<DIV><FONT face=Arial size=2> I am attempting to put together
a modular synthesizer made entirely, or as much as possible, with vacuum tubes.
I have gathered much information from many of you at various web sites. I am
almost ready to bread board several designs I have modified or procured from the
web, some out right ridiculous like a moog ladder with vacuum tubes but I am
having difficulty with a reasonable design for a keyboard controller. I would
like to use the one volt per octave standard that seems to go along with the
majority of equipment. I can't seem to find a descent schematic or tutorial to
guide me through the basics of the control circuit and it's drive of the VCO.
Any and all help would be greatly appreciated.</FONT></DIV>
