sorry guys for the confusion.
i'll go step by step.
i create an instrument with some kick drums form a folder on an external hard drive.
i then go and save this instrument in a new location in my user library. the instrument saves with all of the wav files from the instrument, all copied to the new location as well.
if i decide to edit this new instrument again, and i try to save it, it creates a new instrument file, recopies all the wav files again, adding a -1 to the name of this new instrument.
i would like to just overwrite the old instrument when i save it, not create a new on and avoid the wav files being copied again and again.
hope this is clear...
never mind, it only copies once i was mistaken
