POLYLLOP

POLYLLOP by 510k is a four-voice polymetric MIDI sequencer that pushes beyond simple step sequencing. Each of its four independent lanes has its own gate, pitch, length, hold, and velocity controls, with adjustable step counts for evolving polyrhythms and shifting patterns. You get per-lane play modes like forward, backward, pendulum, and random, plus step lock, density control, and integrated randomization to shape patterns with precision. Real-time MIDI transpose, scale quantization, and a 12-pattern system make it great for live performance and quick variation. It outputs MIDI, so it drives soft synths and hardware without generating sound itself, and it works with all major DAWs. Export to MIDI and MIDI advance mode add flexibility. Ideal for producers sketching arpeggios, layering chords, or exploring generative textures, POLYLLOP suits anyone wanting deep, hands-on sequencing without slowing down creativity.
