I guess I wasn’t as clear as I needed to be in my original post; try again:
What I’m trying to do is run Ardour 3 on a Linux host. No other instance of Ardour is running. In Ardour, midi goes to a midi track to be recorded and is also sent over the network to an OSX machine.
On the OSX machine, a stand alone instance of VSL receives midi, processes audio and sends it back to Linux/Ardour to be recorded.
That, I guess is the simple case; of course edited midi could be subsequently sent again to OSX… and so on.
I’m using jackd -dalsa, qmidictl, a2jmidid and jack_netsource on the Linux side, and jackd -dnetone and ipMidi on OSX.
Again, this works for a short period of time, but then the connections are lost, and everything must be restarted to continue.
Sorry for the long explanation; I hope that’s enough to be clear.
Appreciate any help!
