       | file (.mid) downloaded. Came up in Garage Band and sounded nice.

       | If you find a duplicate it often isn't. They often cut a bunch of
       | rolls and then threw the master. If the roll proved popular they
       | made a new master which would be slightly difierent but have the
       | same catalog number. Tracing these 'editions' is often part of
       | the fun.

       | 
       | Some software I wrote for piano roll analysis and transcription:
       | 
       | - Unroll: https://zulko.github.io/unroll-online/ - upload a piano
       | roll midi file and have it quantized and converted to lilypond
       | sheet music. More about the process in this blog:
       | https://zulko.github.io/blog/2014/02/12/transcribing-piano-r...
       | 
       | - Pianola: https://zulko.github.io/pianola/ - upload a piano roll
       | midi file, and it plays with the piano roll and keyboard
       | animation (you can zoom on some parts, slow down etc).
       | 
       | Some transcriptions made with these tools:
       | 
       | - Hindustan: https://github.com/Zulko/sheet-music--hindustan
       | 
       | - Gershwin - Sweet and Lowdown: https://github.com/Zulko/sheet-

           | When I was about 10 I picked my first ever CD at a music
           | shop, and it was a recording of the Gershwin piano rolls,
           | because the cover photo caught my eye [1]. I didn't really
           | understand what I was listening to, I assumed "piano roll"
           | was a musical genre, like "rock'n'roll", until years later
           | when my English became good enough to read the CD's booklet.
           | 
           | It was also a time when all these midi files started being
           | available, like the 6000 rolls from Terry Smythe [2], and I
           | figured out transcribing these could be a good way to learn
           | old-school Jazz, which is otherwise difficult to find as
           | sheet music.

               | In terms of the music being played, piano rolls can be
               | different from "normal piano music" because it's not
               | played live by a real human, so it can have complex parts
               | with full chords, additional voices, all with perfect
               | rhythm and no wrong notes. This can be very compelling
               | when well executed on the right songs (and it can also
               | sound "mechanical" on others).
               | 
               | There isn't a huge market for piano roll recordings, and
               | these recordings are rare. It's a niche topic that can
               | attract
               | 
               | - Older people who have known the time piano rolls (say,
               | until the 1950s)
               | 
               | - People nostagic of old times in general (in particular
               | the 1910s-1940s), the age of early jazz with stride piano
               | and early Broadway.
               | 
               | - Music scholars, because some of these rolls are of
               | historical/musical importance, in particular those
               | "recorded" by George Gershwin or Fats Waller and other
               | big names. A lot of material exists only as piano rolls.
               | 
               | For the example of the Gershwin CD I posted above, it was
               | produced by musicologist Artis Wodehouse [1] in
               | parnership with the yamaha disklavier pianos iirc [2], so
               | my guess is this was a passion project above all, with a
               | bit of Yamaha marketing.

         | I've seen pianola rolls and even played one as a child. But I
         | have wondered as an adult what the 'listening quality' of the
         | music is / would be. What got you into them and could you share

       | An interesting prospective project for a technically minded
       | musician would be would be to find an automated way to "correct"
       | the surviving corpus of Welte-Mignon[1] recordings. They were
       | designed to capture the small nuances of performances (such as
       | dynamics), and a large number of historically important musicians
       | made recorded performances in this medium before the era of sound
       | recording. In my strongly-held opinion, the rolls were marked in
       | an uneven and imprecise way, making direct playback on anything
       | but the original recording apparatus inaccurate. A common trait
       | of modern renderings of these rolls as sound recordings (as found
       | on CD or on Youtube) is an unevenness of tempo and a seeming lack
       | of synchronization of voices (really piano keys). However, the
       | mechanical quirks and imprecision in the recording apparatus must
       | be regular enough to allow for a more accurate version of the
       | performances to be reconstructed, without relying on unduly many
       | aesthetic assumptions.

         | 
         | How did the Welte-Mignon actually work? It seems almost
         | miraculous that the dynamics can be captured on a piano roll
         | and replayed successfully. Not perfectly, as you say, but
         | pretty damn close.
