MC Control randoly selects tracks with Ext MIDI

    Hello!
    I am desperate. Euphonix say they cannot reproduce my problem and Apple doesn't care either.
    I can reproduce the issue with two different MC Controls on four different newly installed Macs.

    Issue:
    When using External MIDI tracks connected to multi-instruments and pressing i.e. play on the Control or any key on a MIDI keyboard, the MC Control randomly banks to different tracks.

    Steps to reproduce:
    1) Start Logic 8.0 to 9.1.1 in either 64bit or 32bit mode and have the Control switched on. Create a new project
    2) Create one Software Instrument track, uncheck multi-timbral
    3) Load any Audio Unit into this track, doesn't matter which.
    4) In the environment create a Mutlti-Instrument and activate all 16 channels. Cable it to the software-instrument
    5) In the Arrange create 16 External MIDI tracks (Track - New... - External MIDI). Make sure all tracks are assigned to the multi-instrument you just created.
    6) Repeat steps 2 to 5
    7) Save the project an ropen it
    8) Select any of the MIDI tracks and press play on the MC Control.
    The faders will randomly jump to 4 other tracks.

    The more multi-instruments you have in your project, the higher the number of times this happens. Instead of hitting play you can also press any key on a MIDI keyboard.

    I told Euphonix these steps, but they say the cannot reproduce it. I can on 4 macs with 2 different MC Controls.

    So please, of you have a MC Control (or a MC Mix, maybe it happens there, too): Please, please, please try it out!!! This bug makes working so difficult and Euphonix and Apple just deny the problem.

    Thanks!

    Thanks, Mark!
    Glad to hear that I am not (yet) gone insane and imagining bugs.

    Try to filter all midi messages in Logic and see if it helps.
