    I was wondering how the audio interface affects the performance of VEPro5 Server. Im running a macpro 8 core and 3 PC's in server mode  and it get's pretty maxed out. I have MOTU 2408 interfaces on the Mac. Would swapping to a more efficient system -  apparently like Apogee Symphony or maybe Protools -  reduce latency and give me more CPU headroom to run VEPro5 instances etc?

    I doubt you get many more tracks changing audio interface, you must look on the other part to your configuration, specialy with all you have

    What software are you using ?

    Can you give your full configuration ... memory, disks, buffer settings ....

    Digital Performer  + VSL EP5 loading VSL, Play and Kontakt 5.

    What interested me was that with a really big rig, the mac becomes the weakest link and running 4 VSL server instances plus dozens of inputs etc pushes everything to the edge of what DP on an 8 core Mac can manage. Lower latency systems like Apogee Symphony and Pro Tools that do more work on the PCI card I assume, and take the load off the internal processor but at a considerable price financially!

    I experimented with changing the buffer settings in the soundcard - MOTU 2408's seemed to effect VSL's internal latency from the servers and I'm not quite sure why. So I was wondering if running a really big rig using VSL Server using top line hardware like Apogee or PT's would provide a tighter more agile and stable system with lower latency.

    You did not mention your disks. Disk i/o and CPU  are the heavy part of VSL

    Since I have moved to raid 0 I have gain a lot.

    Very true - all my most used libraries are on SSDs and I run the projects off an SSD in the mac which eliminated a lot of problems recording large numbers of tracks at once. It was a bit of a leap of faith given how much they cost but worth it.

    did you change the buffer size in Directory managr

    That's a good question. I will have to do another test and really get to grips with what is going on.

    how many GB of mem ?

    did you monitor your system while playing heavy song ?

    Is the swap used ?

    Hi guys, i'm a little confused about this whole thing! I've compared server to physical i/o both in VEP5 and it seems that audio coming back from the physical audio is faster, meaning less latency! Last week, i got rid of Logic completely and since i had been using PT for years for audio and for mixing, i decided to attempt also using it for MIDI. So, with a TDM system, i believe all audio routing, bussing and i/o's are being handled from the TDM cards (or HDX for new systems), and since all audio is handled by the PCIe cards, in theory, they're should be less strain on the CPU! Of course, your host machine has to be able to handle a bunch of audio streams coming to it on its interface, but that's what PT is supposed to do well! In my early tests, so far, i can get a pretty fair amount of instances on a 12-core system, the slave machine being the 12-core and an old Harper Town 8-core running PT10 HD at this time. I'm running MIDI over Lan and so far, with VEP5 and mainly using VSL libraries and Kontakt, it's pretty good. When using Play, it was horrible... Probably will try hosting the Play stuff in my host PT Harper Town Mac Pro 2008 on a seperate VEP5 server.

    My plan is to pipe 64 mono tracks on 32 tracks from the 12-core from an SSL MADI Xtreme card to PT HD MADI. Right now, as i am testing and waiting for HDX system, running 24 stereo AES tracks from the SSL MADI SX to three 192 Digital interfaces.

    Cheers
