Matrix mixing craziness

A few weeks ago I did a small experiment with summed matrix mixing:

sounds great, crazy, untamed etc. I decided to explore summed matrix mixing a little bit further and today I started building a new prototype, that got out of hand quickly!

A single attenuverting channel (a 1 to 1 matrix) looks like this:

Although interesting, a more advanced matrix would offer a lot more possibilities. I decided to go for a 4 x 3 matrix, since I had those parts available. A 4 x 3 matrix offers 4 input channels that can be annenuverted and routed to 3 output channels, in any configuration. The test configuration will be configured like this:

And, it got out of hand. 4 channels “in” means:Screen Shot 2016-04-01 at 20.58.42

this, and to have 3 channels “out” — multiple this by three! Which leads to a breadboard like:


;) Time for extensive testing!
