Hey there,
I just thought, as i was editing hitpoints for sample replacement on acoustic drums, that it would be such a immense time saver if there was some kind of filtering before the detection algorithm, so that one could, for example, focus the detection on the fundamental of the snare or tom in question.
Maybe even an intelligent detection, which automatically adapts to a given instrument or shell specified by the engineer? I think that that would level up the workflow immensely for many people working with sample replacement 
Also, maybe something like that could make the algorithm which detects the strength of each hit to translate to Midi more accurate, as in my case the hit Velocitys are all over the place quite often.
Cheers!
