josepp,

Regarding Joplin, I have a CD called Scott Joplin: Ragtime Piano Roll. It is a digitisation of the original piano rolls, which were played by Joplin and transcribed to the piano rolls. The sleeve notes state that Joplin was never recorded, so for me, this is like hearing Joplin himself play, and his own personal style of playing comes through. The pieces are not fast.

It is played on a piano, They are not (tinny, computerised-sounding) midi files, but the piano plays the digitised score created from scanning the piano rolls and converting them to midi files (or something like that). This CD combines two of my loves: ragtime and player pianos.

Thanks for the further information on jump music. I can see this addiction is going to get worse, now that I have more artists and songs to find! :-)
