I prefer general styles, unless there is a song that has specific drum beat.But, for regular let's say 8 beat song I would always go for general 8 beat style.I still prefer playing as much as I can ..
I also don't want to sound that close to the original.What is the point then playing it live.
I do a lot of fixing to the styles I use.Basically every style in my keyboard I will change something.With T5 I always start with drums, and I go from there.
I don't make styles myself.I don't have time or will to do it from scratch.
