Your iPhone / iPad becomes a MIDI effects processor.
Create evolving patterns, generate musical variations and take control of your hardware synths with unprecedented power.
Chain up to 4 consecutive MIDI effect slots
Build your MIDI signal flow in the order you choose.
Chord Engine
Play one note, trigger a full diatonic chord — always within the scale of your choice.
Arpeggiator
Direction, note value (1/1 to 1/64), octaves, Gate, Swing, Latch and Transpose. Synced to internal or external clock.
MIDI Delay
Rhythmic MIDI repeats, synced or free-running. Feedback, decaying velocity and per-echo transposition for cascading melodies.
Harmonize
Automatic parallel voices on every note — third, fifth, octave — always anchored in the chosen scale.
Steper
16 polyphonic steps with note, velocity and duration. Patterns that layer on top of your real-time playing.
Patches & Presets
Save your entire chain — order, parameters, scale — and switch between presets in one tap, even live.
Chain, move, repeat.
Add up to 4 effect slots, move them, remove them freely. Each effect can also pass the original MIDI signal through in parallel.
Patches, saved. Recalled on the fly.
Each patch — full chain, effect order, parameters, scale — exports as a .json file : backup, sharing, restore in one tap. Live, each patch is mapped to a fixed Program Change (0 to 127) : any MIDI pedalboard or controller can recall your presets remotely, without touching the iPhone.
Export .json
Each patch saves to a .json file — backup, sharing between devices, restore anytime.
Fixed Program Change
Each patch corresponds to a Program Change number (0-127), received from any standard MIDI pedalboard or controller.
Per-effect presets
Each effect — Chord, Arpeggio, Delay, Harmonize, Steps — also saves its own presets, individually controllable via macro or MIDI CC.
Compatible with your whole setup.
MIDI USB
Connect your iPhone to your Mac via USB and enable the network MIDI session in Audio MIDI Setup. MidiDeep then appears as an external MIDI interface in your DAW — Ableton, Logic, GarageBand.
Bluetooth BLE
Pair MidiDeep directly to your computer or sequencer via low-latency Bluetooth LE. No cable, no driver — ideal in the studio and on stage.
MIDI DIN
With a simple USB-C to MIDI DIN adapter cable, turn your iPhone into a true standalone MIDI effects pedal — plugged directly between your keyboard and your hardware synth, no computer needed.
Inter-App MIDI
Chain MidiDeep with your other iOS apps via the inter-app MIDI session. In AUM, Audiobus or GarageBand, MidiDeep processes your notes in real time — right at the heart of your mobile workflow.
