Two sounds to one note
It would be nice if, when editing the drum set, I could relate two different sounds to one single note. For example, if I'm creating a brazilian tambourine, I would like
the note on the first line to have the sound of the low tom together with the sound of the closed hi-hat,
and the note on the second line to have the sound of the high tom together with the sound of the closed hi-hat
because every sound in the brazilian tambourine is some sound of the skin together with the sound of the metal jingles.
