First off, I was a bit imprecise in that comment: this change only affects the Gig format engine so far, not the SF or SFZ engines yet. > This change is good for most drum items, for example when you play a ride > cymbal, but not for a hi hat.

So maybe we can discuss this a bit more. I was recently investigating how to make high quality drumkits sound as natural as possible with the sampler. And fact is, the way it was before the mentioned commit above, that is when voices of an exclusive group were killed even when triggering the same note again, sounded horrible synthetically. Especially on a ride cymbal, when the sampler simply chops off the previous voice while playing a roll on the cymbal, that sounds like somebody is pressing the fast rewind button on a CD player, but definitely not like a natural kit. But since a drumkit has to obey the layout of a typical MIDI drumkit, so it can be played with i.e. any E-Drumkit (using pads), the ride cymbal has to be placed into an exclusive group, right? > Also, think about a hi hat that you open and close gradually when it is > hit, the former hits really needs to be quiet - especially when you > gradually close the HH while playing on it.

Right, the hi hat is probably the most complicated part in a high quality drumkit at all. So far I have just experimented with simple two way open/closed versions of hi hats, but not yet version where you can control the openness gradually. So I still have to experiment with that these days ... Before I commited this change, I discussed it with Andreas, because I was unsure about it as well. And he said, it seems as GigaStudio is solving it like this: it chops off voices of the same note in an exclusive group, however with a longer release time than LinuxSampler (did). So I am wondering if that would be the best trade off for this overall problem. What do you think?
