Drum map transposition

Is there a quick way of editing drum maps for situations such as where one device thinks midi note C0 is octave -1, and the other thinks it is octave -2? Some drag and drop functionality would sure be nice here. (Why doesn’t drum mapping have the C3/4/5 switch that expression mapping has?)

Also, the VST has two notes for the same sound, alternate striking I guess. (It is the Kontakt SS Tamtam in this case.) Are these just irrelevant for notation purposes? Just wondering if there is any point mapping them.

No, at present there’s no good way to shift all of your mappings up or down by one or more octaves, but I agree that would be a good feature to add. I’ve made a note of it.
