I should make you guys a sample or two of the p600's poly-mod. It can be
fantastic. Here's a loose quote from the manual.."provides routings within 
each voice for the filter eg or osc b, to modulate osc a or filter cutoff. 
Although the routings are exactly the same for each voice the result will
be different, for example each osc b source will be at a different freq.
This
is in direct contrast to lfo-mod where one signal is applied to all voices,
yielding the same effect from note to note." What this means is all kinds
of bazarre sweeps, ring-mod effects, bells, percussion, klangie stuff
that's
completely out of control most of the time. Loads of fun! a sample or two 
wouldn't do it justice.
