A powerful MIDI modulation engine for controlling plugins, hardware, and instruments using LFOs, random sources, macros, and audio-based modulation. Modulate Everything MMM is a MIDI controller and modulation workstation designed to control any parameter that accepts MIDI CC — software instruments, plugins, external hardware, or any MIDI-capable device. Create modulation using LFOs, Random Generators, Envelope Followers, XY pads, and more. No more drawing of automation curves, keep your audio dynamic and exciting with ease. Perform Live MMM includes a dedicated Performance Skin designed for low-light and stage environments. It uses a restrained, red-accented color palette that preserves focus and minimizes visual distraction while performing. The interface remains clear and readable in dark settings, ensuring stable workflow during your live performance. MMM vs MMMm MMM includes audio input, enabling Envelope Followers, audio-reactive modulation, and audio output — ideal when used as an audio plugin. MMMm, by contrast, is a MIDI-only FX version for hosts such as Logic Pro or AUM that require a pure MIDI processor. Both versions support MIDI input and output and provide the same core modulators. MMM is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).

ReceptionRating · Positive reviews · Number of ratings

Claravox holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: GSDSP MMM has 36 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of Claravox's written reviews are positive against 67% of GSDSP MMM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Claravox ships an update every 3 weeks, GSDSP MMM every 5 weeks. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
