Uncle Dave,
This will make you happy! The call just came letting me know if you can sustain the right hand without sustaining the left hand sound. When you get your new PSR2000, just hit the function key and you will have the ability to select what individual features you want to Left, Right, Layer, etc. which includes the ability to check a box for sustain on and off. This should make you happy! Unfortunately, you have to wait a few months to get your hands on one of these new boards.
