RE Peter Erskine, I have the set. It is extremely well recorded, and the brushes will probably five you what you want. But if you want the PATTERNS or loops, they are VERY limited. I find not enough of ANY tempo to construct a proper drum track.
Also, the kits are mapped non-standard. There are a couple of GM \'sets\' that qualify as cocktail sets, I guess, but need major editing to be a playable full-on set (the drums themselves ARE there, and can eventually be mapped into a great-sounding kit, but it\'s a LOT of work, especially if you\'re new to the Giga editor.
