Volna neon wave icon and feature summary

Built for performance

An instrument, not a piano roll.

Every part of the surface is playable. Move horizontally for pitch, vertically across registers, and use pressure or motion when the device exposes it.

01

Four synthesis engines

Volna Classic, YAWN Wavetable, YAWN Subtractive, and YAWN Karplus-Strong — including per-note pitch bend.

02

Multitouch surface

Up to ten fingers, one to eight color-coded registers, note callouts, and a full-surface scope with waveform and spectrum.

03

Microtonal by design

TET 2–48, custom TET12 scales, 24-TET presets, root and A4 tuning, octave stretch, and an optional pitch-bend depth.

04

Registers and chord layouts

Set 1–8 vertical registers in semitones or scale steps. Use octave, power, major, minor, and standard-guitar string presets.

05

Motion and touch modulation

Route accelerometer, gyro, magnetometer, Touch X/Y, and relative Touch ΔX/ΔY to synth and audio-effect destinations.

06

Loop, MIDI, and effects

Record a 60-second loop with seam crossfade, edit MIDI and audio chains, and connect MPE, Android MIDI, or RTP-MIDI.

Inside Volna

Play, tune, shape, modulate.

Engine controls, scale design, microtonal tuning, and a modulation matrix live alongside the performance surface.
