This is to be an openframeworks addon for the Teenage Engineering OP-1

##Current plan

To simplify full midi IO for the OP-1 with openframeworks


  • Rough graphical simulation of the OP-1
  • Midi input controlling encoders on screen
  • Midi input controlling control buttons on screen
  • Midi input controllong keyboard keys on screen (with octave correction when in CTRL mode)
  • On screen keyboard (controlled by mouse) giving midi output to OP-1
  • OP1 screen shows stereo visualisation
  • Midi data passed through a ofEvent listener


  • ofxMidi.h (and linking to the Core MIDI framework
  • ofEvents.h
You can’t perform that action at this time.
