A collection of utilities for use with a midi device, including a app called Adagio that "...will play a pre existing score, record midi events performed live, or do both at once."
CMT includes:

• Adagio: a simple text-based music language, and software for recording, playing, and converting text to/from standard MIDI files.
• A real-time programming environment, based on C, that is ideal for writing interactive music programs.
• Applications: Conduct, EXget, EXput, Midi Monitor, and many programming examples.

CMT has three major attractions: the flexibility of an open ended design, the availability of source code, and low system cost.
