Ocarino
MIDI routing and clock
Connect your MIDI keyboards, desktop synths and audio interface to an iPad, iPhone or Mac, then route MIDI, sync clock, sequence and mix in Ocarino, ready to play live.
Ocarino works with USB, Bluetooth and network MIDI devices.1 Each device gets its own input channel and destination tracks, and any track can play an external synth on any MIDI channel. Ocarino can send MIDI clock as the master or follow an external clock. The MIDI monitor logs every message in and out, with filters for device and direction, and exports the log.
Sequencer
Write drums, bass and melodies in the step sequencer for the built-in sounds and for external synths, or record from a MIDI keyboard with quantization. Each track has seven scenes, A to G, and you can switch them while playing. Any track can be muted or soloed, and tap tempo sets the speed.
Mixer
Audio interface inputs come into the mixer as channels, next to the built-in sounds. Every channel takes effects, sends, buses and sidechain. On a multichannel audio interface, each channel can go to its own outputs.2
Instruments and plug-ins
The built-in synth has five engines: FM with 32 algorithms, subtractive, wavetable, granular and drums. A ladder filter, curve control on every envelope stage, LFOs and a modulation matrix shape the sound, and a manual is built in. You can also load third-party Audio Unit instruments and effects.3
Sampler
Record from the mic or import audio files, slice them evenly, by beat or by transient, and play the slices from the keys or the step grid. Ocarino also finds a sample's beats, bars, tempo and key.4
Chords
As you play, Ocarino shows the chord name, its notes, the inversion and the staff notation, and marks where the chord sits in the current key on the circle of fifths and the keyboard. Performance mode shows which key the music sounds in.
Apple Watch
On stage, Apple Watch controls playback, sets the tempo with the Digital Crown and shows the current chord.5
