Sorry I was unclear...
I am putting together a performance. The gong sound is in a rhythm set, no gong banks, unfortunately. What I was wondering is if I can use that last key to trigger the gong sound from the rhythm set. I've tried everything I can think of, including setting the split on the last key to trigger the right rhythm set (MIDI Ch 10), but the key isn't bound to the gong (I get nice high chimes

)...and I don't believe it can be moved...
Thanks for your response!
