  • VE Pro standalone, slight pops and crackles

     Hi all

    I have been using VE Pro (as a plugin) for over a month with stable and good results.  Recently I am attempting to run some bigger projects with VE Pro running as a standalone (and local) application, so as to avoid the horrendous long save time of Sonar [:P].  But then there are some occasional pops and crackles, even when there is one instruments loaded, or just playing a long sustained note.  It's not serious, exactly like what when you are playing a 80's vinyl record... but it's just there.  I am not sure where to troubleshoot, probably it's some stupid mistakes I made in the setup, though I have been running it very smoothly as a plugin.

    Here is my setup(s) :

    And BTW I am only running VE Pro as a local mixing host (on one computer that is), so the network feature isn't used.

    Computer : Dell Precision 3500 Xeon Quad-core 2.66GHz with HT enabled, 12GB RAM, MOTU 828mk3 FW audio interface, Windows 7 x64 Professional and Sonar 8 (x64), both 64-bit and 32-bit versions of VE Pro have been used (and tested) in both scenarios.

    Scenario 1 (running as a plugin where there is ZERO problem!) - Buffer size in 828mk3 and Sonar both = 256, VE Pro buffer = 1.  Have Kontakt 4, G-player, WIVI and the VSL Soprano Choir loading in 5 instances of VE Pro (server).  Biggest template so far is only 5GB RAM but it's running very very smoothly, as I have mentioned.

    Scenario 2 (running as a standalone application) - Using LoopBe30 to connect between Sonar and VE Pro.  Have tried changing buffer size (in all of the audio interface, Sonar as well as VE Pro standalone) to up to 1024 but that doesn't seem to change anything.  Tried both when audio out is lightpipe'd back to Sonar, or sending directly to main analog out, same result.  Now this is when even when I load one instrument, say Sop Choir sustain, and while playing that sustain note there are slight and occasional pops and crackles.  So probably it shouldn't be a polyphony, CPU load problem, I suppose?

    Any suggestions would be much appreciated!

    Thanks,

    Frankie


  •  I have solved this by setting the Multiprocessor support to OFF in Sonar, leaving only VE Pro (and Kontakt) running with multi-core support.

    Another question, is it supposed NOT to run both the x86 and x64 standalone together?  I am getting quite serious crackles if so.  'Course it's fine when I am only running either of the standalone.

    Thanks,

    Frankie


  • Hi Frankie,

    running 32-bit and 64-bit VE PRO instances simultaneously shouldn´t be a problem at all. Did you experiment with different buffer settings?

    It´s also important the the MIDI and Audio settings of all VE PRO instances in a network are identical.

    Hope that helps!

    Best,

  •  Hi Paul,

    Yes all instances of VE Pro are set to default, so I assume they are the same then?  (And I am talking about the standalone too).

    Anyway, I found out the culprit is Sonar again.  As long as Sonar is not running, VE Pro 64 & 32-bit are running fine side by side in standalone with crystal clear audio output.  I guess there must be something wrong in the audio setting (audio engine) in Sonar which I have yet to learn and discover.

    Thanks a lot anyway!
