Hello rimshots and cowbells,

Thank you everyone so much for your replies.
I think I'll go with the 4066 for the sake of efficiency.

So, I could mount the chip in the 707 and use the 707's 5V rail for the 4066's VDD input right That way, the control input to the 4066's switches could be quite low.

I'll keep you posted as things evolve. I guess this is probably time to buy a little breadboard, too...

Ciao,

Devon

BTW, Gumi, your track "Hydraulic Interruption" is really cool. Very funky.
