Now that's the first time I've seen a visual example where loading hundreds of midi tracks actually makes sense.

A composer who has such a huge library of orchestral sounds doesn't want to be distracted by constantly loading sounds to audition, he would want them always ready to play.
So... in theory it seems that both sides of the debate were right. Nobody *needs* 2-300 tracks to make a composition but boy - as shown in that video - it sure comes in handy in that situation to keep things moving along. Thanks Caveman.
I don't have enough system memory to pull that off anyway so it's moot to me. :

I wonder how many GB of instrument samples he has loaded there?
Now, where's the video where a guy has 500-999 audio tracks (or more) in one daw scoring a movie?
BTW, Is this Hans Zimmer scoring The Dark Knight with Cubendo?
