Q: MIDI Network challenge

I am syncing together two MacBook Pros using an Ethernet link - to be precise an Ethernet to Thunderbolt bridge to Thunderbolt since one of the laptops doens't have Ethernet. I have set this up using the Network setup in Audio MIDI Setup's MIDI Studio. One machine, running Ableton Live, acts as the master and the other, running Resolume Avenue 4 video application, is the Slave. When I play my tracks in Ableton they trigger different video clips in Resolume. So far so good.

The challenge is that creating this MIDI network seems to have thrown out the rest of my MIDI connections on the Ableton machine. I want to use a small MIDI keyboard to play samples live and I also want to send MIDI patch changes to fx units and lastly work with a Keith McMillen SoftStep 2 to trigger scene changes on Ableton. But this MIDI network running Resolume seems to have ditched these other MIDI connections.

Have I done this the best way? How can I keep direct MIDI control of aspects of my Ableton setup and still trigger clips in Resolume on a second machine? I am using MIDI note changes in Ableton to do the latter.

Thank you
