Did a Google search but couldn't find one, so I'm asking before I make my own. Thanks.

I have SONAR drum maps for SSD 3 and SSD 3.5 that came with the Groove Monkey Blues Drums set. I don't know if they would be of any use to you, or not. What's SSD up to now? v4?

Thank you for the offer! It reminded me that I have the Groove Monkey Metal Pack, so I tracked down my original download and it has the 3 and 3.5 maps. Unfortunately, things changed in 4 and those are for Kontakt. I was able to get the 3.5 map working, but it's missing some slots from SSD4. Time to do some research on building my own maps.

I also want to build maps for my custom Battery kits, and this video is a great resource. It'll save me hours of looking up midi note names in relation to drums. If you're on here, Scott, thank you.

If you need to make several drum maps, the ins2map utility may make the process faster because ins files can be created using a text editor. The ins2map utility is found in the user utilities thread http://forum.cakewalk.com/FindPost/3392713

Awesome!
