Re: Hardware hack - replacing a pot with a switch?

[John Tidwell <wedgehed@yahoo.com>]

I had a similar notion with my Digitech RDS 7.6.
What I tried to do was scale the delay time of the
RDS to the pedals of a Roland PK-5 via a midi/cv
converter. Since the RDS has a CV input, I didn't
have to alter the circuit. I spent a day or two
messing around with this combination. It was fun to
play with but it never behaved in a predictable
manner. Pedal combinations that produced an octave
jump one time would fail at another. My assumption
was that the RDS simply behaved differently at
various operating temperatures.
