510k POLYLLOP v1.0.0-BUBBiX

510k POLYLLOP is a four-voice MIDI sequencer for producers who want moving arpeggios, layered chord parts and rhythms that change over time. It generates MIDI rather than audio, so you pair it with a software instrument or route it to hardware. This Windows version suits hobby producers looking to explore patterns beyond a conventional step grid.

Each voice offers separate Gate, Pitch, Length, Hold and Velocity lanes. Give lanes different step counts and playback directions to build overlapping cycles, or introduce variation with randomization and density controls. Step Lock keeps selected steps intact while you experiment with the rest.

Scale quantization, custom scales and MIDI-controlled transposition help you develop melodic ideas without rewriting every note. Store up to 12 patterns in a preset and trigger changes with MIDI notes, or use MIDI Advance Mode to control step progression from a keyboard or clip.

For arranging, drag sequences into your DAW as MIDI. POLYLLOP is useful for electronic music makers who enjoy generative variation but still want control over pitch, timing and dynamics.
