Delete Take or Comp    ⌥⇧⌫

Deletes the most current take or ‘comp’. I don’t do any? studio recording with multiple takes in a row (other than whole songs or phrases) and am not at all fluent in ‘comping’ tracks.

My early learning was strictly live performance of music. I listened to a lot of radio. If I went to a show featuring a band I had heard I was almost invariably disappointed that the band sounded not at all good compared to their records. I had no idea that they could/would stitch together pieces of the music to make the record. Silly me.
