    I am having latency problems running VEP 5 and Pro Tools 10 hd.

    Problem:

    The latency is considerable. At the lowest buffer settings I can uncomfortably work through midi programming although there are a lot of pops and clicks. The latency is to great for tracking audio in the same session. The delay is around 300 samples with Pro Tools delay compensation turned off and actually INCREASES to about 1400 with delay compensation turned on*. I thought VEP worked with delay compensation. Any thoughts? My last thing to try is to move all sound libraries to a dedicated 7200 rpm internal drive. I hope this helps with the pops and clicks but don't think it will help with the latency problems.

    Could sure use some help getting this working better

    VEP settings are:

    Buffer = 0

    Threads = 4

    midi ports = 48

    audio outputs = 58

    audio inputs = 2

    Pro Tools playback engine settings are:

    H/W Buffer = 512

    host processors = 6 processors

    CPU usage = 95%

    delay compensation = long*

    cache size = 512

    Plu in buffer = Level 0

    System specs:

    3.2 Ghz Quad Core Intel Xeon

    32 GB 1066 DDR3 Ram

    192 and digital 192

    VEP running on this machine, no slave

    2 instances in 64 bit mode

    Primarily running Kontakt Based plug ins (LASS, Damage, Kontakt factory, Berlin Piano etc)

    I AM SORRY ABOUT THE FORMATTING OF THIS POST, I GUESS THIS SYSTEM DOES NOT ALLOW FOR PARAGRAPHS.

    Hi PTrust,

    To allow paragraphs, please go to the "Community" Tab in your Community Profile and set the "Content Editor" to => Enhanced.

    For PT 7-10:

    There is one crucial setting you should adjust in Pro Tools itself:

    Please select Setup/Playback Engine and set the number of Host (RTAS) Processors to at least one less than your computer is actually equipped with, as well as CPU Usage Limit to 90%.

    Best,

    Hi bcslaam, 

    In PT 11 it´s only important to make sure that you have activated Dynamic Plug-in Processing in Setup/Playback Engine!

    Hi - this is very similar to my setup except that I'm working PT 12.

    Have you been able to resolve this latency issue??

     Thanks!
