Novation Launchpad Pro

I’m interested in taking on writing a custom octatrack FW for the LP Pro. I have some experience programming cortex with C bootloaders so this should be a doddle, if a bit time consuming.

Has anyone been working on something similar? I can’t see any OT-specific github forks or anything from googling around, but perhaps someone here knows more.

What would you like to see? Keeping in mind the MIDI messages the OT will receive, and the fact that there is no permanent storage on the LP Pro.

Things I’m thinking of implementing:
Session: Combination of the trig button modes: 1-16 mutes, 1-16 track trigs, volume control
Note: rough clone of novation’s note mode. Chromatic trigs for tracks, 64 slice mode for tracks, chromatic entry for midi auto channel, highlights for selectable root note, scales. Assignable velocity/pressure > param for tracks. Momentary/toggle for notes.
Device: Every parameter on grid for tracks. push to assign value. 8-button ‘fader’ for coarse value, some combination for finer resolution.
User: Basic performance-focused sequencer. Have to see what I can squeeze into the memory, but hopefully some kind of motion recorder to quickly have the LP do midi param sweeps. Notes/velocity/pressure to auto channel.

Other things: dedicated pages for 8xVolume, 8xPan “faders”, keep Novation’s velocity > fade time, single button for sending param dump request to OT.

I’m working on something similar just in the sense that it’s an OT-oriented MIDI controller in C, but 1) I’m targeting the Raspberry Pi as a host and the LP Mini as the input/display so 2) I’m using the PortMIDI library and 3) I’m a C noob so 4) I’m going very slow and 5) my code is a mess. Also I haven’t thrown anything up on Github yet because of caveats #4 and #5

All of your ideas make a lot of sense and are similar to ones I’d like to implement, although I am shooting for something a bit more “modular” that probably won’t work well on the LP Pro. Slice mode will be huge - please see the thread for the wacky stuff you have to do to get this to work, if you haven’t already:

Triggering slices with midi notes?

I seem to remember someone saying that you could trigger the slices on the octa with certain midi notes, but I haven’t been able to find the specifics on this. Does anyone know which notes trig which slices, if at all possible?

Velocity/pressure to param is a fantastic idea. I don’t have an LP Pro but I want to try this with my old Trigger Finger at some point.

If you can, I would recommend implementing some kind of “snap shot” behavior. There was a guy working on this in Max before and I would also like to implement a version of this at some point. It might be weird on the LP Pro with no user-writable non-volatile memory but I think you might still be able to come up with something useful if you want to take a swing at implementing that.
