Capabilities

Built for sound,
not for bloat.

Every module earns its place. No hidden menus, no wall of knobs — just the controls that shape your sound.

Osc

Dual oscillators

Two independent oscillators with continuous wave morphing — saw, square, triangle, and sine blend in real time.

Mod

Modulation matrix

A 12-slot matrix routes LFOs, envelopes, and velocity to any parameter — with a visual patch overview.

Built-in FX

Drive, chorus, and a characterful delay live in the signal path — zero extra plugins required.

MPE

MPE support

Full MIDI Polyphonic Expression — per-note pitch, timbre, and pressure for expressive, human performance.
