PortMedia Files

PortMidi is now maintained at github.com/PortMidi/portmidi. Source 
for portmidi is mirrored here in portmidi/v2.0.2/portmidi.zip as well
as in the SVN repository.

Currently, the other major portion of portmedia is portsmf, a fairly
extensive set of tools for reading and writing standard midi
files. This library also supports a richer representation,
Allegro. This representation is the basis for Note Tracks in Audacity,
and all the cut/copy/paste operations as well as some capabilities
beyond what Audacity currently allows regarding the editing of tempo
tracks and conversion from time-based to beat-based timestamps.

In addition, the library includes a fast implmentation (in C) for a
dynamic-programming-based audio-to-audio and audio-to-midi score
alignment.
