This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

IF MUSIC BE THE INPUT OF COMPUTERS, TYPE ON

Students at the Royal Academy of Music in London can now come to orchestral
composition classes with floppy discs instead of manuscript paper, then hear
their homework brought to life by an electronic orchestra. The discs are
read by a computer, itself linked to a synthesiser that reproduces the
sounds of all the instruments. Any changes suggested during the class can be
entered straight away, and played on the synthesiser. The completed score
can then be printed out on normal music paper.

"For the first time ever, students can hear a full orchestra playing what
they have written," says Paul Patterson, head of the composition department
at the academy. "At the click of a mouse button we can rejig the score to
add timpani, or change the way the brass or woodwind parts of written, and
immediately hear how it sounds. It's fantastic."

The academy is using a computer program called Sibelius, which runs on an
Acorn RISC personal computer. It was written over a period of six years by
the brothers Ben and Jonathan Finn, who live in Cambridge. Complete systems
are on sale for under �2,000. The academy has installed Sibelius
workstations in its studios so that students can compose onto disc without
needing to buy their own system.

There are two ways for the composer to enter music into the work station. To
write notes onto a conventional music stave on the screen. the composer
positions a cursor with a mouse and then uses the keyboard to register the
note's duration. Alternatively, the composer can play music into the PC from
a keyboard connected via a MIDI port, the standard digital music interface.

A number of MIDI programs already let composers print music, but are slow to
cope with changes. "You have to go through a long sequence of keystrokes
before you see anything appear on screen," says Patterson. "It can take
twenty minutes to redraw the screens for a full score."

The secret of Sibelius is that it works like a modern wordprocessing
program. It processes and formats all the information as it is entered,
updating the full score 10 times a second. New notes appear on screen as
they are written or played, and are immediately available for
printing��
