No brainer for Stylus RMX owners

If you own RMX but don't have the expansion libraries, don't bother reading the rest of this review, just order it. Considering each library used to sell for, what, a hundred bucks a piece, this is a no brainer purchase. Sounds are typical high level Spectrasonics quality, and the 5 sets cover a lot of material, including acoustic drums which RMX didn't have a lot of. Like RMX the expansions are very inspiring, and you will find yourself wondering why you should bother to use any other drum libraries. There's a generous sampling of other Spectrasonics sample sets included as extras on the discs, as well. All in all, a nice update to an already excellent product.
