Hi Dan!
I rarely sequence, but when I do...it's usually for the kids at school. I use garage band on a mac, or reason if I need better sounds.
At home, I can sequence right in the PA80, but I don't have a need to. I don't consider using styles as sequencing either...even if you tweak them. In my book - a sequence is a note by note creation, and most of the ones I use are commercially available. Fran and I were Tune1000 dealers back in the day, and that's where most of my sequences come from.

I also utilize the arranger with backing harmonies to create personal live arrangements to record to MP3 format...then I play over them and sing lead. I think many cats do this.
Heh, heh .... "cats" .... I sound like a jazz guy that plays "gigs" now, huh?
