I too am making my own modular and started with a Thomas Henry design. I have made a VCO-1 VCF-1 and VCA-1. It sounds amazing and was a lot of fun so commited to a 5u setup 600mm wide and 2 rows tall. I plan on updating the vco-1 with a vco555, and adding a whole slew of Yusynth projects.
http://yusynth.net/Modular/index_en.htmlYves Usson did the design and stuff for the Arturia synths. I picked up a minibrute to interface with my modular, CV with an extra ADSR and LFO. It's awesome to see other diy'ers out and about (outside of the Muffwiggler and electro-music forums).
Thanks heaps to pitagoras aswell! I got quite a bit from those links that I hadn't seen before. Especially like the Prophet 6 breakdown.
I know little about the modern day microprocessor electronics, coming from a more guitar oriented background. Cutting my teeth on a silverface fender amp and redoing its power section has prepared me pretty well for not missing the small stuff/touching the wrong thing! I can't help but love the old way, turret boards and point to point artwork. But in the quest for DIY synthesis I'm keen to find out why X sounds different to Y. And I want to breadboard it up myself to see and hear the difference.
For instance I'm making two Yusynth VCO's at the moment. And like Jennifer my first oscillator was just there and worked. Now I can point out the parts and whys of the design. Mostly
