About this app

Beat Kitchen Harmonic Synth is an additive synthesizer you play by shaping the overtone series itself. Instead of filtering a fixed waveform, you open, fold, and re-excite the harmonics directly, and hear the tone change as you move.

Sculpt the partials by hand, route LFOs, envelopes, and velocity through a modulation matrix to almost anything, and watch the waveform and spectrum respond live as you play. It all runs on the device, with no account and nothing uploaded.

For sound designers, producers, and anyone curious about where tone actually comes from.

What’s new

A big update, bringing everything since 1.3. A reworked Sculpt panel: per-partial pan editing shown as a bar from a centre detent, pan presets (Centre / Saw / Tri), and a Copy-to A/B picker. The Formant control slides the spectrum for vowel-like motion. Smoother touch editing throughout, and smoother Formant sweeps.
