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.
Fixed doubled/ratcheting notes in AUv3 by not injecting UI notes into host MIDI.
Fixed MPE pitch bend snapping back to center on release.
