Hey @Monkeyman not quite sure what you mean and I don’t want to speak out of turn (@bradholland or @Mickey please correct me if I am wrong) a sample will load into internal memory if it is 2mb or less. If it’s > 2mb then it streams from the storage (internal or sd). I don’t think there is any way to force one way or the other and it’s just how it works. As someone with no inside knowledge of the internal code it looks like they took the available RAM(64)/number of tracks(32) to get 2mb per track. Unless down the line a change is made that allows dynamic Ram allocation per track then the choice will be use a file < 2mb or stream from as and see a slight delay on the a button in loop slice mode.
See the below post for approximate lengths to use to stay under 2mb.
