@d-healey Ah, lovely. Thanks, searched the forums but not the docs with the right keywords.

I have a feeling I'm doing something wrong, as it seems that this should be working. Basically:

This is the same sample, assigned to C3 and D3. C3 starts at the head of the sample, D3 starts later. I cannot get a working result, both keys playback the same start position. Whatever key was edited last is what both keys play.

Went into the XML and tried setting "Duplicate" for both keys to 0 and 1, neither works (setting both to 1 results in no sound). Any ideas would be much appreciated.
