Problems with high polyphony

[Damian Smith]

I\'m having problems with GigaStudio. My setup is as follows:

Pentium III 866 Mhz system running Win 98 SE
ST Audio C-Port
512 MB RAM
Three 9GB SCSI drives, one partitioned for system and audio and two others for GS libraries.

The problem I\'m having is this. When I\'m playing a piece that has high numbers of polyphony, two things can happen.

1. I hear random notes from random instruments.
2. I get an \"illegal operation\" dialog. When that happens, the computer completely locks up and a blue screen appears.

What should I do about this?

Would it help greatly to switch to Win XP once mult8iclient drivers are available for the C-Port?

I can\'t say I had the same problem you have, but it was very similar.

I got GSt160 working great under W98SE, P3-750, 512Mb RAM. 160 voices, no problem. Yet with the same machine, XP Pro, I got problem over 70 or 80 voices. Allan from Tascam called it \"hanging notes\", and it sounds very much like what you said in situation 1.

I then tried it in my other PC, XP Pro too, but Dual P3-1G, 2G RAM. 160 voices. No problem.

Therefore I wouldn\'t suggest you go XP, as it needs more PC resource than 98.

Hi Damien
I have a setup very similar to yours, except for
the SCSI:

1 Ghz Pentium III (DELL)
40 Gb IDE 100
C-Port
Win98SE

I get > 140 voices without bluescreens or random
notes. I do get some popping at times though.
But I do get system crashes some times, with
errors like \'An illegal operation occured in the
... of a driver\'
These normally does\'nt happen during playing, but more during operations with the Gigastudio, Gigaeditor or sequencer.

Are you running Giga on a dedicated PC or do you
run Giga + sequencer on the same machine?

It\'s on the same system. I\'m running it with Logic Platinum 4.8.

Would it be a good idea to upgrade to a Pentium III 1 Gigahertz?

na, don\'t think it will make much of a difference.

Something you should check is the MultiTrack
Wave Driver in the DSP24 audio settings.
I used to have all sorts of problems when
running \'Single-in-sync\' - switch to \'Independent\'
if its not already.
