KeyPad MIDI Controller

Transform 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 favorite DAW.

Perfect for mobile producers, live performers, beat makers, and sound designers.

VIEW MODES

Switch between five layouts from the View menu:

Piano: a familiar 2-octave keyboard with height-based velocity.
Grid: Isomorphic: every row and column keeps the same interval, so chords and scales have one shape anywhere.
Grid: 2 Rows: a piano-style pair of rows, naturals below, sharps above.
Grid: Minor Thirds: columns step up by 3 semitones, rows move chromatically.
Grid: Big Piano: large naturals with quarter-size sharps.

Your view, layout, and root note persist across sessions.

SCALE MODE

Choose from 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, putting every note under your fingers.

On the piano, the keyboard keeps its familiar shape - the black and white pattern is how you find your place without looking. Rather than move notes around, out-of-scale keys dim and stop responding to touch, so only the keys in your key are labelled and playable. Wrong notes are simply out of reach. Switch back to Chromatic anytime for the full keyboard.

GRID EXPRESSION

Every grid layout includes a dedicated mod-wheel row. A vibrant gradient highlights roots and notes, optional labels show note names, and per-note MPE with pitch bend gives each finger independent control.

BUILT-IN SOUND ENGINE

Play sounds directly without any external app. Load SF2 SoundFonts with multi-preset selection, or import SFZ, WAV, and M4A samples. The low-CPU engine maps samples across the keyboard automatically, and sound files persist across sessions.

AFTERTOUCH & MPE EXPRESSION

Add expressive depth with four aftertouch modes. Mono AT applies uniform pressure across chords, Poly AT sends independent pressure per note, and XY MPE allocates per-note MIDI channels (2-16) with Y on CC74 and X on Pitch Bend. Remap aftertouch or mod wheel to any MIDI CC or Pitch Wheel. A green gradient on pressed keys shows pressure in real time.

CONNECT TO YOUR MAC

Control Logic Pro, Ableton Live, or any Mac music software from your iPad or iPhone. Connect wirelessly over your local network with Bonjour, or plug in via USB for a rock-solid, zero-latency link.

STANDALONE OR AUV3

Load KeyPad inside GarageBand, AUM, Cubasis, BeatMaker, Drambo, or any AUv3 host to play your instruments without switching apps, with settings saved in your project. Or run it standalone to drive hardware synths, route MIDI to other iOS apps, or control your Mac.

TOUCH-OPTIMIZED PERFORMANCE

Height-Based Velocity: Touch keys at different vertical positions for dynamic velocity, with three curves to shape the response.

XY Performance Pad: Control two parameters at once with multi-touch. Assign any MIDI CC to each axis for filter sweeps, effect morphing, or live sound manipulation.

Smart Layout: Scales to the window, keeping the full layout with controls and pads on iPhone, iPad, Split View, and AUv3 plugin.
