yea that's correct.. I have a bunch of drum kits setup with different samples and hits that i would like to mess around with without creating a new exs instrument,finding the sample, stretching it across the 61 KEYS just to find that i dont want to use that sample anymore.. Then I have to delete that exs instrument out of my library not to create cluster.. Now with that being said Isnt that a fuckin hassle to do to mess around with one sample... I have at least 5-6 samples in every kit.. There has to be a way. If reason and GURU can do it Logic definitely can.. Sounds like your on to something though vpunk
