GSDSP MMMm

A powerful MIDI modulation engine for controlling plugins, hardware, and instruments using LFOs, random sources, macros, and audio-based modulation.

Modulate Everything

MMMm 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

MMMm 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.

MMMm is an AUv3 midi 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).
