the button methods, but it refused to show up as an USB device. Instead of the "note mode", indicated by a turquoise/pink colour pattern, it played that "fireworks animation" and did nothing...
The first time I discovered that, I blamed it on an attached FTDI UART chip, but as it turned out, that was not the reason it didn't work.
It simply was a power issue.
So, if your Launchpad Pro shows that firework demo, check your USB cable!
Seriously. That thing draws a lot of current and most USB cables simply do not conform to the USB standard (or your USB port isn't, e.g. Raspberry Pi).On Linux, you can check that via the console command "dmesg".
If the output contains hundreds of "urb status -32" errors, followed by... [ 1414.983069] usb 1-1.5: urb status -32 [ 1414.983232] usb 1-1.5: urb status -32 [ 1414.983345] usb 1-1.5: urb status -32 [ 1414.983456] usb 1-1.5: urb status -32 [ 1414.983495] usb 1-1.5: USB disconnect, device number 8 [ 1414.983568] usb 1-1.5: urb status -32 [ 1414.983692] usb 1-1.5: urb status -32 [ 1415.288539] usb 1-1.5: new full-speed USB device number 9 using dwc_otg [ 1415.445968] usb 1-1.5: New USB device found, idVendor=1235, idProduct=0051 [ 1415.445984] usb 1-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 1415.445992] usb 1-1.5: Product: Launchpad Pro [ 1415.446000] usb 1-1.5: Manufacturer: Focusrite A.E. Ltd [ 1415.446009] usb 1-1.5: SerialNumber: Launchpad Pro ...My USB cable "looked quite good" from the outside.
With its ~5.5mm diameter, I assumed it had AWG 22 (~60mOhm/m) or better, but it in fact has ~drumroll~ AWG 28 (~240mOhm/m) and two thick plastic strings to fill the gaps.Well, we all know that companies try to save money wherever they can, but that's just fraud...
Btw, the fireworks demo will play whenever the Launchpad cannot be enumerated (configured).

Detailed description of common Launchpad methods
Open( [number], [name], [template (1)] )
Opens the a Launchpad and initializes it. Please notice that some devices have multiple and even up to six MIDI entries!To open the first Mini Mk3 or X device, "number" needs to be set to "1", not "0", as valid for (most) of the other Launchpads.
Some Launchpads, e.g. the "Mk3 Pro" come with 3 MIDI devices. While the first device's number is "0", the 2nd device will require opening number "3" and not "1".
(1) Notice that
As of 12/2016, the name search patterns are case insensitive, hence strings like "mk2", "pRo" or even "lAunCHpAd MiNI" are valid too.
Notice that the default name for the class Launchpad(), the "Mk1" or "Classic" Launchpads, will also react to an attached "Pro" or "Mk2" model. In that case, it's required to either enter the complete name (as shown by "ListAll()").EXAMPLES: # Open the first device attached: lp.Open()
# Open the 2nd Launchpad: lp.Open( 1 ) # Open the 3rd Launchpad Mini: lp.Open( 2, "Launchpad Mini") # alternative: lp.Open( name = "Launchpad Mini", number = 0) # open the 1st "Mk2" lp = launchpad.LaunchpadMk2() # notice the "Mk2" class! lp.Open() # equals Open( 0, "Mk2" ) # open the 1st "Mk3" # NOTICE: Mk3 has two MIDI instances and we need the 2nd one. # So, to open the first attached devices, use "Open(1)" and not "Open(0)". lp = launchpad.LaunchpadMiniMk3() # notice the "MiniMk3" class! lp.Open() # THIS WILL NOT WORK! lp.Open(1) # this will open the first device lp.Open(3) # this would open the 2nd attached Launchpad # open the 1st "X" # NOTICE: The X has two MIDI instances and we need the 2nd one. # So, to open the first attached devices, use "Open(1)" and not "Open(0)". lp = launchpad.LaunchpadLPX() # notice the "LPX" class! lp.Open() # THIS WILL NOT WORK! lp.Open(1) # this will open the first device lp.Open(3) # this would open the 2nd attached Launchpad # open the 1st "Pro" lp = launchpad.LaunchpadPro() # notice the "Pro" class! lp.Open() # equals Open( 0, "Launchpad Pro" ) # open the 1st "XL" with user template 3 lp = launchpad.LaunchControlXL( template = 3 ) lp.Open() # open the 1st "XL" with factory template 2 lp = launchpad.LaunchControlXL( template = 10 ) lp.Open()Check( [number], [name] )
Checks if a device is attached. Uses exactly the same notation as Open(), but only returns True or False, without opening anything.Like Open(), this method uses different default names for the different classes: Launchpad() -> "Launchpad" LaunchpadMk2() -> "Mk2" LaunchpadMiniMk3() -> "MiniMk3" LaunchpadLPX() -> "LPX" and "Launchpad X" LaunchpadPro() -> "Launchpad Pro" LaunchpadProMk3() -> "ProMk3" LaunchControl() -> "Control MIDI" LaunchControlXL() -> "Control XL" LaunchKeyMini() -> "Launchkey"
Notice that the first Mk3 and the first X Launchpads need to be checked with "1", not "0".
