DIY ANALOG SYNTH appears like fun

The family member simplicity of building the private elements that comprise an analog synth make it extremely appealing to diy your own. That’s what [Albert Nyström] did as well as the result is this excellent looking, as well as excellent sounding, analog synth.

The VCOs in his monosynth are based around the AS3340 VCO chip, which is a clone of the Curtis Electromusic Specialties‘ CEM3340 chip (used in machines such as the Oberheim OB-Xa, the Roland Jupiter-6, as well as the Sequential Circuits Prophet-5 among others.) The voltage managed filters are based on Moritz Klein’s VACTROL based VCF circuits, as well as the envelopes based on Thomas Henry’s 555 envelope circuits (Google searches will dig those up quite quickly, in addition to schematics for develops utilizing the CEM chip.) Finally, the keyboard is a donor from an Arturia Keystep. While there are no step-by-step develop instructions, or a schematic, we do have some information about the instrument. As you can see from a few of the gut shots, it should be relatively simple to figure exactly how [Albert] has put whatever together. Or not.

Even if the internals are a bit wild, the end result is a excellent looking monophonic synth that does quite much whatever you’d need. If you feel the itch to cable a lot of elements together as well as make one yourself, there are messier methods to go about it. Or perhaps you’d prefer to go the digital route? Either way, synths are a ton of fun to develop as well as to play.
