Here's an article I just found, by a composer who prefers to conduct his recordings with live orchestra.
The author compares the cost and time and logistics of live recording as opposed to using computer-generated sounds. Surprisingly he finds a few dozen warm bodies scraping and blowing in a studio cheaper than a small team processing all the sounds synthetically.
Can any GPO user who's worked with orchestras comment on this? I found the page because I was curious about the cost and logistics of orchestral recording.
Those of you interested in commercial composition should browse around that site, if you don't already know it. Not my scene, but looks like a very useful central source if you like music for computer games.
