feat(faderpunk): add 14bit MIDI-CC/NRPN support#470
Open
Conversation
Output-side apps (cv2midi, lfo, lfo_plus, turing, clkturing, rndcvcc, panner) gain a MidiNrpn param that routes send_cc through the NRPN protocol when enabled. lfo and lfo_plus also have MidiOut moved to last position for consistency. Receive-side midi2cv switches from wait_for_message to wait_for_event so NRPN messages are handled transparently in CC mode — no toggle needed on the receive side.
Add ParamMidiNrpn bool switch rendered for Param::MidiNrpn, registered in AppParam and wired into getDefaultValue / getParamValue in utils.ts. Update ParamMidiCc max from 127 to 16383 to accommodate NRPN parameter numbers (14-bit range).

I don't have the hardware to test it but showMIDI is showing the right messages

This PR adds 14bit MIDI-CC/NRPN support to Faderpunk (e.g. for Elektron devices). NRPN Sending can be enabled on a per app basis (via the configurator). MIDI-receiving apps can decide how to deal with NRPN messages themselves.
