  • ADSR envelope

Operation

screenshot

  • ENC1 adjusts main output level.
  • ENC2 changes filter cutoff.
  • ENC3 changes filter resonance.
  • KEY2 momentary toggles fine parameter control.
  • KEY3 triggers a random note.
  • MIDI device plays notes.
  • GRID plays notes too.
  • ARC changes filter cutoff (ENC1) and filter resonance (ENC2).