Notice that it's absolutely safe to query for an "Pro" or "Mk2" from all classes, e.g.:
lp = lauchpad.Launchpad() # Launchpad "Mk1" or "Classic" class if lp.Check( 0, "Pro" ): # check for "Pro" lp = launchpad.LaunchpadPro() # "reload" the new class for the "Pro" lp.Open() # equals lp.Open( 0, "Launchpad Pro" )
As of 8/2020, the recommended way is to simply omit the name and trust the internal name search, though the above "name search variant" might be helpful in a pinch.
if launchpad.LaunchpadPro.Check( 0 ): # check for "Pro" lp = launchpad.LaunchpadPro() # "reload" the new class for the "Pro" lp.Open( 0 ) # equals lp.Open( 0, "Launchpad Pro" )
Search patterns are case insensitive.
PARAMS: see Open()
RETURN: True device exists False device does not exist
Close()
No effect for most devices, except for the "Pro Mk3" and "X". Resets these Launchpads to Live mode.PARAMS: RETURN:
ButtonFlush()
Flushes the Launchpads button buffer. If you do not poll the buttons frequently or even if your software is not running, the Launchpad will store each button event in its buffer. This function can be used to clear all button events.PARAMS: RETURN:
ListAll( searchString = '' )
Debug function. Prints a list of all detected MIDI devices and addresses. Can be called any time and does not even require an opened device. The optional parameter can be used to return a filtered set of device names only. By default, it is set to an empty string, which simply prints everything.PARAMS: [OPTIONAL] only devices containing this string will be considered RETURN:
EventRaw()
Debug function. Returns an unprocessed list of all MIDI events.PARAMS: RETURN: [] an empty list if nothing happened or this MIDI message: [[[ , , , ], ]]

EXAMPLES: # scroll a red 'A' from left to right for x in range( -8, 9 ): lp.LedCtrlChar( 'A', 3, 0, offsx = x ) time.wait( 100 )
LedCtrlString( string, red, green, direction = 0, waitms = 150 )
Scrolls across the Launchpad's main, 8x8 matrix. specify the color and intensity (0..3 each). determines the direction of scrolling. Dirty hack: , by default 150, delays the scrolling speed.WARNING: Too short times will overflow the Launchpad's buffer and mess up the screen.
For future compatibility, it is highly recommended to use and as a named arguments, e.g.:
lp.LedCtrlString( "Hello", 3,1, direction = -1, waitms = 100 )
PARAMS: a string to display; e.g.: 'Hello' red LED intensity 0..3 green LED intensity 0..3 -1 -> scroll right to left 0 -> do not scroll, just show the character 1 -> scroll left to right OPTIONAL: delay for scrolling speed, default 150 RETURN:

Detailed description of RGB Launchpad only methods
Applies to "Pro", "Pro Mk3", "Mk2", "Mini Mk3" and "LPX" unless otherwise noted.
LedSetMode( mode ) >>> PRO, MK3, LPX ONLY <<<
Sets the Launchpad's mode. For proper operation with launchpad.py, the "Pro" must be set to "Ableton Live" mode. There is no need to call this method as it is automatically executed within Open().PARAMS: 0 selects "Ableton Live mode" (what we need) 1 selects "Standalone mode" (power-up default) RETURN:
LedGetColorByName( name )
WORK IN PROGRESS! ONLY A FEW COLORS, SO FAR!Returns a color in the special Launchpad Pro color code format, derived from a color name, in the string . [...]
PARAMS: a name of a color in lower caps, "red", "green"... RETURN: number Launchpad Pro color code
EXAMPLES: colorRed = LP.LedGetColorByName( "red" )
Supported, so far: off, black, white, red, green
LedCtrlRaw( number, red, green, [blue] )
+++ NOTICE: +++ It is recommended to always call this with a "blue" parameter. +++ The compatibility mode will be removed soon.Controls an LED via its number and red, green and blue intensity values.
