These objects are a re-implementation of the standard Max MIDI objects using a cross-platform MIDI library (RtMidi). This means that you can use them in Max For Live devices to access the system MIDI ports in an unrestricted way. And.... you can get SysEx!
Only caveat is that on Windows, you have to disable any MIDI input/output port you want to use. If Ableton is trying to use the port at the same time the objects can't connect to it. For this reason, I've added a status outlet to each object to indicate whether the port connection was successful or not. Other than this extra feature, the objects are feature-clones of the originals.
Oh, also the double-click port menu is only implemented on Windows because I genuinely can't work out how to create a pop-up menu on OS X from a cpp project. Anyone have any ideas?
