I’ve just set this up, using a USB Uno ‘all in one’ MIDI cable, works well for me…
in the setup button, remote tab, you’ve got to tell the console to listen to MIDI from the MIDI input on the back (vs card, or RTP MIDI)
then in QLab build a regular MIDI Cue pointing to your MIDI interface, using a program change, channel 2, and your snippet number as the program number.
I’ve got the console in snippet mode as well.
I believe if the MIDI channel is 1, it’ll change scenes, but I haven’t tried that yet.
You’ve not mentioned what version of QLab you’re running, but this works for 2.3.9 I can’t see why it wouldn’t in QLab 3 as well.
(I haven’t tested OSC in QLab 3 yet as this space doesn’t have that version available, but it should work also.)
I don’t actually see a “Go” command via MIDI.
Thanks!
