I'll have a look at what you suggest for the midi stuff. I thought this would be a no-brainer - just read in a source file, configure it to 'transpose to G# please' and out plunks a midi file in G#.
Thanks for following up - I too got L8 loaded on my G4 and everything is 'pretty good'. 70% of my workflow is unhindered, however, I do see small wait times when loading/searching loops, or instantiating a 'heavy' AU like Stylus. Other than that, I refuse to whine about L8 performance. On the graphics side of things, I _would_ like to see the bottom transport bar to be removable and some changes made to floating windows (how about a floating window, with all the menus?) but that's no big deal.
You're absolutely right about content - my space is at a premium too - my 93 gb drive is about 93% full :). I'll work on that when I'm bored some day in an airport.
