  • Vienna Ensemble Pro: Multiple Slaves in Cubase 6

    This may be a really stupid question but neither reading the manual nor searching this forum resulted in solutions.

    I have four PC's: one master with Cubase6, three slaves with Vienna Ensemble Pro. All software versions on all systems are identical.

    An instance of Vienna Ensemble Pro Server is open on each slave system.

    I open a test project in Cubase (main system) and load Vienna Ensemble Pro into VST instruments.

    I connect to Slave 1, and it works: An instance of Vienna Ensemble Pro opens up on Slave1.

    Now, how do I connect Slaves 2 and 3 to Cubase?  On page 8 of the manual, it reads, "Each Server Interface can connect to 1 instance of Vienna Ensemble PRO, and of course you can utilize multiple Server Interfaces and instances!"

    So, I open another instance of the Server in VST Instruments.  When I ask it to connect to Slave2, I get this error message:

    "Could not connect to " SLAVE2 [32]" because the version numbers of master and slave do not match. Make sure that the same version of Vienna Ensemble Pro is installed on both master and slave systems."

    Connecting to Slave2 is no problem when I start this process from scratch, so it's not a problem with Slave2.

    Any help would be greatly appreciated.  Thanks!

  • Hello?  Was the question THAT bad?  I find myself having 3 external systems and only being able to use 1 of them.  Any help would be appreciated.  Thanks!

  • Just to clarify: Each Vienna Ensemble Pro Server instance on the Slaves can be accessed individually.  I just can't connect more than 1 at a time.  What am I doing wrong?  Thanks.

    Hello Edwin,

    The error message indicates that there is a version discrepancy.

    I´d uninstall the VE PRO Software and install the latest version of VE PRO and eLCC once again on all computers, just to be safe.

    When you start a VE PRO Server instance on all machines, you should see the IP addresses of all computers in your network as soon as you insert a VE PRO Server Interface Plug-in in Cubase.

  • Many thanks, Paul!  The versions are identical. The VE PRO Server plug-in works, in that it shows ALL 3 IP addresses.  The issue is not that the machines are not communicating and not seeing each other: they ARE showing up exactly the way they should.  The problem is that I can only connect to 1 slave per Cubase project.  I can connect to each one of the slaves separately, but if I open more than 1 instance of the VE PRO Server in Cubase, then I get that error message.  How can I make this work?  Thank you so much for your help!

  • Check the version numbers of both the VE Pro plugin and the VE Pro Server applications. You can see the version number of the plugin by clicking its title on the GUI (top part that says "Vienna Ensemble Pro Server Interface"). The application's version number is shown in the About window. Make sure that no plugin host is running when you're installing VE Pro to ensure that the plugin is properly replaced. Hope this helps.

  • All VE Pro Instances on Master and Slaves have been on version 4.1.8008 for more than a week now.  I just found out, though, that there were differences with the eLicenser versions.  So I installed the latest eLicenser on all 4 systems.  Now, everything works as it should.  I didn't know that the different versions of the eLicenser had that much power over how VE Pro would perform.  Lesson learned.  Your patience and help are highly appreciated!!!  THANK YOU!
