Strange Loop vs Maxy MIDI
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Strange Loop
This app generates unique, non-repeating music using chaos theory and AI. Users can influence the composition by painting on mathematical attractors and mood pads, choosing from various scales, accompaniment styles, and synthesized sounds. It also functions as an AUv3 instrument and MIDI processor.
- AI-generated, non-repeating music
- Interactive painting on attractors and mood pads
- 26 scales and 7 accompaniment styles
- Sampled grand piano and synthesized voices
- AUv3 instrument and MIDI processor

Strange Loop writes its own music. Three coupled Lorenz attractors drive the piece — one proposes pitch, one shapes rhythm, one wanders the emotional plane. A Markov policy then decides what actually plays, learning from its own output and rewarding intervals that sound consonant. Chaos proposes, the policy disposes. Slide BLEND to choose who wins. Nothing is pre-recorded and nothing loops. Every run is new. PAINT ON THE MATHS Both scopes are paintable. Draw on the attractor and the trajectory bends toward what you drew and lingers there, pulling the melody into those pitches. Draw on the mood pad and the feeling follows your strokes — brightening the harmony, lifting the register, pushing the tempo. Set how hard the ink leans, how big the brush is, and how long it lasts before it fades. WHAT YOU GET • 26 scales — major and minor modes, pentatonics, blues, whole tone, harmonic and melodic minor, altered, both octatonics, and folk scales from Japan, China, Egypt, Spain, Arabia and Hungary • 7 accompaniment styles — chaos grooves, jazz comping with walking bass, stride piano, Alberti bass, classical, arpeggios, ambient rolls • A sampled grand piano plus synthesised voices: soft piano, glass, strings, FM bell, AM organ, pluck, fat saw and more • 6 moods on a valence/arousal plane, from serene to tense, driving chord quality, register, tempo and note length • Live scopes — the attractors, the note-probability distribution the engine is sampling from, and the mood point, all drawn in real time • Deep control: key, scale, tempo, chaos rho, rhythm spread, grace notes, chord-tone pull, softmax temperature, per-track mixer • Record a take and export it as a standard MIDI file to the Files app — melody, chords and bass on separate tracks TWO AUDIO UNITS Strange Loop ships as an instrument AUv3 and as a MIDI processor AUv3, so it can either play its own sounds or sequence any other instrument in your host. Melody, chords and bass each send on their own MIDI channel, so one instance can drive three different instruments. Both Audio Units follow your host's transport and tempo — hit play in AUM, GarageBand, Logic, Cubasis or Zenbeats and it locks to the grid. One install registers both.

Maxy MIDI turns an iPhone or iPad into a MIDI controller you design yourself. Drop knobs, faders, pads, keyboards, launch grids, mixer strips and DJ controls onto a page, set what each one sends, and play. Boards and pages Every board is a set of pages, each on its own MIDI channel, laid out on a grid. Tap a tab to change page while you play. Boards are saved on the device, exported as files and shared by AirDrop, so a layout built on an iPad can be opened on a phone. Controls Rotary knobs and endless encoders, vertical and horizontal faders, motorised faders that follow the DAW, XY pads, ribbons, pitch and modulation wheels, buttons and toggles, velocity pads and drum racks, a piano keyboard, Launchpad-style clip grids, transport buttons, mixer strips, crossfaders, three-band DJ EQ with kills, and a deck with a jog wheel. Velocity is measured by where your finger lands, by how much glass it covers, or fixed. Getting to your computer Wi-Fi network session for a Mac or for rtpMIDI on Windows, Bluetooth LE, USB cable, and virtual ports for other apps on the same device. MIDI 2.0 is used where the port supports it. There is a MIDI monitor for when something is not arriving. Speaking your DAW's language Mackie Control for mixers and transport, HUI for Pro Tools, and OSC over UDP for Reaper, Bitwig, Resolume, TouchDesigner and VCV Rack. An Ableton Live remote script is bundled and can be sent to your Mac. Controller scripts for Bitwig and Reaper can be generated from a board. Generators A clock that sends MIDI clock or follows one, an arpeggiator, chord pads, a step sequencer with conditional trigs and probability, a Euclidean sequencer, an LFO to any CC, note repeat, a note echo, a Turing machine melody, and a beat generator with hand-written patterns for two dozen genres. Ableton Link is supported when the LinkKit framework is added. Made to be simple Every control works the moment it is dropped on a page, with a sensible default. The inspector shows the common settings first and hides the rest. MIDI Learn wires a control to whatever you move in the DAW. More than sixty templates give you a layout to start from, from Serum and Diva to Logic Pro, a drum rack and a DJ board. What you need to know MIDI does not tell software what to do by itself. It sends numbers on channels, and the software at the other end decides what those numbers mean. A template is a layout whose numbers never clash. Hardware boards are wired from the maker's MIDI chart; the Logic, Bitwig, Cubase, Studio One and Pro Tools boards speak Mackie Control or HUI, which those DAWs take once you add the surface; Ableton Live has a bundled script. For everything else you map the controls in your DAW, usually by moving a control in Maxy MIDI while the DAW is listening. Each template says which it is, and the app has a walkthrough that sends each control in turn to make learning quick. Free and Pro The free app gives you one board of three pages, one of each kind of control on a page and one generator at a time, and lets you open and play every template within those limits. Maxy MIDI Pro is a one-time purchase that removes the limits, keeps templates as boards of your own, turns on board export and sharing, OSC sending and the rest of the beat genres.

Verdict
The clearest difference is device support: Strange Loop at 4 against Maxy MIDI's 2. Strange Loop also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.
