MIDIx vs Beat Kitchen Harmony Wheel
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
MIDIx
This app uses physics simulations to generate expressive MIDI data. Control parameters through object movement or create generative note sequences. It's a unique tool for musicians seeking organic and evolving soundscapes.
- Physics-driven MIDI CC generation
- Generative MIDI note sequencing
- AUv3 plugin support
- Customizable physics scenes
- Built-in scale library
- Real-time modulation
- Universal app for iOS and Mac

MIDIx brings a new dimension to MIDI control. Instead of programming sequences or drawing automation, you let physics do the work. Objects bounce, fall, orbit, and collide — and every movement becomes expressive MIDI data in real time. MIDIx is a universal app for iPhone, iPad and Mac, and supports AUv3 so you can use it as a plugin directly in your favorite host. Organic CC Controller The CC page gives you 8 independent physics scenes, each generating two MIDI CC values — X and Y — from the motion of a physical object, for up to 16 simultaneous CC streams. Each axis maps directly to its CC value, creating smooth, organic modulation that no LFO can replicate. Each output can be assigned to any MIDI CC parameter — or to a parameter of another scene, enabling complex modulation chains where one physics engine drives the behavior of another. Hit Freeze to instantly hold the current motion in place, perfect for locking in a value during a performance. Generative MIDI Sequencer The Notes page transforms physics into melody. Add as many objects as you want to the scene — each one bounces freely and triggers a MIDI note every time it hits the wall. Shape the motion with additional objects — Static, Bumper, Planet, and Repulsor — to create richer, more unpredictable interactions. Build evolving, generative patterns that shift organically over time. No two performances are ever the same. Define your harmonic space and select individual notes to craft any scale you need. Tap Scale Library to instantly load a preset scale: Major, Minor, Pentatonic, and many more. Features: • 8 physics scenes generating up to 16 MIDI CC streams (X and Y per scene) • Generative MIDI note sequencer with unlimited objects • Continuous or Trigger play mode, adjustable update frequency • Freeze button to instantly hold the current motion • Adjustable min/max range per scene to fine-tune CC output • Assign any CC or scene parameter as a modulation source • Static, Bumper, Planet, and Repulsor objects for richer motion • Built-in Scale Library with custom scale editing • Adjustable root note, base octave, octave count, and note duration • Notes custom mode (select the notes you want) • Preset import & export • Randomizer • Undo support • Built-in user guide • Background audio support • Full MIDI support & MIDI Mapping • Full AUv3 support — standalone or as a plugin in your favorite host • Universal app for iPhone, iPad, and Mac Questions or feedback?

The Beat Kitchen Harmony Wheel is a musician and producer toolkit — a tuner for chords and a measurement device for the vitals of the music in front of you. Point it at your mic or play it over MIDI, and it reads the harmony as it happens — the chord, the key, and the job that chord is doing. Works on piano, guitar, or recorded music with clear harmonic movement. It identifies each chord's role, not just its name, using the Beat Kitchen Ten Chord Toolkit (explained in the guidebook built into the app): the tonic (I) you keep coming back to, the IV that opens things up, the V that wants to resolve, a V/vi setting up a detour, a bVII pulled from the parallel minor. The matching wedge lights up as you play. What it does Hears chords from your mic in real time, right on your device — nothing leaves your phone Labels the wheel by function, not just by chord name: I, ii, IV, V, V/vi, bVII, and the rest Records what you played so you can study the path a progression took Tap any wedge to hear the chord Takes MIDI in, wired or over Bluetooth, with a built-in synth Locks to your key so the wheel orients to the music you're in A Learn tab that walks through what you're looking at If you've reached for a circle of fifths or a key finder before, you're in the same neighborhood — except this one works in real time, while the music is still playing. Producer Tools A tuner and a metronome, built for the studio. Check your tuning. Tap a tempo or let the mic detect it for you, then read it in BPM and in milliseconds for every subdivision — with your own click sound on each one. Watch the beat pulse from across the room and feel it in your pocket with haptics (iPhone). And because the wheel already reads your key in real time, it doubles as a key detector for DJs lining up harmonic transitions. Who it's for Producers, DJs, songwriters, students, and anyone who can tell a progression is doing something to them but can't always say what. You don't need to read music. You need to be curious about why a few chords in a row can move you. It's theory you can hear before you can spell it. Beat Kitchen is a school that teaches harmony by ear and by function first. Harmony Wheel puts that same way of listening on your phone.
