Beat Kitchen Harmonic Synth

A true AUv3 plugin — load it inside GarageBand, AUM, Cubasis, Loopy Pro, or any AUv3 host, or play it standalone. Additive synthesis across 400+ scales.

Beat Kitchen Harmonics 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.

A big thanks to Gavinski of Gavinski's Tutorials for his detailed feedback on the UI, and to Rolf and Fliiva, who helped pilot this into a full AUv3. Keep the suggestions coming — there's big stuff still planned.
