UPDATE:
I ended up using Paul’s EZDrummer Drum Map since it got me closer to the ideal transfer than what I had created, though still not perfect. For now his map will do since I really don’t have time to figure out how to make my SD3 Drum Map work. I still have a few more charts to port into Dorico, plus more drum parts that need to be added to the charts I’ve already transfer.
Apologies to Lindsay for not finishing the SD3 Drum Map. I thought I would be done by now, but alas that wasn’t the case. You may want to use Paul’s map, if you haven’t already. It’s pretty good! Thanks for sharing it Paul!!
