Thank you Donya ...
I tried SynthFont ... it seems to work to some extent. The instruments go a
little haywire though.

Kashyap

Euterpea has a function called "test" that writes a Music value to a MIDI file
called "test.mid" in the working directory. However, to do this, Euterpea uses
Codec.Midi from the HCodecs library to first create a Midi value and then write
a .mid file. Unfortunately, Codec.Midi seems to have some bugs in the .mid file
conversion, and, as a result, the .mid files are readable by some programs but
not others. If you are on Windows, SynthFont (free) is usually able to open the
files without problems.
