Korg Forums

Hello All,
I am encountering a new issue. I am not sure if it is related to the sustain pedal or not but, when I turn on the keyboard and it is fully up, then some keys do not work for a bout 5 minutes then all keys work. Once I unplugged the sustain jack and it started working. Have you experienced the same issue? Do you know of any remedy?
Thanks
Shawn

So tell me,

Power off keyboard > unplugg the sustain pedal > power on keyboard..
Will this problem not occur?

I have the sustain pedal from korg and EXP all time connected and have not occured this problem yet.
