Hiya... I have owned the YPG-625 and 635 and know what to expect with sustain. I have gone thru the DGX functions and can not figure out how to increase the sustain when the pedal is depressed. The pedal is fine. I tried 3 different ones on the DGX and the YPG. I can increase the sustain for when the pedal is NOT depressed but the pedal sustain is lame, way too short. Any help is much appreciated. Thanks. Larry ♫