This method uses system-exclusive MIDI messages, which require 10 bytes to be sent for each message. For a faster version, hence less comfortable version, see LedCtrlRawByCode() below (though even sending 10 bytes is pretty fast on the Pro).
If is omitted, this method runs in "Mk1" compatibility mode, which only had red/green LEDs and intensities ranging from 0..3. In that mode, the input arguments are multiplied by 21, to map 0..3 to 0..63.
Notice that the "Pro" and "Mk2" have different LED number layouts. Please see tables, somewhere below.
Notice that even though the Mk3 and the X support 0..127 intensities, only 0..63 can be used here. The values will be scaled up, resulting in the same intensity. Technically speaking, 0..63 is shifted left to match 0..127 with the LSB being omitted.
PARAMS: number of the LED to control a number from 0..63 a number from 0..63 OPTIONAL, a number from 0..63 RETURN:
LedCtrlRawByCode( number, [colorcode] )
Controls an LED via its number and color code. If is omitted, 'white' is used. This is about three times faster than the comfortable RGB method LedCtrlRaw().PARAMS: number of the LED to control a number from 0..127 (see image; white if omitted) RETURN:
LedCtrlPulseByCode( number, colorcode )
Controls an LED via its number and color code, as "LedCtrlRawByCode()" does, but pulsing the LED instead of just turning it on or off. If is omitted, 'white' is used. Pulsing can be turned off by simply sending another on/off command. The pulsing rate can be (roughly) set by LedCtrlBpm()Notice that there is no RGB control variant of this method (not supported by Launchpad).
PARAMS: number of the LED to control a number from 0..127 (see image) RETURN:
LedCtrlPulseXYByCode( x, y, colorcode, [mode] )
Pulses an LED via its x/y coordinates and color codes. An additional parameter determines the origin of the x-axis.For "Pro" only: By default, if is omitted, the origin of the x axis is the left side of the 8x8 matrix, like in the "Mk1" mode (those devices had no round buttons on the left). If is set to "pro" (string), x=0 will light up the round buttons on the left side. Please also see the table for X/Y modes somewhere at the end of this document.
PARAMS: x coordinate of the LED to control y coordinate of the LED to control a number from 0..127 (see image) OPTIONAL: "pro" selects new x/y origin >>> PRO ONLY <<< RETURN:
LedCtrlFlashByCode( number, colorcode )
Flashes an LED between two colors or on/off. The first color can be set by any "LedCtrl...()" command, the second color and the activation of the flashing is then done by this method. Flashing can be turned off by simply sending another on/off/color command. The flashing rate can be (roughly) set by LedCtrlBpm()Notice that there is no RGB control variant of this method (not supported by Launchpad).
PARAMS: number of the LED to control a number from 0..127 (see image) RETURN:
EXAMPLES: LP.LedCtrlRawByCode( 81, 16 ) # set top left LED (#81) to green ("16") (Mk2) LP.LedCtrlFlashByCode( 81, 6 ) # now set 2nd color to red ("6") and flash LED #81
LP.LedCtrlXY( 0, 1, 63, 63, 63 ) # set top left LED to white (Mk2) LP.LedCtrlFlashByCode( 81, 6 ) # now set 2nd color to red ("6") and flash LED #81LedCtrlFlashXYByCode( x, y, colorcode, [mode] )
Flashes an LED via its x/y coordinates and color codes. An additional parameter determines the origin of the x-axis.For "Pro" only: By default, if is omitted, the origin of the x axis is the left side of the 8x8 matrix, like in the "Mk1" mode (those devices had no round buttons on the left). If is set to "pro" (string), x=0 will light up the round buttons on the left side. Please also see the table for X/Y modes somewhere at the end of this document.
PARAMS: x coordinate of the LED to control y coordinate of the LED to control a number from 0..127 (see image) OPTIONAL: "pro" selects new x/y origin >>> PRO ONLY <<< RETURN:
LedCtrlBpm( bpm )
EXPERIMENTAL/PRELIMINARYSets the LED's pulsing or flashing frequency in beats per minute (bpm). By default, the Launchpads are set to 120 bpm.
Notice that this comes with several restrictions (yet):
This function blocks for 67.5 / bpm seconds, e.g.: 40 bpm - 1688 ms 100 bpm - 675 ms 240 bpm - 281 ms so it should only be called if absolutely necessary, preferably right in the beginning.
