I am interested in building some simple analog synth modules.  I have seen the paia stuff, and it looks great, but I'm wondering if anyone can point me to simple schematics for individual modules?  I really want to start with the basics.  I think it'll also help my general electronics understanding. 

I'd like to start with a simple analog oscillator that will give me a square, sine, sawtooth, and triangle wave.

Can anyone point me in the direction?
 
See this page, many designs there are based to old Electronotes (Bernie Hutchins, http://electronotes.netfirms.com/ ) designs (I think, with small changes):

Print the schematics and circuit descriptions, very good reading for studuying analog synthesis circuits!

Elby Designs sell kit & pcb for ASM-2 which is the successor of ASM-1 presented above:

You can start building from PSU (guess it's needed anyway), then continue to VCO's, EG's etc. as you like.
 
Look at the Paia modules near the bottom of my page at:

John Simonton gave me permission to post those items before his premature death in 2005. (RIP)

If you want a blast from the past, an article from the Journal of the Audio Engineering Society in, I think, 1965 gives schematic diagrams for Robert Moog's first modules. I built the oscillator, which worked, and some of the others, which didn't -- probably more a function of my poor technique than anything else.

Peace,
Paul
