[sdiy] VC and CV keys

[Pat Kammerer]

Hi all,

I've just got two questions, and you all seem to know what you're doing, so
I'm sure someone will be able to help.

1)  Is it true that to protect components in a circuit, the CV will need to
be below the supply voltage of the circuit?  Would this be best done by
having the CV supply lower than the supply of any of your modules, are by
limiting the input with zener?  Maybe I'm missing a method, any help
appreciated.

2)  I am building a CV keyboard, and I know the basics of getting CV, Gate,
and trigger outputs of the switches.  My question is, does anyone have
recommendations for the resistor chain?  What values have you used with
success, and do you use trimmers?  In my protoboarding, I've been using 2M
panel mount trim pots (intended for tube circuits), but these seem to not
have the correct senesetivity or range for finetuning, while they are fine
for just learning the basic circuit layout.

Thanks in advance!
Pat
