Anyone here play a horn or guitar and uses their keyboard to sequence with the styles?

Please don't recommend a computer program. I have Cakewalk, I don't have time to sequence each bass, drum, piano horn section part etc., for each tune I want to do, and besides I rather many of the styles on my keyboard. I can't improve on them.

I go to the store and find the PSR2000 sounds better than I thought at first when I played it last year. Then I get the manual out and it seems that it won't copy and paste measures. This lack of copying and pasting measures makes it useless for sequencing to me.

I could convert my sequences to midi files to play on other keyboards but I would lose the effect of using all of the change on the fly functions I have on my keyboard which gives a more live effect.

Which of you floks have a keyboard that will copy and paste measurers and then copy and paste a whole chorus over and over to complete the tune.
