The POLYLLOP Black Friday deal puts 54% off 510k's four-voice polymetric sequencer plugin, now $27 until Nov 12, 2026.
POLYLLOP builds on the logic of 510k's flagship sequencer SEQUND and pushes it into polyphonic, polymetric territory. It is made for people who want to get past simple step sequencing.
It does not make sound. POLYLLOP outputs MIDI, so it can drive soft synths and hardware alike.
You can sequence up to four independent voices, each with its own rhythm, melody, duration and velocity lanes. The maker pitches it for evolving arpeggios, layered chords and shifting textures.
Every lane can have a different step count. That is the polymeter part: lanes of unequal length drift against each other and produce long, evolving polyrhythms.
Playback is set per lane, with Forward, Backward, Pendulum, Bi-directional and two Random modes.
MIDI Advance Mode lets you drive the step progression from your MIDI keyboard or a clip, so the rhythm follows what you play. Transpose also has Scale-Dependent and Classic modes.
The maker says it works with all major DAWs and supplies routing instructions. The interface is kept minimal so you can stay on the pattern instead of the menus.
If live MIDI recording isn't supported in your host, export to MIDI lets you drag sequences straight into the DAW.
On Mac, POLYLLOP needs macOS 10.14 or higher, with Intel and Apple Silicon both supported (64-bit only). On Windows, it needs Windows 10 (64-bit only).
Activation uses a serial key, which needs an internet connection to validate, with occasional rechecks afterwards.
Yes. The POLYLLOP Black Friday deal takes 54% off, bringing the plugin to $27. The offer ends Nov 12, 2026. POLYLLOP is 510k's four-voice polymetric MIDI sequencer, built on the logic of its flagship sequencer SEQUND.
It is a MIDI sequencer plugin, not a synth. POLYLLOP generates no sound of its own and outputs MIDI instead. That lets you route it to soft synths in your DAW or to hardware instruments.
POLYLLOP runs up to four independent voices. Each has lanes for Gate, Pitch, Length, Hold and Velocity, with adjustable length and playback mode per lane. Step counts can differ between lanes, which creates the polymeter.
On Mac you need macOS 10.14 or higher, with Intel and Apple Silicon supported, 64-bit only. On Windows you need Windows 10, 64-bit only. An internet connection is required to validate the serial key at activation and in occasional rechecks.
