## What is 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).

### 5/5 — Amazing!!!!

*2025-06-15*

This thing is everything!!! Paired up with all my other apps, this modulator just breathes life and movement into my programming. Extremely flexible and amazing mod options!!!!!!

### 5/5 — MIDI-only version, not “little brother”

*2024-07-29*

This is the MIDI FX version of MMM, which shows up as an audio FX as it has an input follower, you want both versions and they should be packaged in the same download together rather than create this confusion. I thought “little brother” meant this was a simplified version but instead it’s complimentary.

**Developer response:** Thank you! We tried to offer it as a bundle but unfortunately this is only possible for paid apps or apps offering in-app purchases…

### 5/5 — NextGen Modulators

*2024-03-15*

This probably deserves the best app of 2023 award. It works seamlessly and intuitively. The level of control and possibilities are astonishing. It‘s 100% reliable and it‘s free. This is by far the best modulation system on iOS and is on a desktop a great addition even to bitwig.

**Developer response:** Thank you so much for such praise. Nothing beats the feeling of knowing our stuff is helping people create! 🥰

### 5/5 — Incredibly useful

*2024-01-17*

This app has a lot of potential uses, particularly given the range of modulation and envelope following features. It can transform your workflow as you are able to centralize a lot of the parameter tweaking all in one place.  

My only suggestion would be for it to be possible to choose to “hide” knobs or sliders that are not being utilized to cut down on the visual clutter. The number of options can be overwhelming at times when used with specific apps rather than full-on devices, and it would be simpler to only have what I need, (perhaps have each block have an individual on/off accessed through the same menu where the cc info is set). Having additional templates with either just the top or bottom sections available would also be useful. 

Overall it has a lot of features and allows me to use one app versus the string of apps I had been using before to acquire similar levels of control.

**Developer response:** Thank you very much for the kind and thoughtful review. Your suggestions are interesting and we will definitely keep them in mind.
