[sdiy] More questions from the hack: low frequency cutoff of vco?

[Rob B]

well, thats prlly the last thing you want to do is to get a big honkin cap
stuffed in there.. hehe..

Best thing is to find the discharge path of the cap and put a bigger
resistor in it (or replace it with a big pot for real fun)'

This sort of thing works well for most non-critical VCOs such as drum vcos.

aim : cybrgzr0 <--last thing is a number
