Sample Programs from NeXSTEP 3.3

This directory contains two example programs to read and write data
between the MIDI driver and standard Level 0 midifile.  The Midifile
format is specified by the MIDI Manufacturer's Association, and is a
machine independant format allowing the interchange of MIDI (Musical
Instrument Digital Interface) sequence data.

The program playmidifile reads a standard Level 0 midifile and plays
it out through the MIDI driver.  This program illustrates both how to
parse a midifile and how to use the MIDI driver in a simple
application.  The playback may optionally be synchronized to incoming
MIDI time code.
 
The program recordmidifile read MIDI data from the MIDI driver and
writes directly to a file in the standard Level 0 midifile format.
This simple commandline utility records MIDI data until control-c is
typed, which then causes the collected data to be written to a file.
The times may be derived from the system clock or from incoming MIDI
time code.

For both utilities, the user must supply a file name argument, and can
give an argument to specify which serial port to accept data on.  He
can also specify a serial port to accept MIDI time code from.

There are a couple of test midifiles supplied to serve as simple
examples; they of course require a MIDI synthesizer to play them on.
See the MIDI driver documentation for further information about the
MIDI driver and about MIDI interfaces that works with the NeXT serial
ports.
