[sdiy] Just joined the list; my first questions

[Gareth B.]

Greetings, all.

I'm a musician and filmmaker. I discovered the Eric Barbour vacuum tube 
synth schematic pages, and I'd like to ask the list if anyone here has built 
them, and how satisfied they are with the result, technically and musically.

Also, is there a reliable midi --> CV adapter for controlling analogue 
synths?

Finally, I've been unable to locate a schematic for the Ondes Martentot. If 
anyone knows of a URL where this might be located, I'd be very grateful to 
receive it.

Many thanks in advance --

Paul
