Following a posting on osxaudio regarding problems with EXS, I decided
to do a test of EXS' polyphony:
a) I call up three instruments: Malmsjo piano, Wizoo piano, Peter
Ewers' symphonic organ (all because they have individual samples for
every key, and they're stereo), and gave them 48-notes of polyphony
b) I made a 48-note chord that lasted 4 bars (quantized so all notes
fall on beat 1, bar 1), and cycled the first 5 bars
c) copied the chord to all three instruments, and hit play (that's 144
notes, if you're counting!)
d) after hitting start and stop a few times, with time in between, not
fast, I started to get drop-outs in 1 out of 3 of the instruments
e) eventually, I would hear drop-outs even on a single solo-ed
instrument
f) I went to the virtual memory panel, changed a few settings (slower
drive, hard-disk activity less) and hit the 'apply' button
g) Logic crashed
h) I repeated this after re-booting, just to be sure, and exactly the
same things happened (crash)
My questions are: what about the 1,000 voices from the G5 unveiling?
How about just 150, without drop-outs/crackles? Is this related to my
use of the factory drive, as opposed to using another, audio-dedicated
drive? Can anyone confirm any of this?
Here's my setup: G5 Dual/2gig ram + Panther + Logic 6.3.1 + internal
160 gig factory drive.
Thanks for any feedback!
