Agree with Jeff on this.
I've got a couple of articles on using the MTRX and using MOM with it too.
It isn't a walk through in terms of how to set it up but it does cover the way I use it for music.
The great thing with the MTRX is how freely you can configure it.
I do autosave mine, because I am frequently changing input source assignments going directly to the monitors.
I keep a backup of a "known good" configuration though.
