[cc65] A midi player for the cc65 targets ;)

As you may remember from 2004 I tried to start a discussion about a
simplified abc music library for the cc65 compiler.

During the last few days I have experimented with a package called abcMIDI.
It contains midi2abc and abc2midi. The cool thing is that it also contains a
reformatting package called abc2abc. This allows you to transpose the tune
and change the time base etc.

The sources are all available at sourceforge.net and they are quite modular.
Every tool uses the same parser and the output module is just one c-file
that can easily be changed to create new tools.

So I actually created an output module tocc65.c that outputs the tune as
a c-file that can be compiled by the cc65 and included in a project.

The steps required to play a midi-tune is then:

midi2abc Austin_Powers.midi > austin.abc
abc2c austin.abc > austin.c
compile austin.c and link it to your cc65 application.

The file austin.c will then contain the same number of instruments that
the original midi file had. Depending on your hardware you can then
play just the melody or perhaps the melody and a few other voices.

Ok. This was not a real midi player. But as the internet is swamped
with midi files this is an easy way of playing music on a cc65 target.

Here is what the Austin Powers theme looks like in 4 voices.
No editing by hand. This is what these tools produce.
Playing time is 2 minutes 34 seconds. The original midi file was 21k
and the resulting abc byte array is 3.7k. The original midi file played
on a multitimbral synthesizer sounds better than the abc file on the
Lynx. But the Lynx version is not bad either.
