This can be confusing but maybe I can help. But I should let you know that I have done this before, but we have an Obsession II board so it's a little older but the principle should be the same.
First -- make sure your
Qlab has a device ID and that the 'use
midi show control' box is checked.
Second -- Make sure your
ION has
midi turned on. in the Obsession II it was in the I/O settings.
Third -- Configure your
ION to listen for the device ID of your
Qlab and set its own device ID. For instance, lets say your
Qlab is setup to be device ID 1 then you need to make sure that your board is listening for device ID 1. Then when you use the
Cue in
Qlab you'll have to set it to the device ID of the board (lets say 2).
That part is pretty easy.. now here is how you use the
MSC command. It might be different for the
ION than it was for the Obsession. but this should get you close.
In your
MSC cue go to the
midi show control message
tab.
Make sure your output device is correct. Then set your command format to Lighting (General). Set the command to GO (assuming you want a
cue to go). Set the Q number to the
Cue number you want to go. The
Cue list number correlates to the list running on the board. Most likely if you don't know what this is it's Q list 1. I honestly have no idea what Q path is but again I've had success setting it to 1.
If all the device IDs
line up and the board is configured to accept the command this should fire lighting
Cue X.
Now to take it a step further... we have a few boards at school. I've managed to make all of them talk to
Qlab with the
MSC function but with different results. On our Expression board i can take the
MSC command and leave the Q number blank but make sure the command is still GO and no matter what
Cue the board is on it will take the next
cue or
cue sequence. But on our Obsession board you have to put a
cue number in to tell it to fire a specific
Cue.
Hopefully this was coherent enough for someone to follow. Hope it helps!
