[sdiy] The start of my modular

[Colin Raffel]

Hello everyone,

I'm new to this list and the world of Synth DIY, although I have been  
doing other audio DIY stuff (mostly pedals) for a couple of years.   
This January, at my college (Oberlin), I am undertaking the project  
of building a modular from the ground up-specifically building, not  
designing the circuits, because designing a whole modular and  
building it in a month I imagine is near impossible for one person.   
But for 5-6 hours a day this January I plan on building a synth from  
designs from Ray Wilson's site, http://www.musicfromouterspace.com .   
I wanted to see if you guys thought that I had chosen a decent  
selection to get a modular started (and hopefully expand upon  
later).  I am planning on including:
1) VC LFO/O (.1hz to 20khz) http://musicfromouterspace.com/ 
analogsynth/VCO200503REV01/VCO200503REV01.html
2) VCO (10hz to 20khz) http://musicfromouterspace.com/analogsynth/ 
vco.html
3) VCLFO http://musicfromouterspace.com/analogsynth/coolnewlfo.html
4) +/- 12v Power Suply http://musicfromouterspace.com/analogsynth/ 
powersupply.html
5) Dual VCA http://musicfromouterspace.com/analogsynth/newdualvca.html
6) VC State Variable Filter http://musicfromouterspace.com/ 
analogsynth/statevariablefilter.html
7) Sample Hold/White Noise generator http://musicfromouterspace.com/ 
analogsynth/sandh.html
8) ADSR http://musicfromouterspace.com/analogsynth/norgate_adsr_001.html
9) Simple Ring Mod http://musicfromouterspace.com/analogsynth/ 
RingModulator/RingModulator.html
Then, not from Ray's site, I am hoping to build from Ken Stone's site
10) Stompbox adapter http://www.cgs.synth.net/modules/cgs46_sba.html  
and http://www.cgs.synth.net/modules/cgs60_sba.html

Do you think this is a good assortment?  Do you know of any other  
designs/replacements you would choose? I have searched around a bit,  
and it seemed like Ray had the most solid selection of simple modules  
with detailed descriptions and PC board layouts around without it  
just being a kit.  Do you think I should make the +/- 12v power  
supply or should I build a +/-15v one that would (possibly) be more  
compatible with future modules, then separately try to build a +/-  
12v step down for all of the modules?  Is there a general consensus  
about whether or not Ray's modules will work with +/- 15v or should I  
forget about that possibility?

Thanks everyone for your help, I look forward to a wonderful January  
of soldering, assembling, tweaking and (ehhh) debugging!  I will do  
my best to contribute to discussions when I can and update you all  
when it's done.
