I bought this last year whilst I was recording my album. My friend who is a professional producer was doing the mixes and mastering recomended it to me during the project and I'm glad I got it. It's cheap and the drums are very good, particularly the additional packs you can add to the software to increase your kits.
I'm quite lazy when it comes to midi programing, which is where this comes in handy, as it has hundreds of fills, groves etc in the software which you just drag and drop into you sequencer (mine being cubase)
Otherwise you can just link it to a midi device and tap out the rhythm you want.
Anyway, to help anyone interested in this you can hear this product on my music on myspace under darrendcolvin on the songs Chambers of Hell, Christmas Lights and Musical Interlude.
It's used throughout my album Sojourn and for me was a Godsend in getting the project completed.
