This isn't so much of a question but rather fishing for better solutions, but here's my setup...
I use GPO Studio exclusively with Sonar with each loaded on its own PC. Both PC's are fairly new and have plenty of HP. My sequencer/DAW doubles as my all-purpose computer. Obviously I cannot load an entire orchestra in memory with the complexity I'm looking for (i.e. lush strings, ensemble players, solo instruments, brass overlays, full percussion battery, with the piano and harp). I don't consider the disk streaming as an option though honestly I haven't tried it.
But at the same time, I want to be able to hear all the instruments as I work. So I came up with a full orchestra "lite" template which uses the low-memory Plr and lite versions of the instruments... This occupies about 30-40 MIDI channels with a little memory to spare (2GB total). When I go to record the full version, I have to record each section independantly (as much as my RAM will hold), and each section itself could use 10-30 channels depending on how many players and different sounds I need. So needless to say, even if they would load in memory, I still wouldn't have enough slots in GPO Studio to hold this setup.
I was wondering if anyone else has a similar setup. For doing these grand orchestral pieces, how do you split up the instruments to record them? Or do you even do that? I think I once read where DPDAN suggested recording by the actual sections of the orchestra so that you can apply different amounts of reverb for a more realistic sound. I liked that idea.
Just thought I throw that out there. Thanks and have a wonderful day!
