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 v3.1.
When i use several audio parts and plug ins along with some midi parts ( vst performance reach half of the bar) and sync my roland tb 303 via a kenton or the dyn sync of the novation drum station i have the following problem : midi clock isn't stable at all , it's like if the notes of the 303 weren't quantized.
By the way when i create a blank new song with no audio or midi, sync it's perfect!!
I've tried several settings and different midi ports to send midi clock but i couldn't solve the problem.
I have to say that also simple midi parts don't follow perfect timing but it's not as bad as the sync problem.
Is this a bug of vst?
does anybody have any suggestion ?
