Yamaha styles are very well programmed.
If you ask me, they should make those audio styles more universal..They are good but most of them too specific for some songs.It's a waste of space.
What i wish that Yamaha would do is give some new epansions for new drum kits..And they need to be much better.Yamaha should step up with drum sounds the way they do with other sounds on keyboard.My las Yamaha was 9000pro and I can't believe the drum sounds have not change since then.And when was 9000 pro made.

If they make new drums they could surpass Aydia styles easily.

With their new sound creator coming up they should make a good drum mixer for easier editing of styles.Sometimes we just need to tone downs high hats,or snare,or add some plate reverb on snare for a ballad style.Sometimes there is no need to edit whole drum kit.Just an element in a style..

We really don't need audio drums.
