Modular Synthesizers

This is my very first modular synth which I built during the Covid-19 lock-down ;) I decided to use the Kosmo Format because I like its pragmatic nature. Big jacks, panel sizes which are compatible with the cheap aluminum sheets on eBay, Eurorack-compatible electronics (+-12V, 2x5 and 2x8 pin IDC connectors) etc. A more detailed description will follow soon.

Abstract A simple 4x3 buffered multiple which can easily be fit on a 46x16 stripboard. The schematics are based on the 1161 Buffered Multiple from Sam Battle (aka LOOK MUM NO COMPUTER). Introduction Alright, this is a very simple yet absolutely essential module in a modular synth: the buffered multiple. Why is it called multiple? Because it’s makes multiple signals out of one by replicating it. What does buffered mean? In contrast to a passive multiple which is basically a cable distributor, a buffered multiple not only replicates the signal on each of its outputs, it also buffers them in the sense that it decouples it from the original current source....
