It would be great if it were possible to re-purpose the two switch jacks on the rear of the KPA to send instead of receive signals. At present, I don't use those two switches at all. If they could be made to switch between receiving switch information and sending switch information, then they would become much more useful for me.
For example, imagine being able to use those jacks to send channel change messages to another amp. This could be programmed into a performance maybe. Or, one of the jacks could be used to send switch messages to the aux in of my H9 pedal. Now instead of using a separate switch pedal to change settings on my H9, I could just program the message into a performance, and have the KPA do it.
I realize that this is a hardware change, which may not be possible with the two switches on the KPA, but I just thought I'd put it out there, just in case.
