MIDIx vs Ring Modulator
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?

Ring Modulator
This app creates unique metallic and bell-like timbres by multiplying two audio signals. It offers three modes for versatile sound design, from internal oscillators to sidechaining external audio.
- Ring modulation effect
- Dual input capability
- Three distinct modes (OSC+OSC, INPUT+OSC, INPUT+SIDECHAIN)
- Mono and stereo input support
- Adjustable carrier and modulator frequencies
- Mix and output gain controls

Ring modulation multiplies two signals together sample by sample. The result contains the sum and difference of their frequencies, the sidebands, while the original carrier and modulator tones are suppressed. This produces the metallic, bell-like, and clangorous inharmonic timbres associated with classic ring modulators, from robot voices to detuned percussion. Signal path: the carrier is multiplied by the modulator to form the wet signal, Mix blends that against the dry carrier, and Output applies a final makeup gain. Ring Modulator is usable in three modes and can take either mono or stereo inputs. The host app must support mixing to bus inputs or sidechaining in order to use Ring Modulator with dual input. Outputs mono signal. OSC + OSC Both carrier and modulator are internal sine oscillators, set by Car Freq and Mod Freq. Produces classic two-tone ring modulation with no input required, good for bell tones and metallic drones. INPUT + OSC The carrier is your track's audio and the modulator is the internal sine at Mod Freq. This is the standard ring-mod effect: it turns voices and instruments metallic or robotic and adds inharmonic sidebands. This is the default mode. INPUT + SIDECHAIN The carrier is the main input and the modulator is a second, independent input routed into the plugin's sidechain bus. Use it to ring-modulate one track by another, for example a vocal shaped by a drum loop or synth pad. This requires a host that supports sidechain routing; if nothing is routed to the sidechain, the input passes through dry. Car Freq and Mod Freq do not apply in this mode.

Verdict
The clearest difference is price: Ring Modulator at $1.99 against MIDIx's $8.99. MIDIx's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 17.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.
