That "Blue Crap" is not for anti-tamper protection. It is a conformal coating to prevent "Tin Whiskers", galvanic corrosion, and solder joint failure. If they wanted to deter tampering, they'd encapsulate it. There isn't a lot of super-seekrit technology in the VSP!
Outside of the US market, the cancel button is allowed, so it stands to reason that the pin/function will be present.
One of these days when I have nothing better to do, I may reverse-engineer it and figure out how to make new noises. The Yamaha synth chip is very flexible!
Looks like they upgraded it for 2013 from the
YMF807 to the
YMF827.
