ETCH at a glance

For ETCH 1.38 · checked against its source

A wavetable synth where you draw the waves yourself: morph wave A into B, let a third wave C bend the result, then add filter, 17 effects, arp with RIFF generator and a sequencer. Play a key and turn KNOB 1 (MORPH) first.

Good to know

  • Holding OCT- and OCT+ together for 5 seconds also jumps to the update loader: tap them together for POLY / MONO and let go.
  • Saving a preset does not save a newly drawn wave: save the wave first (EDIT, SAVE), then the preset.
  • 16 factory waves (SINE, SAW ... SCRATCH) and 32 presets to start from; a save needs a name (KNOB 3 picks letters).
  • EVOLUTION, ORGANIC, SPECTRAL, LIVING and PATCH BLEND only appear in MONO: tap OCT- and OCT+ together, then LFO.
  • Wave C does nothing at DEPTH 0: raise ETCH (KNOB 2 on PLAY) to hear it.
  • Experimental firmware: keep a stock firmware file at hand before installing.

A community cheat sheet by the hub, not by the firmware's makers: when in doubt, their manual is right.
