Moving Beyond the "it just comes free with a music magazine" snobbery i think this drum machine holds it's own among VST instruments that claim to be virtual drum machines and end up being cpu killers an user frustrators. No unbelievable stuff, just does what it says on the box.
The thing to remember is that this is no complicated si-fi synthesizer/sampler/beat manipulator. It's a beat box. A sampling drum machine. 16 pads playing sixteen samples. You can tweak those samples beyond recognition, you can really customize the feel of how a drum kit plays and off you go. Make some drum tracks.
All the edit features are extremly useful and being able to edit the whole kit globally as well as indivisual sounds makes the kit sit very well together.
The best feature in my opinion is the way this VstI saves drumkits. All samples and edits are saved into a custom SR202 file and (miricale) when you load a song you were working on three weeks ago, the drum track won't need 30 minutes of tweeking to sound as it did the last time, nor wil you have to go searching your hard disk for sounds you have moved without permision of your too expensive-too clever-drum sampler-manipulator-beat creator.
A small touch that is gaining popularity with VSTis is the heavy knobs, i.e. knobs that don't fly around like crazy from the slightest mouse click.
Ofcourse some things are calling out for improvement though. There is no support for stereo wave files and samples above 44k are labeled bad files. Hmm.
