Hi, Ray!

I don't have a clue about any special electrical specs of the
Yamaha, but I can't imagine anything that would cause it not
to work just fine with the HP card.  You could see how different
HP48 programs sound on the Yamaha :) .....
The only difference between HP and Epson cards is the slightly
lower cutoff-and-clamp voltage threshold of the HP cards.  I
don't the Yamaha could possibly care.
