Reprogram XPC8F attached to Alias8?

Trying to reprogram the 8 faders on an XPC8F tethered (correctly) to an Alias8, using the Livid Editor. The controllers need to be CC28-35.


The Alias8 refuses to respond to the following sysex, which should be correct - according to the OhmRGB documentation:
F0 00 01 61 07 21 1C 00 1D 00 1E 00 1F 00 20 00 21 00 22 00 23 00 F7

But this code may not apply, or any such adjustment be possible using the Alias8 as "host." Does anyone know?

  • Hi Art,

    I can help you with this.

    Yes, that message does not work on the Alias8, 
    because all of the Analog Mappings are included in message 10 (0x0A).

    Here's is a full message of message 10 (default settings).
     [240, 0, 1, 97, 11, 10, 1, 0, 2, 0, 3, 0, 4, 0, 5, 0, 6, 0, 7, 0, 8, 0, 9, 0, 10, 0, 11, 0, 12, 0, 13, 0, 14, 0, 15, 0, 16, 0, 17, 0, 18, 0, 19, 0, 20, 0, 21, 0, 22, 0, 23, 0, 24, 0, 25, 0, 26, 0, 27, 0, 28, 0, 29, 0, 30, 0, 31, 0, 32, 0, 33, 0, 34, 0, 35, 0, 36, 0, 37, 0, 38, 0, 39, 0, 40, 0, 41, 0, 42, 0, 247]

    I'm not sure which expansion port you are using, but
    specifically,  the last 16 pairs of bytes should match your mappings.


    To request the current settings you can also send this message:
    [240, 0, 1, 97, 11, 7, 10, 0, 0, 247]
    (which should help you determine where your updated mappings should go.

    Please let me know where you found the reference to that message that does not exist on Alias8, and I will patch up the documentation.

  • PS. Please excuse me for using decimal when you used hex.

    If you are having trouble and need hex versions of the commands for the software that you are using, let me know, and I'll post them.

  • @Moon -


    Thanks so much for your excellent guidance. From your instructions, I was able to figure out everything.

    As mentioned above, I got my (inappropriate) information from the online OhmRGB documentation - the only source of sysex guidance for any Livid controller (relating to programming expansion units) that I could find.

    FYI, there is one extra byte pair at the end of the complete sysex that does not relate to the expander ports; have no idea what it might do.

    FWIW, here is my complete sysex; it programs the Alias8 faders/knobs from bottom up, to CC20-43, with Master at CC7. Also *both* expander slots to CC28-35 (this way I can use either one I choose).

    240, 0, 1, 97, 11, 10, 36, 0, 37, 0, 38, 0, 39, 0, 40, 0, 41, 0, 42, 0, 43, 0, 28, 0, 29, 0, 30, 0, 31, 0, 32, 0, 33, 0, 34, 0, 35, 0, 20, 0, 21, 0, 22, 0, 23, 0, 24, 0, 25, 0, 26, 0, 27, 0, 7, 0, 28, 0, 29, 0, 30, 0, 31, 0, 32, 0, 33, 0, 34, 0, 35, 0, 28, 0, 29, 0, 30, 0, 31, 0, 32, 0, 33, 0, 34, 0, 35, 0, 42, 0, 247

    Thanks again for your help.

    P.S. I did file off the tab on one end of the XPC expansion cable to reverse insertion on that end. It might be helpful for all this info to be posted in the documentation for the Alias8 and perhaps also that of the relevant expander boxes.
  • Thanks Art!
