PEACH Polymetric Arpeggiator (AU/VST)

PEACH – Polymetric Arpeggiator

PEACH takes arpeggiation far beyond the classic up/down cycle.
Instead of forcing every lane to share the same step length, PEACH lets you set independent lane lengths, turning simple chords into evolving, meter-shifting patterns.

It follows the same streamlined, effective design philosophy as our polymetric sequencers SEQUND and POLYLLOP: clear controls, immediate results, and deep creative potential. PEACH also pairs beautifully with them, opening up even more complex sequencing and arpeggiation possibilities when combined.

Whether you’re sketching ideas, experimenting, or performing live, PEACH gives you an organic, hands-on arpeggiation workflow unlike anything else.

Key Features

Polymetric Lanes — Each lane (Gate, Hold, Octave, Velocity, MIDI CC) has its own step count for shifting interplay.

Advanced Note Control — Define order, latch, octave range, gate length, swing, and step advance modes globally.

Scale Quantize — Snap to factory or custom scales, or leave chromatic for free exploration.

Creative Randomization — Dice buttons and step-locking give you instant variation with musical control.

Performance-Ready — Store up to 12 patterns per preset and switch them instantly via MIDI. Host-visible parameters can be mapped to a controller or automated directly in your DAW.

Expressive MIDI CC Lanes — Sequence up to three assignable MIDI parameters (e.g., filter cutoff, decay, resonance).

Built for Workflow — Undo/redo, preset management, and scalable lanes keep you moving smoothly and creatively.
