The complete P-lock synth interface with its sequencer, keyboard, oscillators, filters, envelopes and effects

01 / PARAMETER LOCKS

A sequencer that
also shapes sound.

Enable P-LOCK, select a step and turn a knob. The value is stored only on that step. The next step can have a different waveform, cutoff, envelope or effect level – without extra automation lanes.
