If your sample db is ridiculiously large (whose isn't?), you'll need this beauty just to have a very smart browser for your drumsounds.

The sequencer is a nice enough cherry on top. It is usable for quick scetches and you can very easily listen to the compability of your chosen sample-pack and super-easily swap single samples with similar sounding samples or listen to your rhythm with complete different sets of samples.

Drag and drop your achievments to stems or take your single samples and take the programming of the rhythm to the next level in the plugin of your liking.

This has become one of the most heavily used tools in my environment.
