[sdiy] Dual Irwin VCA update.

[synth at charlielamm.com]

I have posted a couple of "applications" based the PCB design.

http://www.charlielamm.com/synth/duallinearvca.php  (main vca page, with
links)

http://www.charlielamm.com/synth/basic.pdf  (basic vca wiring)

http://www.charlielamm.com/synth/panner.php (stereo panner).

Also, A link to Phillip Gallo gallomagnetix site, he has figured out a way
to add expo control to the Irwin design using DPDT relays.

More apps soon.....

If you find mistakes, please let me know......

Thanks....
