With Yamaha keyboards, you have an option of turning on or off the left, right1 and right2 and on some models, touch sensitivity for the style. I cannot remember which ones had the style sensitivity setting, though.
I would think someone that is very knowledgeable with Ketron products would have this information at their fingertips.
Good Luck,
Gary
