I have Superior Drummer 3 and with that I have Loudstakk Metal Drum Grooves, and all the Ugritone Midi Grooves along with a few Toontrack Midi groove packs. These Midi grooves all work with Superior as far as mapping goes. So I got Mixwaves Sleep Token II Drum Library, and None of these groove packs work, even after I change the mapping to Superior inside the program, and Loudstakk has specific Midi grooves based off the different Librarys that exists, Drumforge, Toontrack, addictive ect ect. But No matter what changing every mapping to the correct one within Sleep Token library its not playing the right notes. Has anyone any idea what is happening or what I could be missing.

 

https://www.midiremap.com. that site has an online convertor you could try, and they have a plugin version. No Windows version on sister site, but there is one for Mac. The "free" online convertor will only let you do 3 conversions in 90 days, which is a joke. But you can at least see how it would work.

Sometimes you can just transpose the midi data in your DAW, but if the drums are all over the map it will not fix your problem.
