The LaunchPad X is not supported at the moment. There is a good chance that the MIDI messages are very similar and that we can get at least basic features just by adding it to the detection code. If you have a LaunchPad X and some Python skills, I'll be happy to walk you through the process!

Some details ...

The code detects the type of LaunchPad by looking at the MIDI port name.
Depending on the name of the port, it uses a different adapter class (because the exact MIDI messages change a bit between different models of LaunchPad).

The detection is done here:
https://github.com/jpetazzo/griode/blob/master/griode.py#L54

It should be relatively easy to add support for the LaunchPad X (assuming that the MIDI messages are not too different).

I have a Launchpad X, very little Python but lots of programming experience.

Just running grode and there is a port_name (in detected_ports) of Launchpad X:Launchpad X MIDI 2 24:1 and Launchpad X:Launchpad X MIDI 1 24:0

Added a class in launchpad.py by copying LaunchpadMK2 called LaunchpadX and edited griod.py until it ran.

The pad lights up and when I press a button that is not lit I get: [WARNING] launchpad.py:42 process_message() -> Unhandled message: note_on channel=0 note=49 velocity=0 time=0. If I press on green, blue or pink button I get nothing on the console.

No sound yet

Hi! You're definitely on the right track 👍

I downloaded the LaunchPad X programmer manual and compared it to the LaunchPad Pro programmer manual. Good news: the "programmer layout" of the LaunchPad X seems to be exactly the same note# and CC# than on the Pro!

However, the fact that you mention green/blue/pink means that the LaunchPad is probably still in its default layout (the "Note" layout), as opposed to the "Programmer layout" used by Griode on the LP Pro. Normally, when Griode starts, it sends a special MIDI sequence (a SysEx) to the LP Pro to switch modes automatically; then it "refreshes" the display, and at that point, the LaunchPad should show the default initial layout, which should be a C scale where C is in red, DEFGAB are in white, and the flats and sharps are in black. (This should all happen almost immediately when starting Griode.)

Here is what I would try.

  1. Change the code (as you did) but use the LP Pro class instead of the Mk2 class. (The Mk2 has slightly different MIDI messages for the top- and right- rows of pads.)

  2. Try switching to Programmer Mode using the LaunchPad's "setup" menu. (I'm not familiar with the LaunchPad X so I don't know exactly how that works; so if that doesn't make sense to you, let me know, and I'll check in the user manual :))

  3. Then, start Griode. If you're lucky, the LaunchPad will flash and show the C scale with C in red.

If that works, then I would add code in Griode to automatically send the SysEx to switch modes. That part should be relatively easy because there is already that behavior for the LP Pro, and the sequences are well documented in Novation's programmers manuals, so I would be able to help if needed.

Fantastic. It will be a few days before I get a chance to look closely at this again.

But in the meantime may I ask...

I see:
[INFO] fluidsynth.py:78 __init__() -> Using audio driver: jack

in the log from FluidSynth but not....

        # Invoke fluidsynth a first time to enumerate instruments
        logging.debug("Invoking fluidsynth to enumerate instruments...")

All there is between the two logging messages is:

        popen_args = [
            "fluidsynth", "-a", audio_driver,
            "-o", "synth.midi-bank-select=mma",
            "-o", "synth.sample-rate=44100",
            "-c", "8", "-p", "griode"
        ]

I know almost no Python, but I cannot see how that would fail

I downloaded the user manual. I cannot see how to get into set up

I changed the code as you suggested. Buttons green, blue and pink

Got sound!
Had to use qjackctl to connect fluidsynth to sound output.

Happy happy joy joy!

I found this in the doc:

To switch between Live Mode and Programmer Mode, enter the settings menu by pressing and holding Session briefly. Press the green Scene Launch button to enter Live Mode, or the orange Scene Launch button to enter Programmer Mode.

This is what I'd try to switch modes. Normally when switching modes the grid should go all black ... Then start Griode, and it should show the C scale with red octaves. Fingers crossed :-)

And congrats on qjackctl! I had missed that point in your message; but yes, I am not very familiar with Jack myself (I need to learn it, though) so I never know which extra steps are necessary ...

Only one of the Launchpad X's midis is connected to griode. But I kknow less about midi than I do about python

some pads are producing sound

This is the output of the griode command. If it wouldhelp next time I will turn up logging.

Update: I am also tryingouy r_cycle. I have issues with that too: Focusrite-Novation/r_cycle#1

20201127_NoteMode_II

Hi!

Sorry, for some reason I had missed the notification about your message above; I just saw your pull request (#17).

This looks like it works!

To understand the modes, scales, etc., perhaps this poster can help?

I'm going to take a look at your PR, and let me know if you have further questions meanwhile!
