What you are looking at is three Mattson Mini Modular filters housed in one 5U module made by Luka. The image is from this post on Muff's showcasing what people have made with MMM DIY modules. If you have an account on Muff's and are logged in you should be able to see the others. If not, I grabbed a few of them for you to see in this post as follows:BananaPlug's "Squiggletronics edition of the MMM State Variable Filter. I added a 2nd CV input and an attenuator on the audio input. Getting this into one frac unit with 16mm Alpha pots was a tight squeeze. The skinny Davies knob kock offs make it easy to use. The jacks are Serge color code because that's how I do all my 3u banana conversions Blue acrylic panel from Pro-Modular with a bit of white spray paint."
Adam V's Frac 4x Gate Delay, and...
negativspace's "Quad VCA, kitbashed into a VC-mixer via a CGS DC Mixer board, with a side of LEDs."
One thing worth noting about MMM DIY is the circuit boards come fully assembled. Wire and Cable kits are available. You then go from there designing the faceplate, and selecting your knobs.