Due to the shortest time step of 1ms and the way the Launchpads handle the timing settings, the bpm values are restricted to:
10 ms - 250 bpm 23 ms - 108 bpm 36 ms - 69 bpm 49 ms - 51 bpm 11 ms - 227 bpm 24 ms - 104 bpm 37 ms - 67 bpm 50 ms - 50 bpm 12 ms - 208 bpm 25 ms - 100 bpm 38 ms - 65 bpm 51 ms - 49 bpm 13 ms - 192 bpm 26 ms - 96 bpm 39 ms - 64 bpm 52 ms - 48 bpm 14 ms - 178 bpm 27 ms - 92 bpm 40 ms - 62 bpm 53 ms - 47 bpm 15 ms - 166 bpm 28 ms - 89 bpm 41 ms - 60 bpm 54 ms - 46 bpm 16 ms - 156 bpm 29 ms - 86 bpm 42 ms - 59 bpm 55 ms - 45 bpm 17 ms - 147 bpm 30 ms - 83 bpm 43 ms - 58 bpm 56 ms - 44 bpm 18 ms - 138 bpm 31 ms - 80 bpm 44 ms - 56 bpm 57 ms - 43 bpm 19 ms - 131 bpm 32 ms - 78 bpm 45 ms - 55 bpm 58 ms - 43 bpm 20 ms - 125 bpm 33 ms - 75 bpm 46 ms - 54 bpm 59 ms - 42 bpm 21 ms - 119 bpm 34 ms - 73 bpm 47 ms - 53 bpm 60 ms - 41 bpm 22 ms - 113 bpm 35 ms - 71 bpm 48 ms - 52 bpm 61 ms - 40 bpm
PARAMS: beats per minute, 40..240 RETURN:
EXAMPLES:
LP.LedCtrlBpm( 100 ) # set LED flashing/pulsing to ~100 beats per minute
LedCtrlXY( x, y, red, green, [blue], [mode] )
+++ NOTICE:+++ It is recommended to always call this with a "blue" parameter. +++ The compatibility mode will be removed soon.
Controls an LED via its x/y coordinates and red, green or blue intensity values. An additional parameter determines the origin of the x-axis.
If is omitted, this method operates in "Mk1" compatibility mode. The Mk1 Launchpad only had 2 bit intensity values (0..3). In compatibility mode, these values are now multiplied by 21, to extend the range to 0..63. That way, old, existing code, written for the classic Launchpads does not need to be changed.
For "Pro" only: By default, if is omitted, the origin of the x axis is the left side of the 8x8 matrix, like in the "Mk1" mode (those devices had no round buttons on the left). If is set to "pro" (string), x=0 will light up the round buttons on the left side. Please also see the table for X/Y modes somewhere at the end of this document.
This method uses system-exclusive MIDI messages, which require 10 bytes to be sent for each message. For a faster version, hence less comfortable version, see LedCtrlXYByCode() below.
Notice that even though the Mk3 and the X support 0..127 intensities, only 0..63 can be used here. The values will be scaled up, resulting in the same intensity. Technically speaking, 0..63 is shifted left to match 0..127 with the LSB being omitted.
PARAMS: x coordinate of the LED to control y coordinate of the LED to control red LED intensity 0..63 (or 0..3 in "Mk1" mode) green LED intensity 0..63 (or 0..3 in "Mk1" mode) blue LED intensity 0..63 (omit for "Mk1" mode) OPTIONAL: "pro" selects new x/y origin >>> PRO ONLY <<< RETURN:
LedCtrlXYByCode( x, y, colorcode, [mode] )
Controls an LED via its x/y coordinates and a color from the color palette.Except for the color code, this function does the same as LedCtrlXY() does, but about 3 times faster.
PARAMS: x coordinate of the LED to control y coordinate of the LED to control a number from 0..127 OPTIONAL: "pro" selects new x/y origin >>> PRO ONLY <<< RETURN:
LedCtrlXYByRGB( x, y, colorlist, [mode] )
Controls an LED via its x/y coordinates and a list of colors in RGB format.This function does the same as LedCtrlXY() does, except that the color information is now passed in as list [R,G,B].
