Many Thanks for the information guys
Unfortunately I may not have explained myself correctly

What i am trying to do is trigger the DRUM ROLLS of The AUDYA by assigning one of the switches on the top of the PK5 to do so? Maybe switch 5 0r 6==so that when i tap it I get a drum roll to the pattern I am playing with the 13 note pedals of the PK5. I am a guitar player who stands up and uses the PK 5 to trigger Registrations or Styles.

If I was using a Ketron K 8 midi pedalboard I would require an additional FS6 footswitch for the drum rolls
But i was hoping top be able to use the PK5 to do both tasks --trigger the bass notes and tap a switch for the rolls?

Thanks again
Rusty
