I agree with Ed. I tried the laptop and sound module approach live and was not pleased. in one song there was just a 1/2 second lag at one piont in the song, I think due to the laptop, and it threw us live players off, and we had to adjust when we realized what happened. I now prefer an onboard sequencer in the keyboard to trigger my sequences. Much cleaner.
I use an XP-80 and an S90. both with onboard sequencers. I am considering add a sound module again to help with polyphony, but would still use the onboard seqs and not a pc/laptop.

Peace

PS. I do use a simple 8 channel mixer to blend my boards as well. Kept at arms distance.
