Horned Band Filter - Just made it earlier. BP/BR with peaks at the edges rather than the center. Expanded look in topic.
(The attachment below has some fluff removed. Dunno about further optimization. Also hope the silly component module names aren't a problem. :v If anything is, it can just be reverted to default.)
There's also Slack Panner, but it's broken right now. Seems a Sound2Ctl bug might be the culprit? (Posted under Bugs)
EDIT: That was fixed quickly!
Here's that then, improved. Simple L/R hard-panning switch, plus controllers to adjust panning speed, minimum channel volumes, and activation delays for the signals that fade channels in or out.
Update to V4 further down.
Mirrored LR Peaks. Basically a widening EQ. Four pairs of peak filters, L and R are routed into the inverse of the other's peaks.
