Yes.
I was working with Logic 9 this morning to do the bouncing one track at a time. I have a couple of pieces with no more than 10 instruments each, and it was very nice to use. I started with notating in Sib. 6, transferred to Logic 9, set up the Vienna instruments and/or Ensemble 3, and bounced from MIDI to Audio. All of my dynamics are in place from Sibelius, and now I have nice Audio tracks to work with. Enhancing the tracks with Logic's good reverb, and doing other mixing things is just great for me in Logic anyway. I dumped all the MIDI tracks and saved as 'bounced' file. I also saved just the MIDI version first, in case I need to deal with that. It's so easy to use now. In Logic 8 I never could do this kind of bounce, only the 'real-time' version would work for me.
I'm pretty new at any kind of bouncing of tracks, but it's very appealing to just open the music now, without having to open VE3 or VI first, after I've got the basic tracks they way I want.
I'm appreciating some of the 'little' things, like change of placement for menu items that makes more sense to me, and the new white outline to tell me what area is selected.
