01Overview

POLYLLOP is a MIDI sequencer plugin from 510k that moves beyond simple step sequencing into polyphonic and polymetric territory. It gives each of its four lanes its own rhythm, pitch, length, hold and velocity. The developer builds it on the logic of its earlier sequencer SEQUND. POLYLLOP does not generate sound. It sends MIDI to synths or hardware, which makes it useful for arpeggios, chord layers and shifting rhythmic textures in a DAW.

03In depth

Polymetric Sequencing and Lane Control

Each of POLYLLOP's four lanes runs on its own step count, so the lanes drift in and out of phase. That is the core of its polyrhythmic approach. Every lane has an adjustable length and its own playback mode: Forward, Backward, Pendulum, Bi-directional, or Random.

Step Lock protects chosen steps from randomization and resets, so you can keep a pattern's anchor notes while the rest evolves. Randomization and density controls apply chance to notes, rhythms and dynamics, either per lane or globally.

Scales, Transpose and Live Use

Scale Quantization keeps output in key or lets you run fully chromatic. The developer includes custom user scales and root shift support. Real-time MIDI Transpose shifts sequences chromatically or by scale degree from incoming MIDI, which suits live playing and DAW automation.

Up to 12 patterns can sit in one preset, and MIDI notes switch between them. MIDI Advance Mode lets your keyboard or a clip drive the step progression. If your DAW does not record live MIDI from the plugin, you can export sequences to MIDI and drag them into the arrangement.
