The trimpots on the main PCB shouldn't need to be adjusted to "work". If there are trimpots on your module, you need to adjust those first. If your module has a "bias" trimmer, adjust that first till you get the fullest sounding phase (make sure mix is set to 50% and depth is 100%). The optocoupler module has a "voice" trimmer. It's pretty subtle, but adjust it till has the vocal/vowel sound that you like.
The upper and lower limit trimmers are pretty interactive. You can set one where you like it and then it will get shifted when you adjust the other. These control the pedal's speed knob. I can only liken it to putting new strings on a floyd rose - you can tune the top E and then go through and tune all the other strings. By the time you get to the bottom E, the top E will be out of tune. You just have to keep repeating it till you reach a certain equilibrium. Hopefully, that makes sense.
There is only one upper limit trimmer for your expression pedal. This is because most expression pedals will have their own trimmer that controls the lower limit. You'll need to perform the same process for the expression pedal as you do for the speed knob.
Thanks Keith! I have the octocoupler installed and have experienced exactly what your were talking about! More about "trial and error" until you get the effect you are after. I did find a combo that I am very satisfied with! I have 3 other modules but I bet it's going to be hard to top the 'octo'.
Cheers!
