KeyPad MIDI Controller

SFZ, SF2 Player · Piano & Pads

Free · Designed for iPad

Transform your iPad into a professional MIDI controller with touch-optimized piano keyboard, drum pads, and XY performance controls. Control iOS apps, hardware synths, and Mac software wirelessly or wired. KeyPad brings complete MIDI control to your iOS device with an intuitive, touch-first interface for mobile music production and live performance. Use as a standalone app or as an AUv3 plugin in your favorite DAW. Perfect for mobile producers, live performers, beat makers, sound designers, educators, and anyone controlling external hardware or desktop software from iOS. CORE FEATURES • Built-in sound engine supporting SF2 SoundFonts, SFZ instruments, WAV, and M4A samples. • 2-Octave Piano Keyboard with responsive touch control. • 9-Pad Drum Grid for finger drumming. • XY Performance Pad with configurable CC assignments. • Velocity, Pitch Bend, and Modulation faders. • Sustain pedal button with hold functionality. • Height-based velocity with Linear, Exponential, and Logarithmic curves. • Aftertouch and MPE expression with Mono AT, Poly AT, and XY MPE modes. • Aftertouch remapping to any MIDI CC or Pitch Bend. • AUv3 plugin for GarageBand, AUM, Cubasis, BeatMaker, and Drambo. • Network MIDI for wireless control of Mac apps. • OSC (Open Sound Control) output. • 16 MIDI channels + Omni mode. • Adaptive interface optimized for all iPad and iPhone sizes. BUILT-IN SOUND ENGINE Play sounds directly without any external app. Load SF2 SoundFonts with multi-preset program selection, or import SFZ, WAV, and M4A samples for custom sounds. 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-axis mapped to CC74 and X-axis to Pitch Bend for full MPE expression. Remap aftertouch output to any MIDI CC, Mod Wheel, or Pitch Wheel. Visual green gradient feedback 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 where you want 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. All 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 simultaneously 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 like Ableton Live, Max/MSP, or TouchDesigner. Configure custom host and port for advanced setups.

Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

Added 3D wheel-style rendering for pitch bend and mod wheel sliders, with position-tracking gradient, sine-based bulge highlight, and variable-thickness handle line. Consolidated MIDI Channel and MIDI Out into a single MIDI submenu with disabled section labels for grouping. Fixed drum pad highlighting to toggle pad state instead of lighting up the MIDI keyboard. Fixed velocity 0 bug in height-based velocity mode. Clamped minimum velocity to 1/127 and velocity fader minimum to 1 to prevent Note Off messages.
