Omni: Pocket Synth
Chords, Strums & MIDI Out
Free · In‑App Purchases
New AUv3 MIDI Processor, expanded ARP, Chord Automap to white keys, Chorus FX, larger text/accessibility controls and improved synth voice options and MIDI control.
Omni: Pocket Synth is a compact, touch-first instrument for creating chords, strums, arpeggios, pads, keys, and rhythmic musical ideas with an immediate performance workflow.
Play harmonic layouts directly from the screen, shape two independent pocket synth engines, add motion and effects, and send MIDI to other apps or hardware. Omni is designed to feel fast, musical, and expressive without turning into a complex workstation.
Features:
- Touch-based chord and strum performance.
- Chord Voice and Strum Voice with independent sound controls.
- Wavetable and subtractive / virtual analog voice engines with focused pocket controls.
- Hold / latch modes for Chord and Strum performance.
- Multiple strum modes including Standard, Extended, Pentatonic, Scale, and Chromatic Touchplates.
- Built-in ARP with musical patterns, rate, octaves, gate, and swing.
- Simple drum engine with kick and snare sequencing.
- Reverb, delay, vibrato, and autopan performance effects.
- Layout Editor for custom chord layouts.
- MIDI In for playing from external controllers.
- MIDI Out for controlling other apps, AUv3 instruments, or hardware synths.
- Hold / latch performance can also be used with MIDI Out.
- AUv3 Instrument support for hosts such as AUM.
- Independent Chord MIDI Out and Strum MIDI Out in AUv3 hosts.
- Preset Manager with factory and user presets.
Omni works both as a standalone app and as an AUv3 instrument. In AUv3 hosts, you can route Chord and Strum MIDI outputs separately, making it easy to control different instruments from one performance surface.
The free version includes the core playing experience. Omni Pro unlocks the full preset workflow, AUv3 support, advanced strum modes, Layout Editor, MIDI Out, and other creative tools.
