Re: fcb1010 setup
I had similar problems programming my FCB. I emailed Behringer support and they sent 3-4 .pdf files with tips on recalibration and how to configure the unit. I don't have the files now, but it maybe worth contacting Behringer to see if they can send them to you.
Also, as Aleclee said, it's very much a two-way process midi programming. You need to know what to send out of the FCB for it to 'talk' to the G major. Your G Major manual should have a midi implementation list in it which will have a control no. against a certain function. Ultimately, depending on how you are going to use the FCB, you assign the FCB a control no. to one of it's footswitches (and a value for some parameters) and that implements the action in the G Major.
I know that hasn't helped much, but once you get your head round it, it does become easier...I think.
