can you believe i cannot play the piano, i play by ear. Still need to know the root note though. Such a struggle for me cause im very unstructured in beat making...See that's the difference with today vs. old school! I never check to see what key it's in I just go by ear. Sometimes it matches, sometimes it doesn't. I understand if you want to get the key, that makes it easier but I prefer to go by ear. I know with Studio One it has a feature where it analyzes the samples and tells you. I don't know about FL. It probably does.
