Turn your iPad or iPhone into a professional MIDI controller with a touch-optimized piano keyboard, isomorphic grid, drum pads and XY performance controls. Control iOS apps, hardware synths and Mac software wirelessly or wired, as a standalone app or an AUv3 plugin in your DAW.
Five layouts from the View menu: Piano, Isomorphic grid, 2 Rows, Minor Thirds and Big Piano.
Isomorphic grid keeps the same interval in every row and column, so chords and scales have one shape anywhere.
2 Rows lays out naturals below and sharps above, Minor Thirds steps columns by 3 semitones, and Big Piano pairs large naturals with quarter-size sharps.
Piano keyboard with adjustable key width and PPI-based real-size rendering. View, layout and root note persist across sessions.
Scale mode
12 scales (Major, Natural Minor, Harmonic Minor, Melodic Minor, Dorian, Phrygian, Lydian, Mixolydian, Locrian, Pentatonic Major, Pentatonic Minor, Blues and Whole Tone) in any of the 12 root keys.
On the grid, cells remap so only in-scale notes are laid out, with no dead keys in between.
On the piano, the keyboard keeps its familiar shape, but out-of-scale keys dim and stop responding to touch, so only the keys in your key are labelled and playable. Switch back to Chromatic anytime.
Sound engine
Built-in sound engine plays SF2 SoundFonts with multi-preset selection, SFZ instruments, Bliss ZBP presets and ZBB banks, plus WAV and M4A samples, with no external app needed.
The low-CPU engine maps samples across the keyboard automatically, and sound files persist across sessions.
Expression
Aftertouch and MPE expression modes: Mono AT for uniform pressure across chords, Poly AT for independent pressure per note, and XY MPE with per-note MIDI channels (2-16), Y on CC74 and X on Pitch Bend.
Remap aftertouch or mod wheel to any MIDI CC or Pitch Bend, with a green gradient on pressed keys showing pressure in real time.
Every grid layout includes a dedicated mod-wheel row, with optional note-name labels and per-note MPE pitch bend.
Performance
Height-based velocity. Touch keys at different vertical positions for dynamic response, with linear, exponential and logarithmic curves.
XY performance pad controls two parameters at once with multi-touch, with any MIDI CC assignable to each axis.
Velocity, Pitch Bend and Modulation faders drawn as shaded rotating cylinders, plus a latching sustain button and a 9-pad drum grid for finger drumming.
Smart layout adapts to device orientation and size, with a full layout on iPad and a compact keyboard-only mode on iPhone or Split View.
Connectivity
AUv3 plugin for GarageBand, AUM, Cubasis, BeatMaker and Drambo, with settings saved in your project.
Control Logic Pro, Ableton Live or any Mac software wirelessly with Network Session MIDI and Bluetooth MIDI, or wired via Inter-Device MIDI for a zero-latency link.
MIDI In and Out channel and device selection, so you can mute a controller sending unwanted data without unplugging it.
OSC (Open Sound Control) output, 16 MIDI channels plus Omni mode, and a virtual MIDI port that never feeds its own output back in.
