Switches

OSCA WAVE = MIDICC 62 OSCB WAVE = MIDICC 63 OSCB ENABLE = MIDICC 64 OSCA NOISE = MIDICC 65 OSCB OCTAVE = MIDICC 66 LFOWAVE = MIDICC 67 LFOMODE = MIDICC 68 LFODEST = MIDICC 69 LFOKEYSYNC = MIDICC 70 DISTORTION = MIDICC 71 DCFTRACK = MIDICC 72 DCFMODE = MIDICC 73 MODWHEEL = MIDICC 74

switch values are read such that 0-127 is "off" and 128-255 is "on".


A quick look at Pd

• Understanding patching

• midiin, midiout

• notein, noteout, makenout
