I have been using a Dunlop Volume X as an expression and it works great I just missed the spring load Mission EP-1 I used to use in previous rigs. So I pulled it out if the box and it will not stay calibrated. I’ll leave from a studio session, get home, turn everything on to rehearse and it’s a half note off on pitch effects. I look at the calibrate page and it’s not calibrated correctly. So I calibrate it, rehearse, head back to a studio and it’s off again. Is anyone having problems with an EP-1 or is this a known problem?
Thinking back, I’m pretty sure I ended up using the Dunlop because when I first got the KPA I tried the EP-1 and had issues.
The EP-1 works fine with other pedals like the H9.
