  • VEP and Digital Performer Offline Bounce Problem

    Hello.  I posted this in the MAS plugin thread, but it didn't seem to get any notice, so I'll try giving it a new topic here.   I have found a problem with offline bouncing that is consistent with every test I've run.   When using a single instance of VEP (MAS version) hosted in DP 9, I have 24 pairs of stereo audio coming in to AUX channels.   My VEP template has one instance with several Kontakt and Omnisphere plugins, each going to a seperate output pair.  When using offline bouncing in DP, only outputs 1 & 2 will bounce on the grid.  Every other pair is consistently late and behind the grid.  Normal playback is fine, and spot on with a click, but for printing stems, this timing error is a big problem for me.  

    This is a screenshot of a simple test I ran.  I have one midi track in DP playing quarter note clicks through a VEP hosted Kontakt plugin.  When the plugin is set to use outputs 1&2, it bounces offline and can be re-imported to see the click right on the grid.   If I change the Kontakt plugin to use outputs 17 & 18 (or any other random pair), it can be reimported and shows a latency of 1514 samples.

    So, I can't figure out a way around this, unless I use a single output pair from VEP, but that doesn't help much for mixing in DP.  Does anyone here have any ideas?  

    Thanks!

  • Hi Greg,

    May I ask how many buffers of latency the VE Pro plug-in is set to and what the buffer size of your audio card is set to?


  • Hello Karel.   My buffer is set to 520 in Digital Performer.   I have the plugin running at 3 Buffers.  That seems to be the best setting for my large template. when playing back a cue.   I've run the click offline bounce test using 0, 1, 2, 3, and 4 buffers in the plugin.   Even at 0, there is still some lag in all outputs (except 1 & 2) behind where the offline bounce is using Outputs 1 & 2.  It's like DP does not recognize the latency and compensate for it when using any output other than 1 & 2, regardless of the buffer settings.


  • Hi Tripi, 

    Please make sure that you have deactivated Pre-Gen Mode in the Audio Plug-In real-time preferences in DP (set it to "Virtual Instruments in Real-time" or "All plug-ins in Real-time", depending on the DP version you are using, instead!)

    Does that help?

    Best, 
    Paul

  • Thank you Paul, but I already have those options selected.   I've never used Pre-gen mode with VEP.   Any other ideas?


  • Hi Tripi, 

    Please send the song as a zip file to support@vsl.co.at, I´ll see what I can find out. 

    Best,

  • Thank you for offering to help.   I'll try to put together an example of what is happening and email it.


  • For anyone interested, Vienna support confirmed this bug, and confirmed that it is a DP issue (not an issue with VEP).
