  • Issues with voice count in VEPro 5

    Hi there,

    I have a secondary system I use as a backup. It has two Vienna slaves driven from a main daw machine (cubase).
    I'm getting weird audio breakup/clicks/pops.

    The slaves are i5-3450 with 32 gig of ram each. The samples are on an SSD raid array of two drives. If load up my template, it all loads fine, but one of the two machines, if I pick an instrument that individually can pull a high voice count quite easily, I can crap it out at around 300-400 voices. For example, if I select the Spitfire harp, and play lots of big glissandi, the voice count gets up to 300-400 pretty easily. But 300-400 voices seems like it shouldn't tax the system too much, especially if the drive has no issues and the network usage is barely anything, so I can't quite understand why it is crapping out.

    What I am noticing is the CPU on the one Vienna Ensemble instance is what is maxing out. The cpu in total isn't maxing out, just the one core, and I guess that's because one instrument in kontakt within an instance of vepro is assigned to one core. I'm currently set to two threads per instance, but going up to four doesn't seem to change anything.

    If I use latencymon it does flag one thing - the RAID driver from intel. I don't know if that is the problem, since the disk usage isn't the issue, but the driver flagged is IastorV.sys - however, I'm thinking this is likely not the issue. Since it is a socket 1150, and I'm hitting the limit of what one core on the cpu can do, would there be any merit to swapping out the i5-3450 for a 4770k or a single xeon e3-1290 (both of which I can obtain pretty cheaply?) as a quick upgrade? Wondering what sort of improvement that would give...

    Any ideas?

    thanks!
