moxf6 has a mind of it's own

[Dave Nixon]

I have had my Yamaha MOX for several years with no issues and now it suddenly steps down the pitch after I play it for a bit. I have tried a reset to no avail. I never use the pitch wheel, could it be malfunctioning and how do I disable it to test? Any other suggestions would be helpful.

You should be able to set the Pitch Bend Range to 0 semitones, which should stop the Pitch Bend Wheel from having any effect on the sound. That might help you determine whether there's something about the wheel-- either physical or electronic-- that's causing the drop in tone.
