Thanks for the great article. I’m using the option 4 at the moment. It all works great apart from one thing. Sometimes, very randomly, when I navigate back on my patch list, MS stops sending MIDI to IAC driver. The problem goes away if I temporarily change the output midi channel to something else and back. I see the midi being received by Mainstage but it is never sent from Mainstage to Kontank after the patch change. This happens only, like every tenth time and only when I navigate back. Would you have any ideas how to get around this problem?
