pulsar II v3.01 poroblems on mac

lore · Post by **lore** » Tue Jan 22, 2002 5:51 am

hello i have a mac g3 450 mhz(blu/white) 384 mo ram
ati rage128 ,scsi ultrawide pci card( for 2 segate barracuda hd),pulsar 2,scsi adaptec 2930 for cd-r, usb midisport 2+2 .
mac os 9.1 (upgraded from 9.04) ,oms 2.3.8.
Pulsar v3.0.1. and VST 32 .5.0(original)
For some reasons , too long to explain ..,i have to mix, compress.. everything in pulsar from now on (before i had hardware mixer) and it happens that after a few minutes that i'm tweeking some eq or effect into pulsar window ,while vst is running some midi and audio sequences, everything freezes leaving a VERY NASTY AUDIO LOOP. IT happens only when i'm working into pulsar window and not when i'm in vst's one.It's really impossible to work like this and restart the mac each 5 minutes.
Vst has 180 mega of ram and cpu is at 65%
pulsar app has 30 mo and dsps at 40%
The rest of available ram is for mac os which also manages pulsar's memory ,it floats between 85 and 95 mo depending on the size of the current pulsar project, thus leaving about 75 mo of ram free ! .
I've tried to increase and decrease memory allocations to the apps but nothing changes.
I think that the problem relies into asio which crashes and generates this nasty audio loop(like a looped very short sample going into feedback ): trrrrrrrrrrrrr.
PLEASE HELP me

on my g3 384mo ram i put 180mo for cubase and 55 mo for pulsar-Maybe it could be the ram(i hope).i have noticeed something strange when i have start on pulsar i tryed several ram config cause pulsar was crashing me lot(why?i don't know) since i have put 55 mo on pulsar app for me it is ok(under os 8.6-oms 2.3.6).i hope it is only that for you.
Another thing recently i put an old ultra wide pci card adaptec 2940 on my last pci slot to connect a HD seagate cheetah(a friend gives that to me cause he didn't use it for the moment)from that time my machine was always crashing(why?i don't know,maybe to much cards,but the hd name was appearing and deasappiring from my desktop!)after several nervous breakdown

i retire the pci card everything runs again at 100%
bye

Perhaps you should disable HD indexing in the Sherlock options? Or you have any antivirus apps running in the background? Or just any background operation takes place during your Pulsar session? Try to delete midi ins/outs for a rehearsal and watch the effects... Or just disable oms in Cubase.... Try oms 2.3.7 (it looks as it is the best for Pulsar). They say any scsi card could be a problem, too: try removing it from your computer...

They are just simple things that appeared in my mind but perhaps you forgot about one of them in your research... I hope one of them would be your remedy

well , i've disabled indexing ,antivirus and all the background stuff since the beginning:).
the only thing i can try is to remove the adaptec for the cdr but not the ultrawide one cause in only have scsi hds.
any way a computer has pci slots for pci cards so why should there be a problem?
OF course i am not complaining to you guys ,you're always there when i need help;
while at creamware they never told me useful tips ,once they said "try Logic audio it works better than vst with pulsar " !!!;(

thanks anyway
