I\'m getting weird audio breakups when i get to a high voice count w/ giga. i previously thought it was a problem with my new IDE controller, but i think i\'ve eliminated that as the cause. I installed a drive on the secondary IDE channel with nothing else on it but a few .gigs to test, and i still get the same problem, although at a higher voice count. same thing with the C drive, but at a lower voice count (104).
THE PROBLEM: when i get to a certain voice threshold (say 120 voices) the new notes cease sounding, and previously played notes begin \"winking\" in and out. for lack of a better description, it sounds like the drive is trying to keep up with streaming all the voices, and can only keep a few going at any given time. this gradually improves as the voices peter out. the sound is not unlike some excessively \"modern\" composition (think 12-tone), and does not seem like the sound of voices being dropped. there is also a weird \"electronic\" edge to the sound. interestingly, the voice meter freezes at the point where this happens, and won\'t indicate more voices sounding (despite more keys being pressed).
i have 2 other giga systems that do not have this problem, even when maxing out their polyphony.
SOLUTIONS I\'VE TRIED: AFAIK, i have applied all the recommended performance tweaks (UDMA, etc). i believe i have eliminated possible IRQ conflicts, but i\'m still moving things around trying to cover all the variables.
DOES ANYBODY HAVE ANY IDEA WHAT THE PROBLEM COULD BE?!?!?
i would greatly appreciate anyone\'s suggestions, especially if this sounds like something you\'ve experience and solved.
