Because of c) you seems to be right OTOH e.g. a natural tom or snare

played two times does sound different to a drum sample played two times,

while the first sample is cut, but if the first sample isn't cut it

sounds relatively natural. Perhaps because of a time difference for the

transient oscillation of the resonance head?
