Matrix mixer, great utility module
For Passive Matrix Mixer Kit
I do not like kits, but this was easy to construct. I had fun building it. The matrix mixer is well designed and very compact. I use the mixer with guitar pedals and modular synths. Wild effects are possible. If you are a fan of auxiliary send/return loops in audio, then you will enjoy the elegance and power of the matrix mixer. Any input on a synth can become chaotic when paired with this mixer. I like to trigger drums, do frequency modulation, and keep the pitch shifter feedback lingering in the background. With one twist of a knob the sound starts as psycho oscillator noise, transforms into a uniform beat, slows to a crawl and ends as mellow tube preamp feedback.
