  • VEP 5, Dim Strings , Pops and Cracks

    Hi all,


    I have recently bought VEP5. I have created a template for all my Strings.

    My DAW is Pro Tools.

    However during a passage, all my Dimension strings are playing legato, which means there are 32 tracks playing legato.

    On VIP, I can see than there is nearly 600 voices playing together and cracks and pops are appearing during the passage.

    Is there any way to get rid of them. 

    I got an Imac with 32gig of ram and a Thunderbolt external hard drive.

    Thanks a lot

  • Hi Hicks, 

    600 voices is a lot. Did you try to change the audio engine settings in VI PRO yet?

    Also, are you using an SSD drive there?

  • Hi Paul,

    Yes I have changes the audio engine setup.

    But yes 600 voices seems quite a lot and I was a bit surprised.


    Do you think this is normal when all Dim strings are playing legato, or am I doing something wrong ?

    I made a test.

    I have loaded the VSL solo violin legato patch and played fast  a simple line (G to C and back to G). VIP counts 4 to 8 voices.

    Second, I have loaded the 1rst Dim violin legato patch (regular) and played the same line. VIP counts 20 to 32 voices.

    That's really strange.

    I am not changing the velocity and MirX is enabled.

    Thanks for your help

  • Hi, 

    Is Velocity Xfade enabled (that multiplies the voice count => all velocities and Release Samples are preloaded for each played note)?

  • Yes,

    it's enabled and I guess Dim Strings have 4 vel layers and solo string 2, so it would explain the difference.

    Same for the release.

    So having 600 voices simultanously seems correct when all strings are playing legato (with velocity crossdaded enable).

    And I have not yet added winds.

    Do you have any idea in order to avoid thoses cracks ?



  • Hi Hicks, 

    I´d deactivate Vel Xfade for the Dimension Strings in such a setup (or really only enable it when absolutely necessary, it is automatable) - alternatively, you could run the Dimension Strings on a separate fast computer. 

    Avoiding the cracks can also be achieved by increasing the network latency in the VE PRO plug-in and the latency of your soundcard.
