Really great product! Even with the default Kit and midi grooves, you can create a wide array of real drums. This is the future ladies and gentlemen - its not even fair to call it MIDI drums anymore -- this is REAL drums. The levels of detail and tweaking that has gone into building this product is second to none. One of my favorite 'little' big features - is the tap-to-find Midi search. It lets you tap out a simple beat or rhythm, and then it finds matching pieces of MIDI in your library that would go well with your beat. After you find this beat in your library - OR just go off your simple beat tapping, One more drag and drop, and you can use the automatic-song-creator to generate an entire song with intros, fills, verse and chorus. It makes song creation so much fun! I'm primarily a guitarist - and I can go from a riff on my guitar, to having a complete rough-draft of an entire song - literally in minutes! So you can get back to spending time just working on fun riffs and bits and not have to spend hours just trying to get a basic song done to keep working on other parts. After all this, you have complete control over which sounds and kits are used, and can individually tweak everything from the mic placement to the drum, to the room bleed. Lots of built-in plugins to aide in the mixing process as well - tape simulators, delays, and a full graphical EQ for each channel. Can't say enough nice things about this product - it's been a wonderful experience through and through.
