Hey, Paul. This is a super-dangerous board run by a long-time G.A.S. sufferer.
Synth guitar is a lot of fun, but you're right, you really need to hear a good setup. There's a Roland VG-8 mailing list that talks a lot about this stuff at:

I don't have any of my music up yet, unfortunately. I'll try to put something up in the next month or so.
Cheers!
