I think i remember seeing that You tube video when it was first on the TV. Jayzus i'm old
The question is, could you do anything on that monster that you couldn't do with a decent sampler, synth and hard disk recorder? Or even Pro Tools, much as i loathe Pro Tools.
Now, as a Logic user, i must say im not a fan of Protools, but sometimes, im forced to use (as much as i hate Digidesign and there crappy hardware ) as my workflow for audio editing is so much faster, but its crap for midi, Logic reigns supreme at midi
