Yamaha PSR-630: Need fix for reversed polarity of sustain pedal
My name's Jane and I have a PSR-630, and when I use my sustain pedal with it the function is reversed (it sustains when it's in a resting state, and it releases the sustainment when it is depressed). I was wondering if there's a way to reverse the polarity on the sustain pedal input of the keyboard without opening it up and switching wires and stuff. My friend has a Roland, and he can do it just by pushing buttons and changing it on the display.
I was checking the manual of the PSR-630 but I haven't been able to find anything about it in there.
