I'm trying to send midi clock from mainstage to an ipad via bluetooth midi (to the app ApeMatrix) but having an issue where every time I create a new external instrument channel strip and and select "start sending midi clock" in the Midi Output tab, it crashes all my midi devices. Meaning I can no longer get an midi data into OS X at all from any of my controllers. Restarting the computer fixes the connection.
Any idea? Thanks!. Using Mainstage 3.4.4
