## What is GSDSP MMM?

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).

### 5/5 — Powerful

*2025-01-20*

But you need to know how to use it! There are tutorials on YouTube. Disregard negative reviews.

### 4/5 — Looked useful, but..l

*2024-10-24*

As the title says, this looked like a well featured and useful app. However, about three or four updates ago, the app refuses to do anything but open a black screen on my iPad Air 2. I realize that this has been a free download and I have an older device, so I don’t want to sound unreasonable and ungrateful. I rated the app fairly highly for what it used to do. If updates have moved on without me, I can accept that for something that I did not pay for. I am writing this comment just because I thought that you might not know what is happening.

**Developer response:** Thanks for the feedback. Please contact us via our website to report the details of issues. We take all reports seriously and work hard to make quality software.

### 5/5 — Amazing offering, ignore immature reviewers who don’t understand how to use it

*2023-06-14*

This is a true gift from devs who offered it free. It’s pretty immature and entitled for someone to rate low simply because they are not at a level of experience or skill in using an alp that controls MIDI. That type of thing will only influence devs to not offer freebies because then someone downloads and hasn’t taken the time to understand if the app is right for them or their skill level and it’s easy enough to watch YouTube videos to learn more. Thanks to the devs for offering this and making some of the most unique apps in the store,

**Developer response:** Thank you for the very kind words! We hope this brings you many many hours of creative fun.

### 2/5 — what does it do though??

*2023-06-11*

i try adding it to tracks as an effect in cubasis but it doesn’t do anything? i’ve tried everything it just won’t work

**Developer response:** Hi! This is not an audio effect it’s a midi controller. It can be inserted as an effect because some of the modulators can use an audio input signal to drive their output. This is a really cool feature that you won’t see elsewhere ;) Check out our website or search YouTube for tutorials and reviews.
