Does ION offline accept MSC?

We don't support any 3rd party MIDI adapters, only Show Control Gateways and (of course) the console hardware.

Eos/Ion Offline does not have any interaction with gateways except the possibility of visualizer output of level data.  Show Control and I/O gateways communicate with online primary processors when correspondingly configured.

Combine this with Richard's answer and you see that offline does not listen to or transmit MIDI in any format.  Primary consoles provide the facility for that communication in networked systems.

Thanks for the speedy answer. It looks like I'll have to do without then since buying another console to take home and program shows isn't in the budget. At least I can put the queues in both systems and hope it doesn't require much effort to get working during load-in.
