MidiController turns your iPhone/iPad into a complete MIDI controller, that works over USB, WLAN or Bluetooth. No additional software needed! Send all possible Notes, Continuous Controller / Control Change and Program Change values to the connected device. Build your workspace from the ground up with unlimited, custom Pushes/Buttons and Sliders. All Pushes/Buttons and Sliders are completely customisable - customize every value of every control possible and how the control behaves. You can even create dynamic controls (e.g. Program Change values that count up or down). • Works with every macOS: From 10.5 (Leopard) up to the newest 10.15 (Catalina) • Works on every iPhone and iPad • Also works with external hardware (e.g. synths,...) that supports Apple (CoreMidi) • If your hardware/PC does not support CoreMidi, you can use an iPhone/iPad compatible MIDI-Interface as bridge to make MidiController work with ALL MIDI devices Works with every application that supports MIDI-Input. Example DAWs (Digital Audio Workstation): * Logic X Pro * Ableton Live * Avid Pro Tools * Propellerhead Reason * Steinberg Cubase * Cockos Reaper * and many more (in principle every application that supports midi input) ** NOTES ** • MidiController does not play any sound itself, it only sends out MIDI-Information to connected devices. • MidiController is primary created to work with macOS-Devices. If you want to use MidiController with hardware that does not support Apple CoreMidi, you might need an iPhone/iPad compatible MIDI-Interface as bridge. A MIDI interface typically connects to your iOS per lightning port and provides standard MIDI DIN ports to connect to your hardware. There are also bluetooth MIDI interfaces that connect wirelessly. • MidiController does not receive any MIDI-Information, it generates and sends them itself depending on the user-input. ______________________________________________ APP USAGE INFO & MIDI CONTROLLER SUBSCRIPTION DETAILS Should you choose to upgrade to a midi controller subscription, payment will be charged to your iTunes account at confirmation of purchase.

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. CORE FEATURES • Built-in sound engine for SF2, SFZ, WAV, and M4A. • Piano keyboard, isomorphic grid, 9-pad drum grid, and XY performance pad. • Scale mode with 12 scales and any root key, on both piano and grid. • Aftertouch and MPE with Mono AT, Poly AT, and XY MPE modes. • Aftertouch and Mod Wheel remapping to any MIDI CC or Pitch Bend. • Velocity, Pitch Bend, and Modulation faders, plus a latching sustain button. • AUv3 plugin for GarageBand, AUM, Cubasis, BeatMaker, and Drambo. • Network MIDI, OSC output, and 16 MIDI channels + Omni. • Adaptive interface for all iPad and iPhone sizes. 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.
