The problem exists on all uses of the plugin, it can be seen on test page: http://jazz-soft.net/demo/MidiInput.htmlSetup:
I'm using the built-in internal IAC Bus Driver to send MIDI out notes from Ableton back to the input of the mac.
(Other MIDI software sees the correct signals. I am currently using MidiBus for Processing and it is retrieving data correctly )
Here's an illustration of the problem. The F and G notes are recognized perfectly, but not the A + B if triggered simultaneously.
