How do you make a pianomo roll?

To make a piano roll, you'll need a roll of paper, a piano or musical composition to transcribe, and a specialized punch machine. First, compose or select the music you want to convert into a roll, then use the punch machine to create holes in the paper that correspond to the notes played on the piano. Each hole represents a note, with its position indicating timing and duration. Finally, roll the punched paper onto a spool for use in a player piano.
