Details: Each step triggers an oscillator and configures an array of effects. Pitch can keyboard controlled, and there is an added synthesizer in the sub view. Delay effect (1s tesmpo synced, 250ms, or 50ms). Sequencer speed set by tempo and beat/division. Each step has: Pitch control setting, pitch shift (octave, note, microtones) an oscillator with 7 waveform types, a waveshaper, a 4-pole filter, LFO with wave type, speed (tempo synced), depth, and offset.
