Hi, So I'm mapping up some hihat samples. I want the closed hat to mute the open hat (easy, assign both to a group, voice count to 1). However, I want to be able to play the open hat polyphonically as it sounds much better. There was a documented 'trick' from here a while ago that made this possible, and I'm trying to set this up but the behaviour of the EXS24 is strange. The trick is this: add a new zone to play another sample on the same key as the closed hat. The volume of this sample will ultimately be zero but for now we'd like to hear it. So every time you play a closed hat, two samples/voices are playing. Increase the number of voices on the group to two. Now when you play the open hat, it's two note polyphonic, but when you play the closed hat, as it plays two voices it should cut off any already sounding voices. You can increase the number of voices to 3,4 etc as long as you add extra null samples to the closed hat sound. Now this is all well and good, and seems to work for loads of people, but not here. With the 2 voice example, if I hit the open hat and leave it to ring, then hit the closed hat, instead of the open hat stopping and the two closed hat samples playing instead, only one of the closed hat sounds (the lowest zone) and the other sample clicks. The open hat keeps sounding until it decays. The EXS24 is not reassigning voices that are currently sounding in order to play new notes. Is there something I'm missing to get this working? This is Mac Logic 7.0. This behaviour is the same in Mac Logic Pro 6.4.2 and also exactly the same in PC Logic 5.5.1 SO it *must* be something I'm doing wrong, although I haven't a clue what...? Many thanks for reading and help would be appreciated.
