Hello,\n\nI am having trouble with my Kurzweil pc88. When the sustain pedal is plugged in (pedal 1 jack), nothing happens. No sustaining at all. If I unplug it and have no pedal plugged in at all, then the keyboard completely sustains everything all the time. If you plug the pedal back in without cycling the power, it goes back off. I have tried a hard reset with no success.\n\nI am guessing this must be a problem with the keyboard itself as the pedal works on another keyboard. \n\nAny suggestions or ideas about this? \n\nThanks in advance!
