The most of the on board patterns are with live drums.
If you download the quick manual you can read a list of all the styles.
As i said before. The keyboard sounds great. The more i play on it the more i love it. The only thing that is annoying is the autorolls that sometimes does not roll in the right places. That was a pretty stupid ide from Ketron in my opinion. You should at least been able to turn it off, but u cant.
