So, were you able to connect Launchpad mk1? I got one cheap, so I'm wondering if it can be done... I see that there is an input profile for it, so that part should work. But what's needed is a fixture definition, or whatever defines the "custom feedback" and what info is sent to it. In the programming manual for Launchpad mk1 is says that the way it interprets MIDI "note on" messages is this:
Bit Name Meaning
6 Must be 0.
5..4 Green Green LED brightness.
3 Clear If 1: clear the other buffer’s copy of this LED.
2 Copy If 1: write this LED data to both buffers.
Note: this behaviour overrides the Clear behaviour
when both bits are set.
1..0 Red Red LED brightness.
I think it's different than the Pro (as mk1 only has dual color LEDs, so colors are Green, Red and Amber-to-White. Now, what should I do to make it work via custom feedback?
