RE: expression pedal with all access
sorry to exhume thread but I got a new piece of gear and i'm a bit
I got the CP-251, which is a control voltage mixer/controller. It
it's own expression pedal which has a single line out of the thing. Does
anyone have experience with this and can they offer a suggestion on whether
I need to buy this or can jerry-rig something else?
My guess is that it's just a TRS line which could be duplicated through my
Ernie Ball mono pedal using a TRS breakout cable. Anyone know if this is
true? I am reluctant to experiment with the thing and short it out by
accident. Log range is OK.
Thanks in advance,
PS my application is controlling the Sherman which I monkey'd with last
night and it is just wicked. But I'd like to get a VCO kit too...

you can use the ernie ball as-is with a standard insert cable, but you
get a log curve - the middle position of the pedal does not
translate to the middle of the control range.
in other words: if you set your control range to 0-127 (default),
the middle pos of the pedal will not result in a cc of 64...
in order to get this behavior, you have to replace the audio taper
pot with a linear taper pot...
