Several midi connection trhu ethernet

Hello,
Today I try to create redunduncy with my 2 mac (10.14) to control Qlab with the SQ5.
The Apple RTPmidi is not working well beacause my second mac is too old, so I try with MIDI Control but I cannot connect my 2 mac at the same time, did I miss something ?

Thanks

The SQ will only take 1 midi connection @ the time.

You can have a look @ the BomeBox to create a redundant link

(Sq will connect to BomeBox and the mac’s will connect thru the Bome network to the Bome Box, Both of them can talk to the SQ).
