Oh, this is more like it! Back when I first played with Logic 8, I had to see what the Demo Content DVD included - a few example Logic projects from established artists, for folks to fiddle around with freely. Except, Hyzenthlay could only manage about the first five seconds of Shiny Toy Guns' "Le Disko" before withering. Frustrating, as it's fascinating to be able to see all the individual elements of real songs in this manner, be able to isolate each track, combine some subset, boost the level of some, and so on.
I finally dug up that disc last night, now Dandelion's in the house, to see how it fares with Logic.
Yep, no problem - all 69 tracks just played perfectly happily. While its video was playing in sync. And Screen Recording was capturing everything real-time in H.264. I think there's some leeway. =:)
