Instead of the old sound module or keyboard, you could instead use a

You aren't kidding about that too much stuff comment. I've had a setup that worked perfectly at home and wouldn't at a gig, because every element in the chain had to be turned on in exactly the right order (PC, keyboard, interface, piano emulation software) or it couldn't sense the other pieces. Once it took more than an hour of trial and error to get a sound.
