Do the Yamaha's have the same as the Roland system for intros? That is, there is one simple count-off intro, one intro with no lead, one intro with a lead, and, most usefully (except for the straight count-off/short intro) is an intro that responds to chord input..

Those, IMO are the most useful. No preset changes, just the rhythms and pickups preset. You can get a LOT of mileage out of those without it gets repetitive....
