I'll see if I can recreate it...
EDIT: You know what? I'm playing with it now and it looks like different "types" take up more or less DSP. I'm sure I saw it go silent and give me the warning sign at 72% or so, but I could be wrong. Maybe there were some settings that were at 72% and I changed the type, assuming they were all the same, and the next type used 8 delays and kicked the thing into way too high of DSP usage. Sorry, I wish I would have saved the original preset to fiddle with
I'm just hoping it's user error.
