just got 9000 pro 1 wk ago and LOVE it- so easy to use - BUT other day when i turned it on the voices have some kind of horrible effect sound stuck on them- especially noticable in the "live" sounds- piano, nylon guitar, etc- it almost sounds like a flange effect or something- called yamaha and they were supposed to call back within 24 hrs- but no reply yet- any ideas??? i really wanted to cry when i first heard it- i waited and researched for this keyboard and was so exited when i got it. any help??
thanks-
take care,
shara
