Ah I made a mistake with the switch values, it was a quick addition just to give the option of adding or removing the delay. Strangely, I hooked up a monitor and the switch still output 0 and 1 even though the values were not set, so I guess it actually doesn’t make a difference. The other weird thing is that even with the picodelay in the feedback path set to a delay of 0, the filter sounds more correct than with feedback straight from the output back into the crossin module. The order of the modules definitely matters as well. I still can’t get it to work right though.

Thanks for your help! I’ll check with support to see if there’s a solution.
