Tclmidi 4.1

Tclmidi is a language designed for creating and editing standard
MIDI files.  Since tclmidi is a language supporting function calls,
recursion and conditionals, you can use these features for editing,
sequencing and writing complex scripts.  The brave might even want
to try their hand at algorithmic composition.

The basis of tclmidi is John Ousterhout's popular TCL language.
Tclmidi is implemented as a loadable library so you can embed
it in any TCL script along with any other TCL extension you might
find useful.  This include the TK graphics extensions.

WHAT'S NEW IN TCLMIDI-4.0

Quite a lot actually.  The driver code has been ripped out.  This
means you will no longer be able to use tclmidi to play or record
midi files.  It was just getting too difficult to support all
the different OSes as well as the different adapters. 

I've also completely reimplemented the code behind the tclmidi
commands.  Previous releases implemented the TCL extensions in
C++ (and if you've been using tclmidi a very long time, you
might remember a version called tclm that used C).  In the
past year or so I've discovered the wonderful language called
Eiffel.  Tclmidi is now written in Eiffel and based on a MIDI
Eiffel library I wrote called midi-eiffel.  Eiffel is a great
language and I strongly recommend it to every one.  In fact, you'd
probably be better off writing your MIDI applications directly
in Eiffel with help of the midi-eiffel library.  Aside from the
typical problems found with any new major software release, you
should find this new version of tclmidi more robust, fuller featured
and easier to understand.

REQUIREMENTS

You need tcl-8.0 or tcl-8.1.  You also need SmallEiffel.  There
are different Eiffel compilers available and their standard libraries
are not compitible.  I chose SmallEiffel because it is both fast
and free.  Furthermore, you need SmallEiffel version -0.79 not the
latest -0.78 version (they're counting backwards from -1.00).  Tclmidi
tickles a bug in -0.78.  Hopefully this will be fixed soon.

You will also need the midi-eiffel package. 

WHERE TO FIND SMALLEIFFEL

Since tclmidi requires an older version of SmallEiffel at the
time of this writing, I'll also keep SmallEiffel-0.79 available
at ftp.boogie.com.
