Hi Tom,
It the usb thing and something keeps happening to the hard drive (it's a Yamaha drive for Tyros). The HD often goes into some sort of seek mode and locks up the system - have to reboot. re: usb, it's the same problem so many have had I suppose.
There is a dealer here that I have bought from and had repaired my instruments for many years (about 25). He was here at the house last summer and I had him take a look at it then. He told me he would not go into it. Basically, it is throw away stuff or nothing repairable inside if I understood him correctly.
Did you get my message re your midi problem ?
Danny
