Overview:

	Mixer4 will look for 3 text files when it is run:  The tracks.txt file
 assigns wave files to channels in the mixer.  The faders.txt file contains
 settings for all your volume, pan, and effect parameters.  The prefs.txt file
 contains a few user preferences and allows you to switch between mixing the
 entire song or just mixing a section.

	The general idea is that you start a line of text with a command like 
"v" for volume followed by several tab separated values pertaining to that 
command.  The first parameter is almost always channel number.  So, you enter 
a command, then a channel to apply that command to, and then other parameters 
such as threshold and attack time for a compressor.  

	It was an intentional design that 0 dB full scale is the volume limit 
throughout the mixer.  So, mixer channels should never show peaks above 0 dB.   
This lack of headroom may appear to be a limitation compared to other mixers, 
but realize that in return you gain "footroom."   Whereas in other mixers as 
you lower a fader you will get rounding errors, in this program you will not.  
In other mixers, if you exceed 0 dB on a channel you would have to lower the 
master fader to compensate, resulting in yet another calculation and source of 
error.
