I have a strange problem. I'm using a MOTU microlite 5 channel MIDI interface, LogicX 10.2.2 on MacPro 10.10.5. Logic seems not to be able to send MIDI properly to Port 2 of the interface. I can send existing MIDI tracks to all the others successfully. The panel indicators of the interface show MIDI out for all but the second port. However Logic will send MIDI sync to this port (when turned on) as indicated on the interface. There appears to be an object in the environment attached to this port. The interface works totally normally in Pro Tools, port 2 works as it should. When I create a new track in Logic, the port is not available as an option, however it is available in the track parameters of existing tracks. I've updated MOTU drivers, reset all except key commands, tried opening new empty project, checked MIDI setup, restarting. No luck. It seems that somewhere in Logic it has blocked the availability of this port for key information. It recognises it for sync output. Any suggestions?
