Tonic Synths

About this app

Tonic Synth puts a studio full of synthesizers in your pocket.

14 unique synths. All live. All real.

Draw sound with your finger on the XY pad. Twist an FM drone
into alien textures. Program an 8-step melody. Sculpt noise
through resonant filters. Drown everything in reverb.

Every control changes the sound instantly — no presets,
no menus, just your hands on the instrument.

Hear something you love? Hit record. You get 60 seconds.
Export it as a WAV file and take it anywhere — into your DAW,
your sample library, or share it straight from the app.
