AUv3 on iPhone and iPad: how to use a synth plug-in in your host

What AUv3 is

AUv3 (Audio Unit v3) is Apple's audio plug-in format. An AUv3 app runs inside a host (DAW) on iPhone, iPad or Mac, as an instrument or effect — several at once, each on its own track.

Tonic as instrument and as filter

Tonic ships as two AUv3 plug-ins: an instrument (the full synthesizer) and an insert filter (to process other tracks). It also runs standalone, with an on-screen keyboard.

Step by step (e.g. AUM or GarageBand)

1. 1Install Tonic and open your host (AUM, Loopy Pro, GarageBand, Logic, Cubasis…).
2. 2Create an instrument track and pick "Tonic" from the Audio Units list.
3. 3Play with a MIDI keyboard or the host's keyboard.
4. 4To use it as an effect, add Tonic's AUv3 filter as an insert on an existing track.

MIDI and presets

Tonic responds to notes, pitch-bend and mod-wheel, and has MIDI Learn on any control. Presets are saved on the device. It is a one-time purchase, no subscription.
