MPEdie is an MPE keyboard controller for iPhone and iPad. It makes no sound: it plays whatever instrument you send it to, and it gives every note its own MIDI channel — so every note bends, breathes and changes timbre on its own. On an ordinary keyboard a bend moves the whole chord. Here it moves one note. APP AND AUv3 Run it standalone and send MIDI to other apps on the device, to Bluetooth gear or over Wi-Fi. Or load it as an AUv3 MIDI plugin in your host and route it straight to an MPE instrument. FOUR PLAYING SURFACES • PIANO — the keyboard your hands know. Sliding follows the pitch under the finger, not the width of the key. • ISOMORPHIC — a grid where a chord shape is the same in every key. Rows, columns and row interval are yours to set. • RIBBON — one continuous strip, nothing to land on. You choose how many semitones fit across it. • SCALE GRID — the same grid, with only the notes of the chosen scale. Nothing out of key by accident. Fourteen scales, any root, split the surface in two with its own layout and octave on the right. EVERY FINGER MOVEMENT IS ROUTABLE A matrix of seven destinations — bend, timbre, pressure, strike, lift and two free CCs — and eight sources: sideways glide, absolute or relative position in the key, contact area, force, time held, or a fixed value. Each link has a curve, a gain, an offset and an invert. And an honest answer about pressure: iOS glass does not measure how hard you press. It measures contact area. MPEdie can send that, and it says so instead of pretending — it is one tap away in the matrix, and the factory default is a gesture you can predict. BUILT TO AGREE WITH THE RECEIVER Lower, upper or split zones. Member channel counts. Per-note and master bend ranges. RPN sent to every member channel when your instrument needs it. Channel pressure or poly aftertouch. Any timbre CC. Channel stealing by oldest or quietest, with a cooldown. One button resends the MPE zone setup to an instrument loaded after you. UNDER THE HANDS PANIC that also lifts the pedal. Octave and key count. Four glide modes — continuous, snap, locked, per-note lock. Pitch, modulation and volume strips, with a spring you can switch off. Two assignable XY pads. Sustain, momentary or latching. Latch, with held notes drawn apart so a stuck note never looks like a played one. Bank select and program change, sent when you ask and never behind your back. TWENTY-SIX PRESETS Seven folders: keyboards, grids, ribbons, splits, scales, and a Targets family that answers the same question — what does the receiver actually understand? — five different ways. Save your own; they are plain files you can move and share. A FREE COMPANION FOR MAC AND WINDOWS MPEdie Desktop receives the iPad over the network and republishes it as a virtual MIDI port, so your DAW sees MPEdie in its list of MIDI inputs, exactly like a hardware controller. That is the point: an input gets recorded. Arm a track and the DAW writes down the per-note expression — every note's own bend, pressure and timbre — and plays it back. Nothing is installed on the iPad, and no driver on Windows. Free download from the developer's site. The full manual is inside the app. MPE (MIDI Polyphonic Expression) is an open standard published by the MIDI Association and AMEI. MPEdie is MPE-compatible.

I think you be able to tune it differently I’m not sure, but 4ths are a great start. ### 5/5 — finally a good one *2026-08-26* and free! been waiting for this for years, thank you! ### 5/5 — Works *2026-08-26* I use Audiobus and it works as expected there. Nice and clean interface. ## Frequently asked questions about MPEdie ### What is MPEdie? MPEdie is an MPE (MIDI Polyphonic Expression) keyboard controller for iPhone and iPad.

MPEdie was last updated on August 31, 2026, indicating active development and support. ## Version history (last 4 releases) ### 1.1.3 — 2026-09-07 What's New • Bugfix: Custom scales can use accidentals. • Update: The keys of that octave are now named by degree — 1, b2, 2, b3, 3, 4, #4, 5, b6, 6, b7, 7 — ### 1.1.2 — 2026-09-06 App Store Connect — What’s New Fixes from player reports. • Y_REL works in both directions. Move your finger up and the value rises, down and it falls, with the full range reachable from wherever you landed. Before, only one direction did anything. • Two-sided sources (X_GLIDE, Y_REL) now centre on their destination instead of being clipped: no movement means 64. • MPEdie no longer sends MIDI while you are not playing. It used to repeat its MPE zone setup every two seconds for as long as it was open — which also pushed your instrument’s CC 74 back to 64. It now repeats for the first twenty seconds only, and sends nothing that moves a value. • The guide line (INFO ROW ▸ VALUES) shows every value going out, pitch bend and free CCs included, each CC under its own number. • AUTO MCM, in SETUP ▸ ZONE: turn it off and MPEdie sends nothing at all until you play. Presets leave it alone. • You can now choose the numbers for CC A and CC B — SETUP ▸ MATRIX, CC # at the end of their row. One put on a number already used on that channel stays silent instead of fighting for it. Presets saved by earlier versions are converted as they load. ### 1.1.1 — 2026-08-31 NEW • DRUM PAD — a fifth layout. A grid of pads, from 1×1 up to 8×8, each with its own note; the factory setting is a General MIDI kit with the kick bottom left. PAD MIRROR splits it into two identical grids, one per hand. • A new Drums family of four factory presets, so a pad is playable the moment you pick it. • Build your own scale, degree by degree. • Note names on every key, not just at the octaves — LAYOUT ▸ NOTE NAMES. • INFO ROW: the line above the keys can now also show what the newest note is sending, not just which note it is. • Two more glide modes. LOCKED sends no bend at all, so sliding plays each key like a piano. PER-NOTE LOCK decides note by note: move within 120 ms of touching down and it slides, wait longer and it locks. FIXED • MPEdie now works as a MIDI plug-in in Drambo. (Thanks to Robin B., who spent four days testing this with me). • MPEdie now tells its host that it speaks MPE. • INVERT had no effect on five of the seven destinations — including velocity, which is why inverted velocity did nothing. • A scale can no longer be left without its root note. MPEdie Desktop, the free companion for Mac and Windows, turns the per-note expression from your iPad into a MIDI port your DAW can record.
