Midi out for Jukebox mode

[streetuff]

Hi!

would be usefull, if a midi out mode could be implemented for the jukebox mode. That way i could control external devices like Roland MC-303, Behringer TD-8, Korg Volca NuBass, Roland TR6-S. Maybe make it switchable via a GPIO. External devices should probably only receive Note data and no CC-Messages, so you could tweak the potentiometers youself :)

all that's possible. for now there's a #define MIDI_RAMPS in config.h which turns off all CC automation when commented out. and you can attach potentiometers to the defined pins. There're 3 pots configured to play with the second 303 cutoff, reso and distortion. Midi output shouldn't be hard to code as well.

Yeah. Have seen your recent update. But i dont want to use POTs on the ESP, but on my synths :)
Could be super fun, to play the acidbanger on external synths.

I don't have either ESP32 or some synth by me right now, can you check if the next modification will result as expected:
Starting at line 297 of AcidBanger.ino, replace the two following functions with this :

static void send_midi_noteon(byte chan, byte note, byte vol) {
#ifdef MIDI_VIA_SERIAL  
  MIDI.sendNoteOn(note, vol, chan);
#endif
#ifdef MIDI_VIA_SERIAL2  
  MIDI2.sendNoteOn(note, vol, chan);
#endif
  handleNoteOn( chan, note, vol) ;
}

static void send_midi_noteoff(byte chan, byte note) {
#ifdef MIDI_VIA_SERIAL  
  MIDI.sendNoteOn(note, 0, chan);
#endif
#ifdef MIDI_VIA_SERIAL2  
  MIDI2.sendNoteOn(note, 0, chan);
#endif
  handleNoteOff( chan, note, 0) ;
}

I can confirm, that it is working. just tried with the behringer TD-3, Volca NuBass and the Roland TR6-S. Very cool!

Nice. That is cool.

Hi there. Is it correct that above had been committed (5b9e5b9) and doesn't need adding to AcidBanger.ino any longer? Thanks

Yes, noteOn and noteOff are sent to the active midi ports. Just check config.h to select appropriate port(s).
