I've just discovered another problem with my Tyros besides for the USB issue. I plug in my Shure SM58 and I get a big hiss (similar to a ground hum). My voice can still be heard above the noise, but the noise is completely intolerable.
I found the eq setting to be +10 (which I didn't set - is that default?) on the high, but turning it down only improved the problem marginally. Obviously vocal harmony won't work with such a noise.
Anybody experienced similar problem?
Assuming it really is a problem, Yamaha will sort it out together with the USB problem.
