Haha. If Hasbro went to Pixel, I'm sure he'd be very confused.
Also, make sure to lower the MIDI volume along with the SFX, listening to them on their own, they're very loud too.
MIDI is out of my control for the moment. There is no MCI command that can adjust volume of a MIDI. If SW Synth is adjustable (which I know about it in the Windows XP volume mixer), it was the only way.
Anyway, I don't have anyone to play with, but I'll hack a look.
