I have Live configured the same way I’ve always had Live configured - the same is true for the other pieces of hardware. They all “start” when I hit the appropriate button for any other master source. Just not the Denon X1800.
I’m open to suggestions I’ve missed, but so far no help from the Denon folks has arrived. Even if we figure out the workaround, the X1800 is supposed to send a “start” command when you hit the MIDI button and it seems to not be doing so.
Thanks for the help.
