Received a telephone call (between gigs) earlier in the day from Larry reporting his latest S900 problem. Truly disappointing news especially after the problem with his first S900. In addition to reporting this to Sweetwater Music (place you purchased the 2nd S900 from),

Larry, I recommend contacting Yamaha USA and asking to speak to Steve Deming, head of Customer Support, about all the problems you're had:

Telephone: (714) 522-9011
Email: ycasupport@yamaha.com
