As put in the email from A.C. (post 70 in the thread) Lebia sent cello music. Admitedly there's no reason it has to be all cello... ANYway, it also has the sheet music in there (for a given value of 'sheet' given it'll be holographically projected). So when time comes for the jam session, the V.I. will probably pop up an example. Or Yayoi will get suspicious when she hears where it came from.
(Sudden thought: Holo-Pen-Pen, in a tux, doing the Bugs Bunny conductor routine (Edit: From Long-Haired Hare) to the Jam members)
And there should be enough memory left for Shinji to upload...pretty much anything he wants within reason.
Of course, now that the V.I. "Pen to the Penth" has heard this is may go out and find music Shinji likes (or call 'home' i.e. Prometheus Forge for help).
