I am using an M-Audio M-Track as an audio and MIDI interface, but it really shouldn't matter what hardware interface you are using.

Here is How I am using MG2.

1 - Make sure the IAC (inter-application communication) MIDI driver is active on your system, scroll to the bottom of this page for more info :

2 - Then launch the standalone MG2 app, and make sure that your IAC port is selected as the MIDI output.
3 - Finally launch BIAB and set the MIDI input to be the same IAC port that you set MG2's output to be.

Your system should remember those settings, so you should only have to set it up once.

Hopefully this helps.
