Sandi,
I can only explain to you procedur haw to change groove drums.
Go to Style view and pres F2 (Grove)
If you want to change that drums pres F2 again
and you can see Grove caracters change to Groove bank.
With Alfa deal knobe you can fined your desire
percusions.
If you press F2 again,caracters change to Drum2.Once again with Alfa deal knob fined your Drums.That is procedur haw to change.
If that work and you can change Drums all works fine.If dont,then is something wrong with your Audya.
Let me know haw its work for you...and please upload your Email adress cos I would like to talk with you.Deal?
