I'll agree, non-limiting, but you'd need an external mixer to complete the
effect I discribed. Nothing at all wrong with that If you want your Poly to
be a near-modular, but I'm trying to keep gear to a minimum. I have a
tendancy to play live on occasion.

Did that a while ago, except I forgot the switch. No click for me, hah.

Is there any noticable difference between the left and right line outs?
Positive and negative feedback sound different when the chorus is used
as a flanger, there might be something with this as well.
