I found myself short of an ADSR in my system and it annoyed me to no end I hadn’t thought of buying a few more. Instead of hitting the favourite Eurorack module dealer for my fix I went googling to see if I could cook up one of my own. Couldn’t be that difficult. Right. Turns out, there are tons of useful ADSR schematics floating around on the internet. Continue reading “ADSR”
This is an envelop follower. Since I build an input module I kinda wished I had one of these so I made it a little project, fun for the whole family well, not really, but anyways..) Continue reading “Envelop Follower – Follow Moe”
Since Coolaudio started reissuing old IC’s used in various synths I always eyed the V3340, which is a reissue of the CEM3340 chip as used in many classic synths such as the Roland SH101, Prophet 5, Memory Moog and plenty of others. It’s, in essence, a fully featured 1V/oct oscillator on a single IC and thus takes away a lot of the headaches inherent to VCO design. Things like linearity and temperature compensating are taken care of for you. This takes away a lot of the pain of building VCO’s, in fact, since these IC’s are available again a DIY polysynth starts to become a possibility.
