KeyPad MIDI Controller

Transform your iPad or iPhone into a professional MIDI controller with touch-optimized piano keyboard, isomorphic grid, drum pads, and XY performance controls. Control iOS apps, hardware synths, and Mac software wirelessly via Network Session MIDI, wired via Inter-Device MIDI, or route between iOS apps.

KeyPad brings complete MIDI control to iOS with an intuitive, touch-first interface for mobile music production and live performance. Use as a standalone app or load as an AUv3 plugin in your favorite iOS DAW.

Perfect for mobile producers, live performers, beat makers, sound designers, and educators controlling external hardware or desktop software from iOS.

ISOMORPHIC GRID

Play in an isomorphic grid where every row and column keeps the same interval, so chords and scales have one shape anywhere. Choose a single-row layout with a dedicated mod-wheel row, or a 2-row piano layout with discrete mod-wheel cells. A vibrant gradient highlights roots and notes, optional labels show note names, and per-note MPE expression with pitch bend adds full control. Grid view, layout, and root note persist across sessions.

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 full keyboard automatically. 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. XY MPE allocates per-note MIDI channels (2-16) with Y mapped to CC74 and X to Pitch Bend. Remap aftertouch or mod wheel output to any MIDI CC or Pitch Wheel. A green gradient on pressed keys shows pressure intensity in real time.

CONNECT TO YOUR MAC

Control Logic Pro, Ableton Live, or any Mac music software from your iPad or iPhone.

Wireless (Network MIDI): Connect over your local network using Bonjour - no cables required. Perfect for studio setups with freedom of movement.

Wired (Inter-Device MIDI): Plug in via USB for a rock-solid, zero-latency connection. Ideal for live performance and recording sessions.

AUV3 PLUGIN

Load KeyPad directly inside GarageBand, AUM, Cubasis, BeatMaker, Drambo, or any AUv3-compatible host. Control your instruments without switching apps. Settings save with your project.

STANDALONE APP

Use KeyPad independently to control hardware synths via MIDI interfaces, route MIDI to other iOS apps through virtual MIDI, or connect wirelessly or wired to your Mac.

TOUCH-OPTIMIZED PERFORMANCE

Height-Based Velocity: Touch keys at different vertical positions for dynamic velocity control. Three curve options customize response for expressive playing.

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

Smart Layout: Automatically adapts to your device orientation and size. Full layout on iPad, compact keyboard-only mode on iPhone or Split View.

OSC OUTPUT

Send MIDI data as Open Sound Control messages to networked applications. Enable wireless control of desktop software like Ableton Live, Max/MSP, or TouchDesigner from your iOS device. Configure custom host and port for advanced setups.
