HI. It's not the sample that is the trouble. It's Dim Pro or a setting I am missing in Dim Pro. I chose Sonor Hilite 2 U87-001.sfz as an example. It has a decay of maybe 2-3 seconds, especially in the lower registers.
If I play it in Sforzando, with the Sustain pedal on, the drum plays its entire sample, even if the note event is very very short, just enough to trigger the note. So it can be arranged somehow.
In Dim Pro, the drum sounds only as long as the note event keeps it going. So unless I use note events long enough to cover the full length of the drum's decay (and changes with the note#) I get the decay chopped off. Activating the sustain or using the EG do not seem to help, unless I am doing something wrong.
Even in a drum roll of fast hits, unless you overlap the notes, which sucks up polyphony and is messy to work with, you get a staccato series of rattles, not a series of rapid drum hits with the sample staying alive until the next fast hit.
