I can't believe Fran hasen't told you all this yet ! The lowly 2100 can substitute ANY rhythm pattern for an existing drum track from a sequence...just like the ..... what was it again....hmmmm ....SD-something-or-other (SD1)

If you're doing a song that has weird program changes (dog bark, hand clap) - MUTE the drum track(#10) and turn on the appropriate rhythm style. VOILA ! Perfect sync...perfect timing.

Pretty cool. Does the 2000 and/or the Tyros do this?
