>>This is one I'm sure you'll have come across too, but as I've
recently acquired a Drumstation, I've been doing quite a lot of
x0x-type programming of percussion patterns.<<

you could, later, consolidate the multiple track data onto one or two
tracks set up to record polyphonic data, if track-use became an issue.
this assumes that you don't want to do too much more editing, of
course... but you could still fool around with switching auxes on &
off on individual steps to modify the drum parts while they are
playing. also, assuming you follow the "drummers have four limbs" rule
of programming (like I do!), you will have an aux left over for
masking events.....

never one to gloat or anything, but I use my octopus to write the drum
parts in grid fashion, then record them into the p3. :-)
