Garritan JABB cymbals

I’m sorry if this question has already been addressed, but I can’t find it in the forums. I can’t get the ride cymbal to play using the Garritan JABB Drum set (full). The splash and crash cymbals work, but the ride doesn’t play. Any guidance would be greatly appreciated!

I guess the first thing to do would be to check that the Percussion Map includes the ride cymbal, and that it’s on the correct key.
