Mysterious M port Date: Apr 2, 2009 10:26:47 AM PDT Author: ProRemote Welcome to the forum! The M port that you may see on the newer version of the ProRemote MIDI driver (in Audio MIDI Setup.app) is the dedicated MIDI port. This port is used by Pro XY to send and receive MIDI. Make sure you select this port for use with Pro XY. The first 4 ports, Port 1-4 are for control surface use with apps like ProTransport and ProRemote and are not needed for Pro XY. If you use ProRemote's XY Pad feature you will also need to select the M port. Last modified by ProRemote on Apr 2 2009 10:27AM   Reply to this Post