PARAMS: x coordinate of the LED to control y coordinate of the LED to control a list with [ R, G, B ] color codes; each from 0..63 OPTIONAL: "pro" selects new x/y origin >>> PRO ONLY <<< RETURN:
EXAMPLES: LP.LedCtrlXYByRGB( 3, 7, [63, 42, 0] )
LedCtrlChar( char, red, green, [blue], offsx = 0, offsy = 0 )
+++ NOTICE: +++ It is recommended to always call this with a "blue" parameter. +++ The compatibility mode will be removed soon.Sends character in colors (0..63 each) and lateral offset (-8..8) to the Launchpad. does not have yet any function.
It is highly recommended to use and as named parameters, for compatible code with the RGB Launchpads, e.g.:
lp.LedCtrlChar( 'a', 3, 2, offsx = xvar )
If is ommited, this methods runs in "Mk1" compatibility mode and multiplies the and intensity values with 21, to adapt the old 0..3 range to the new 0..63 one of the "Pro" mode. That way, it is compatible to old, existing "Mk1" code.
Notice that even though the Mk3 and the X support 0..127 intensities, only 0..63 can be used here. The values will be scaled up, resulting in the same intensity. Technically speaking, 0..63 is shifted left to match 0..127 with the LSB being omitted.
PARAMS: one field string to display; e.g.: 'A' red LED intensity 0..63 (or 0..3 in "Mk1" mode) green LED intensity 0..63 (or 0..3 in "Mk1" mode) blue LED intensity 0..63 (omit for "Mk1" mode) x offset of the character on the main, 8x8 matrix (-8..8) Negative is left and positive right. no function RETURN:

+++ NOTICE: +++ It is recommended to always call this with a "blue" parameter. +++ The compatibility mode will be removed soon (and the output on +++ Mk2 and Pro pads might be messed up).Notice that the Launchpad Pro has string scrolling capabilities built in, but this function provides the old, Mk1 compatible functionality. Advantages are custom fonts and symbols (in the future).
Scrolls a string across the Launchpad's main, 8x8 matrix. specify the color and intensity (0..63 each). determines the direction of scrolling. Dirty hack: , by default 150, delays the scrolling speed.
If is omitted, "Mk1" compatibility mode is turned on and the old 0..3 intensity values are strechted to 0..63.
For future compatibility, it is highly recommended to use and as a named arguments, e.g.:
lp.LedCtrlString( "Hello", 3,1, direction = -1, waitms = 100 )
Notice that even though the Mk3 and the X support 0..127 intensities, only 0..63 can be used here. The values will be scaled up, resulting in the same intensity. Technically speaking, 0..63 is shifted left to match 0..127 with the LSB being omitted.
PARAMS: a string to display; e.g.: 'Hello' red LED intensity 0..63 (or 0..3 in "Mk1" mode) green LED intensity 0..63 (or 0..3 in "Mk1" mode) green LED intensity 0..63 (omit for "Mk1" mode) -1 -> scroll right to left 0 -> do not scroll, just show the character 1 -> scroll left to right OPTIONAL: delay for scrolling speed, default 150 RETURN:
LedAllOn( [colorcode] )
Quickly sets all LEDs to the color code given by . If is omitted, 'white' is used.PARAMS: OPTIONAL, a number from 0..127 RETURN:
ButtonStateRaw( [returnPressure] )
Returns the state of the buttons and pressure events in RAW mode.Notice that this is not directly compatible with the "Mk1" ButtonStateRaw() method, which returns [ , ].
Only the Pro, X and Pro Mk3 support pressure events. They can be enables by passing "returnPressure=True" to the method call. Notice that the Pro and X behave differently:
Pro and Pro Mk3: There is only one pressure value for all buttons together. If multiple buttons are pressed, the biggest value is returned. There is no possibility to determine which button caused it. To distinguish the pressure events from button events, a fake
number of "255" is returned in the list: [ 255, ].X: The X supports multiple pressure values. For a distinction between button events and pressure events, "255" is added to the button number: [ 255 +

WORK IN PROGRESS
TemplateSet( template )
Activates one of the user or factory templates, as specified by
Reset()
Resets the Launchpad and (quickly) turns off all LEDs. Only resets the currently active template.PARAMS: RETURN:
LedGetColor( red, green )
Returns a the special Launchpad color coding format, calculated from a red and green intensity value.PARAMS: red LED intensity 0..3 green LED intensity 0..3 RETURN: number Launchpad color code
LedCtrlRaw( number, red, green )
Controls an LED via its number (see table somewhere below)PARAMS: number of the LED to control red LED intensity 0..3 green LED intensity 0..3 RETURN:

InputChanged()
Returns True if a button or potentiometer event occured. False otherwise.PARAMS: RETURN: True/False
InputFlush()
Flushes the Launch Control XL's input buffer. If you do not poll the buttons or potentiometer values frequently or even if your software is not running, the Launch Control XL will store each event in its buffer. This function can be used to clear all button and potentiometer events.PARAMS: RETURN:
InputStateRaw()
Returns the state of the buttons or the value of the last potentiometer change in RAW mode.In case the last event was caused by a button being pressed or released, this function returns the button number and either "True" or "False" or if a potentiometer was rotated or a slider moved, its value (0..127).
