Full disclosure: I work for FXpansion.
But try BFD3 and the BFD Oblivion expansion pack. I was part of the team who recorded the pack (I tuned, played the drums, and engineered one of the processed kits!) - we were aiming it at prog-metal type stuff, and I'm a *massive* Tool fan (keep the jokes to yourselves!)
Thanks for the heads up. I've done a bit of searching. Do you have any links to videos showing how the rudiments tool works? I'd like to see the work flow and sequencer in progress too. Sounds really cool.
In BFD3, you can program beats very easily, in any time signature you like, and we have a groove library which you can edit to your hearts content and then drag to your DAW as audio or midi.
There is also a cool feature in the groove editor called the rudiment tool - great for creating fills and polyrhythmic stuff!
