The studio that I've used Native Instruments Maschine on is Pro Tools HD based, but also has Logic Pro. The producer who owns the studio uses it in both DAW's, while the computer being used is a G5 desktop that's more than capable of handling a lot of tasks at once. Definitely make sure you have a pretty strong system before purchasing Maschine if you want to use it to it's full capacity.
Native Instruments' Maschine is definitely up there with the best, if not the best, groove production pieces of software that I've used. When paired with the in depth and very helpful MIDI controller, you've never had more control over making your beats. There are literally no restrictions with this - only your imagination. Unfortunately Maschine has to purchased individually and isn't included with Komplete or anything like that, but even so it's certainly worth a good look at for anyone making music with your DAW. With more and more people doing everything in the box, Maschine (or something or comparable quality) is becoming highly necessary to have in any working studio environment.
