Analogue-sequencer

I played a fun little gig over the weekend, a Parents
Coffeehouse/Talent Show for the parents at my daughters school. I
mainly set up my PA and ran sound for about 20 very talented
performers who mostly sang, played various acoustic instruments
(guitars, harmonicas, flutes, tribal drums,  digeradoo, piano). My
musical contribution was to provide ambient drums'n'bass prior to the
show and during the intermission.

I used my P3 with my Nova and ER-1, plus my newly acquired Emu
Morpheus. I initialized a bank and started recording into patterns
(edit-pattern, record) using my ReMOTE25, doing the MIDI looper thang.
Worked great. 

I found myself filling up patterns across all 8 tracks and wanting to
selectively erase an entire pattern/track, in order to either thin
things back out, or take things in a new direction, or just to keep
evolving what I was jamming with. 

Is there an easy way to clear out a pattern/track while the pattern is
running?
