Hi,
Percussive libraries include hits labeled 1 and 2. I've not been able to understand if these use the same identical samples, and the two different keys are there only for playing rhythms with two fingers; or if they are separate samples, one from the left and the other front the right beater; or they are timbral variations based on different samples.
The answer to this question would be useful when building a percussion map/articulations set for the likes of Dorico or Logic, because if they are identical maybe the map can be made simpler, by avoiding any redundancy.
