Interesting... The vibrato on the sweet tenor in my PSR-550 isn't light. It actually seems like it is being used with a modulation wheel, and I think to acutally use the sweet tenor sound on my 550 with a modulation wheel would make the vibrato too heavy.. I wonder if Yamaha compensated for the lack of a modulation wheel and added more vibrato to the sound because of this.. Hmmmmmm
