  • Cannot Get MIR working in Logic Pro 9


    I need some support getting MIR demo up and running.  I am ALMOST there, I think...just need to probably tweak my MIDI settings a bit.  (I am so-so on technical stuff.)

    Thanks for looking at this!


    • Instruments set up in MIR in Logic do not play back correctly.  One channel plays the other track's part


    • Can hear violin playing, but it's playing the harp part
    • Cannot hear the cello playing, except when I switch to that track in VEP5 and play from MIDI keyboard, otherwise it does not play back MIDI data inside Logic's Region 
    • Cannot hear Harp, except when I go into the Kontakt and play on the keyboard in its interface, otherwise it does not play MIDI region data (silence)


    • Downloaded VEP5/MIR demo onto my MacBook Pro and got eLicencer to work (finally!  Oh, the pain...the pain...)[:'(]
    • Downloaded and installed Demo MIR Room
    • Read the manual through several times, watched the VEP5 tour where Paul sets up VEP in Logic.
    • Started VEP5 Server (32 Bit)
    • Launched Logic
    • Instantiated VEP5 on a multi timbral channel
    • Connected VEP5 to server instance
    • Created 3 multi timbral channels and renamed (Violin, Cello and Harp)
    • Instantiated Audio Event Input thing
    • Connnected Audio Event Input thing to server instance
    • Inserted I/O utility on one of the new mult timbral channels, set the output to 1-2 (MainOut)
    • Bypassed the I/O utlity
    • Put some MIDI regions on each of the new channels (Violin, Cello and Harp)
    • Got MIR to find and load the demo hall
    • Opened MIR and set up VI instance for Violin and another one for Cello
    • Set up Kontakt for Harp inside MIR
    • Arranged the audio icons on the stage the way they would be in performance
    • Went to VEP5 mixer and set Violin to "ALL" (Omni) and to go out on MIDI channel 1
    • Set Cello to "ALL" and go out on MIDI channel 2
    • Set Harp to MIDI Channel 3 
    • Hit PLAY on transport
    • Set instruments to all different MIDI channels and stuff trying to get something else to happen

  • Hi,

    first of all: Is there any special reason you are running the 32-Bit instead of the 64-bit VEP5 server? You should consider running Logic and the VEP5 server in 64-bit to access all your available RAM.

    Second: In your setup I don't see any reason to instantiate that "Audio Event Input thing" at all at the moment. You should be fine with your instantiated VEP5 server on the multitimbral channel(s). In this case you don't need that I/O utility thingy either.

    Running one VEP5 instance should make your setup a bit clearer. The reason your Harp isn't playing on channel 3: I suppose you set the channel to 3 in VEP5 but you probably forgot to set the channel to 3 in your actual Kontakt instance itself (in the interface where you are also able to play the Harp directly on the interface-keyboard) ;)

    Please assign one dedicated Port and one dedicated MIDI Channel to each VI. "Omni" and "All" won't do! Make sure that the respective MIDI tracks in your sequencer use the same settings.

    This should do the trick. 😊

  • Hi Dietz and Marco,

    Got it finally!  Thanks for your help.  I went back from scratch and re-built the entire structure again.  

    Feedback from an idiot...documentation needs to be MORE specific.  Much much more detail needed for the non-techies in the world.

    Great product once it's up and running, though...really sounds great and is wonderfully controllable.

  • Hi Eric,

    good to hear you're up and running. Thanks for the friendly feedback!

    I understand your input regarding the manual, but IMHO it is beyond the scope of a professional's product manual to cover the subtleties of MIDI and the like, too. There are so many online-resources available nowadays that this seems to be a bit redundant. BTW: My colleagues here at VSL always ask me to make _shorter_ manuals, not longer ones. :-)

    Kind regards,
