GS DSP releases Magic Midi Modulator (MMM), a free MIDI modulation VST plugin for Windows and macOS.
There are so many instruments and effects out there for free, which means that more creative effects are sometimes forgotten. This is especially true when it comes to free plugins that manipulate MIDI.
Thankfully, GS DSP is here with the recently released Magic Midi Modulator (MMM) to give everyone a little MIDI madness.
MMM looks rather nondescript when you first initialize it. However, that is selling its overall power extremely short. At its core MMM allows a user to manipulate 24 different MIDI CC parameters at the same time.
These 24 CCs are divided into 16 rotary knobs, a pair of XY pads, a pair of horizontal sliders, and a pair of vertical sliders. CC messages can be sent to software or hardware, MMM isn’t picky. The actual implementation of this is quite quick and to the point as well.
Each of the freely available parameters can be named, renamed, muted, or soloed, so you get a great amount of control over how you’re implementing things. You can effectively manipulate just about anything you can dream of on MIDI devices and have a great amount of fun doing so in the process.
A lot of the fun with MIDI comes from modulating everything on a synth to get some evolving textures or movement.

MMM offers this in spades, with a further 24 modulators available freely. These can be tempo-synced or free running, depending on your preferences. Modulators can be freely assigned to any parameter as well.
There are LFOs, custom LFOs, random sources, and followers. The followers, in particular, get truly out there, not just adhering to the amplitude or pitch but also things like the spectral brightness or flatness of a signal.
If you’ve found yourself loving a particular synth, like u-he’s Repro, and lamenting that it is just missing the means to get wacky with it, then MMM has your back.
MMM is provided free by GS DSP and is available for Windows, Mac, and iOS devices. Supported plugin formats are VST3, AU, AAX, and AUv3.
The Mac version of MMM is universal, meaning Intel and Silicon users get to jump in on the fun.
