Kosmo Sequential Switch

[image] [image] This is one of the modules I’ve been working on, the Kosmo sequential switch based on the fonitronik design. (fonitronik modular synth diy) It is a nice multipurpose utility module for cv or audio routing, apparently any signal up to 12v. It has one input that switches between up to 4 outputs and is reversible (4 in, 1 out), with manual push button and cv controlled reset and “clock.” As well as a switch to select how many switch steps you want to cycle through (2-3-4). For e…

Kosmo format multiples

[image] [image] [image] Pcb sets for two types of multiples both in 5cm kosmo, a doepfer style switched-mult and a buffered/passive mult combo. There isn’t a whole lot to say about them, the buffered mult is one of the better ones I’ve seen in opinion, with trim pots on each output so you can match them exactly. Here is the original schematic: [image] I changed his fancy pants resistors and the trim pots and still have the outputs tuned to within .01v of each other. I doubled the design fo…

Kosmic Taxidermist

Finally getting back into some kicad noodling, working on modding and porting the “Phonic Taxidermist 47.2b” from circuitbendersUK to a kosmo faceplate: it is basically a delay as well as a strange “distortion” circuit (they call it a chopper). it sounds like it has a ring mod to bit crush range of effect. it works by strobing the audio signal at different frequency bands which can be selected with the four switches. a guy on muffwiggler by the name of MCOP has also added gate control to the…
