Some good points in this thread - thanks guys.
I use Maschine and Ableton, for the record.
One of the things that sucks about Maschine, is the limited functionality for layering drums. I was hoping that the Battery 4 update would integrate with Maschine in such a way to be able to independently effect (EQ/saturation etc) multiple layers on a single drum pad.
So - in summary - the only real advantages that Battery has over Drum Racks are the articulations/humanising functions and the actual library of sounds - which, if I upgrade to K9 or Battery 4, will browsable directly from Maschine.
So...really the only advantage is the articulations - right? (ie. flams, snare rolls etc)
Also, don't most (all?) 'real' sampled kits in Battery have velocity sensitve multi-samples? (To my knowledge, this cannot be done in Drum Racks - correct me if I'm wrong)
(some of the other humanisation can effectively be achieved through Grooves in Live, right?)
