If anyone out there is interested in the "how to" for "Sold Me Down the River" - I think I have it figured out. Here's a sample I recorded with midi drums, two guitars and bass.

Sorry only getting a few bars of the opening drum.

Try it again - should work. If not, send me a note and I'll email you the file.
