Hi Mike,  I've 'converted' a number of MIDI files to WAV files using
GoldWave and CakeWalk.  Actually, it's not really a conversion but
rather a recording.

First I open Cakewalk and load up the MIDI file.  Then I open Goldwave
and select "New File".  This allows me to select the bit rate and
sampling rate for the end result as well as the approximate length of
the file (the result can be 'trimmed' later).  Next I start the recorder
in GoldWave and then start playing the MIDI file.  If you're using
SoundBlaster, you might want to check your mixer settings before
starting to insure that the tone controls are set to zero dB.

What I've found most desirable about this method is that if you have
two or more tracks in the MIDI file and the PAN settings are somewhere
other than 64 (center), you end up with a nice stereo recording in the
WAV format.  (I am also working on creating a CD of original music.)
And what I also like very much about GoldWave is the flexibility it
offers to modify the file in numerous ways, i.e., tone, speed, noise,
etc.

Then, when I'm all done, I usually convert the file to the mp3 format
and store it in a special location for archiving, since the mp3 files
are much smaller than the WAV files.

There are also a number of WAV to MIDI programs around these days,
but I still haven't found one that's really easy to use and that gives
accurate results.  The progress that is being made reminds me of the
way things were when mp3 first came on the scene some years back,
when it was only available in DOS... Anybody remember DOS?  ;-)
Just kidding!

Musically,
