A drawn waveform monosynth conceptually based on Mark Andrews' step oscillator. Simply draw your waveform using the sliders, create your envelope, and adjust the effects. Both warp and delay effects have handy XY based panels for live tweaking and automation.
Supports microtuning via MTS-ESP. Use a compatible MTS-ESP tuning master to explore alternative scales and tuning systems beyond standard 12-tone equal temperament.