Notice that this is different from other's Launchpad "ButtonStateRaw()" methods, as it forces you to check whether the 2nd field is a number or a boolean value.
Notice that the Control XL buttons do not support an analog velocity value. For compatibility, either "0" or "127" are returned in the third list field, corresponding to "False" (0) or "True" (127).
PARAMS: RETURN: [ ] An empty list if no event occured, otherwise either [ , , 0/127 ] the button number, True or False and the velocity [ , , 0 ] the potentiometer number and its value 0..127 and are the RAW button or potentiometer numbers, the second field either determines the state of the button ("True" if pressed, "False" if released) or returns the value of the potentiometer that was changed.
EXAMPLES:
xlEvent = lp.InputStateRaw() if xlEvent != []: if xlEvent[1] is True or xlEvent[1] is False: print( "Button ", xlEvent[0], xlEvent[1] ) else: print( "Potentiometer ", xlEvent[0], xlEvent[1] )

Detailed description of Dicer specific methods
Reset()
Resets the Dicer, (quickly) turns off all LEDs and restores the power-on defaults. Notice that an enabled light show will *not* be stopped.PARAMS: RETURN:
ModeSet( device, mode )
Enables on of the seven modes (or button and LED "pages") of the Dicer:0 cue 1 cue + shift 2 loop 3 loop + shift 4 auto loop 5 auto loop + shift 6 one page mode
See ButtonStateRaw(), LedCtrlRaw() or the Dicer's button and LED table at the end of this document to see how mode 0..5 work.
If the "one page mode" is enabled, the mode buttons themselves do not select a bank anymore, but return a value instead.
PARAMS: 0 = master, 1 = slave 0..6 as specifies above RETURN:
ButtonStateRaw()
Returns the state of the buttons in (an already nicely mapped :) RAW mode. The returned numbers of the buttons equal the labels on the Dicer's buttons, with the following extension (also see the LED/button mapping ASCII drawing somewhere below):The three mode buttons "cue", "loop" and "auto loop" act as a modifier and add the following numbers to the button value. For "shift" operation, continue to hold down one of the three mode buttons while pressing a number.
Master, "cue": 01 .. 05 +shift: 06 .. 10 Master, "loop": 11 .. 15 +shift: 16 .. 20 Master, "auto loop": 21 .. 25 +shift: 26 .. 30

Constants
LED Modes
The following constants can be used instead of using integer values for the LED modes.MODE_BRIGHT[0..15] instead of 18..33 for brightness MODE_TOGGLE[0..7] instead of 34..41 for toggling MODE_PULSE[0..7] instead of 42..49 for pulsing MODE_ANIM_SQUARE instead of 50 MODE_ANIM_CIRCLE instead of 51 MODE_ANIM_STAR instead of 52 MODE_ANIM_TRIANGLE instead of 53Some examples: lp.LedAllOn( 5, 18 ) becomes lp.LedAllOn( 5, lp.MODE_BRIGHT[0] ); LED RED BUT OFF lp.LedAllOn( 5, 33 ) becomes lp.LedAllOn( 5, lp.MODE_BRIGHT[15] ); LED RED FULLY ON lp.LedAllOn( 5, 33 ) becomes lp.LedAllOn( 5, lp.MODE_BRIGHT[15] ); LED RED FULLY ON
Accessing "out of bounds" list values will of course crash your app.

LedCtrlChar( char, color, [offsx = 0], [offsy = 0], [coloroff = 0] )
Displays character with a color of and a lateral offset of (-8..8) on the Midi Fighter. does not have yet any function. The optional parameter specifies the background color. Notice that it is not possible to set this to "black" or off as the Midi Fighter doesn't support this.Also notice that this method is not compatible with the Launchpad "RGB-calls", because the Midi Fighter also lacks RGB support. For 500 bucks. Lol :-)
