I haven't used Protools in a long time, and I miss it quite a bit. There is a reason why it is (was?) the professional platform of choice.

I never cared for Cubase, myself, but I haven't looked at it in several generations, either. Live offers some neat possibilities, but doesn't offer the depth of MIDI editing that Cubase does...not even close. Download the demo, and give it a try. You may find you like it, you may not; it really depends on the way you work.

(I swear by Live, myself, but I'm not doing complex MIDI work, either.)
