Remote Switching a PC Device via Mastermind

[edwinstar]

Hello! My Mastermind controls Lehle Switchers that only accept Midi PC, no CC, for changing their switch state.
Now Sometimes, in addition to the Mastermind, i want my DAW (Ableton Live) to also perform those switching actions. The DAW is connected to Mastermind via USB.
My question: What do i send from Ableton, to switch the IA Switch that Switches the Lehle?
Since the Lehle only responds to PC, but remote switching IAs is done with CCs, do i need to setup dummy CCs? Or is there a more elegant and simple way?
Thank you!

You could turn on MIDI Merge for the USB port. This will cause the GT to forward any MIDI messages coming in from Ableton to the device(s) connected to the Mastermind's MIDI output.

Thanks! I found a good instruction how to make CC Link work. It‘s working fine!
