[ Rob DeLand asked if commercial music rolls are available in the UK. ]

"Commercial" meaning you can buy them, yes, but commercial-quantity, no.

Malcolm Robinson (Southport Rolls via Frances Broadway) uses a scanner
to make Duo-Art recuts, and Steve Cox (Laguna Rolls) has a very accurate
photo-cell reader which writes a DOS file which is then processed to
simulate a MIDI file for inputting to SeqWin where it can be edited.
Duo-Art codes appear on the screen as very short high treble and low bass
notes !

Steve's Duo-Art recuts are highly regarded by the most exacting of
critics here, but his new MIDI file to Duo-Art transfers, while they
produce about the right general strength of playing, have a strangely
uncommitted character - though this might be the quality of the original
performance, of course. (Addresses were in MMD 960801.)

Rex Lawson is pursuing what most theorists seem to regard as a hunt for
the Holy Grail, punch-for-punch copying.  He has done a few manual
transfers using a magnifying glass (notably from Red Welte rolls via a
continuous-process photocopier) but has now found a suitable scanner
which he is trying to teach Apple IIe language. (Apple IIe's are given
away by schools - that's why.)
