Tempo Mode and Map:
-------------------

	If you wish, you may work in tempo mode.  This allows all your time 
entry information to take the form of measures, beats and ticks (480 ticks per 
beat) instead of minutes, seconds and milliseconds.  You may change meter and 
tempo throughout the song and such changes are specified by adding the "tmap" 
command to the faders.txt file.  First, add the word "tempo" to a line of the 
prefs.txt file to activate this mode.

	If using tempo mode, at least one tempo, beats per measure and number 
of measures must be entered for the song.  Begin a line in the faders.txt file 
with "tmap", then tab, then tempo in beats per minute, then tab, then beats per 
measure, then tab, then number of measures with this tempo.  For example,

tmap	114.1	3	48

means set the tempo to 114.1 bpm, and the beats per measure to 3 for the 
duration of 48 measures.

Let's say at measure 49 the tempo changes to 122:

tmap	122	3	16

	So again, "16" refers to the size of this new section.  The start of 
the section is always directly after the previous section ends and is done 
automatically.  I think this method of mapping is far less error prone than the 
user, myself included, trying to calculate at which measure a new tempo begins.

Please note! In tempo mode the first time entry in your mix should be

t	1	1	0

which means bar 1, beat 1, tick 0.  This is in contrast to regular time mode 
which starts with 

t	0	0	0

for 0 minutes, 0 seconds, and 0 milliseconds.

	It is possible to use negative beat or tick values in a time entry! 
But, the measure number alone defines what section of the tempo map you are 
using.  Therefore, using a negative beat or tick value in the first measure of 
a new section may have unexpected timing results.  Otherwise, negative values 
can be useful.  

t	3	2	-240

is a time entry for measure 3, and 240 ticks before beat 2.

	Remember that you are entering tempo in beats per minute, so that if 
you change what is defined as a beat, from a quarter note to an eight note, for
example, then you should enter a tempo that is doubled.  
In other words, a measure of 8/8 time at 120 bpm is equal in duration (in 
clock-on the-wall time) to a measure of 4/4 time at 60 bpm.
