Fork

This is my (Benjamin Summers) fork of Div's MIDI Utillities.

Quick Start

Run everything

To do a quick build+test of everything do this:

| $ ./test notes | ^C | $ ./test timing | ^C

Then do 'cat test' to see what's going on.

Code Layout

All files have a header explaining what they are for. All of the *.c files currently correspond to an executable or a library.

Goals/Changes

I want to make more programs like this, and I want them to be easier to chain together in the shell. My goals for the existing programs are:

• Remove Windows support; Nobody uses windows anyways. :)
• Use stdin/stdout instead of fifos for midi data. I want to create pipelines with these programs. Use fifos or socketfiles for non-midi input.
• Make the code more readable (to me).
• Understand all the code.
• Add many more utilities including:
  • A program that takes an smf file and produces a realtime stream on stdout. | midiplay foo.mid > /dev/midi
  • A program that combines multiple inputs syncronusly. | mjoin <(tee in.smf </dev/midi1) <(midiplay b.mid) >/dev/midi1
  • A command language for changing smf (e.g. ed).
  • A streaming version of it (e.g. sed).
  • A looping player that picks up smf file changes as they happen.
  • A visual editor on top of the command language (e.g. vi).
  • pipe-able wrappers around jack/fluidsynth/etc.

Building and Dependencies

You'll need a POSIX operating system with OSS. To build you'll also need the plan9 utillity "mk", since we use that instead of of the POSIX 'make' It's available as a standalone program and also comes with the 9base and plan9port packages.
