I have a KN6000 with EW-01 card with which I use MIDI bass pedals and an expression pedal. I normally assign the bass pedals to part 15 on channel 15. If I set the expression pedal to total it works fine on all parts including the bass pedals. If I set the expression pedal to part expression it works fine on the parts accessed directly by the KN6000 but not for the bass pedals. I use Program Menus/Sound/Part Setting to set the expression to ON for part 15. Whilst I am actually in the Part 15 setup menu the Expression pedal works as expected and its application to the pedals is toggled by the ON/OFF setting. As soon as I leave the menu the expression pedal no longer has any effect. Can anyone offer a solution to this problem. I have tried many combinations of part/channel setting to no avail. My friend has the same problem with his KN6500.
