A pattern editor, in the “style” of a Tracker, for the Korg Electribe 2’s (synth, sampler, hacktribe).


This is very much a WORK-IN-PROGRESS, not too much works right now, except for reading a pattern in from the E2.



  • Display partial pattern in tracker UI
  • Switch patterns in tracker UI using E2 dial
  • Display full pattern (all 64 steps)
  • Edit pattern notes in tracker UI using E2 controls
  • Send edited pattern back to E2
  • Edit pattern parts, osc, ifx etc in Tracker UI
  • Edit instrument patchs (samples?) in Tracker UI
  • Playback pattern(s) from Tracker state (without sending to E2)
  • more?
