Hi Ray,<BR>
<BR>
You certainly have a prolific imagination. The VCA on the MS-20 design is the smallest parts count I have seen. Thank you for posting these many designs, there are a lot of good ideas there, and the designs are right up to date with 13700s for OTAs.<BR>
<BR>
It's very public spirited to post such a generous amount of useful information.<BR>
<BR>
Best Regards,<BR>

<FONT SIZE="2"><FONT FACE="Arial">The WP20 is not what I would consider a synth but it is more of a sound generator. Its a very old design and I'm betting you will find far better ones. I whipped it up (I can hardly say designed) when I was very inexperienced in electronics 22 years ago. As a project it will provide: parts gathering, PC board making, soldering, and construction experience and you can make some half decently cool sounds with it but... The circuit designs are all very rudimentary and if I do say so myself quite low quality. My suggestion... keep looking and you will find a better design or even a kit. The WP20 link is more for historical information than anything.<BR>

<FONT SIZE="2"><FONT FACE="Arial">Again the circuits aren't temp compensated or drift free but they are better than in the WP20. It will provide a newbie with a very fun device for making cool sounds and getting a better understanding of how electronic sound generation works.<BR>

<FONT SIZE="2"><FONT FACE="Arial">Hope this helps.<BR>
