Switching off outgoing MIDI

Hi everyone,

in our setup (main console is a Ti with v. and a Gio in Backup-Mode) we receive MSC and send raw MIDI via a ShowControl Gateway, which works fine. But sometimes you need to shut it off, both ways.

For not receiving any MSC it is enough to turn off MSC rx (with a macro) but not for sending MIDI to the sound department, as their program doesn‘t understand MSC (btw. how do you send MSC in the first place as you can switch it off in setup, just wondering). Now the only way (I found) for not sending MIDI is to set the send-ID to 6, so the other software ignores the MIDI signals I‘m sending over. I know, this way is not very elegant, but was the only solution we found so far. 

I‘m open for new ideas if there are some!
