</Table>
|
|

<P>
|
|
sets the tempo to 120 beats/minute. You can also use the tempo command
|
|
to increase or decrease the current rate by including a leading “+”,
|
|
“-” or “*” in the rate. For example (assuming the current rate is
|
|
120):
|
|
|
|
<P>
|
|
|
|
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>

will increase the current rate to 130 beats/minute.
|
|
|
|
<P>
|
|
The tempo can be changed series of beats, much like a rit. or accin
|
|
real music. Assuming that a time signature of <SPAN CLASS="textbf">4/4</SPAN>, the current tempo
|
|
is 120, and there are 4 beats in a bar, the command:

</Table>
|
|
|
|
<P>
|
|
will cause 4 tempo entries to be placed in the current bar (in the
|
|
MIDI meta track). The start of the bar will be 115, the 2nd beat will
|
|
be at 110, the 3rd at 105 and the last at 100.
|
|
|
|
<P>
|
|
You can also vary an existing rate using a “+”, “-” or “*” in
|
|
the rate.
|
|
|
|
<P>
|
|
You can vary the tempo over more than one bar. For example:
|

|
|
|
|
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>

</Table>
|
|
|
|
<P>
|
|
tells
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> to increase the tempo by 20 beats per minute and to step
|
|
the increase over the next five and a half bars. Assuming a start
|
|
tempo of 100 and 4 beats/bar, the meta track will have a tempo
|
|
settings of 101, 102, 103 ... 120. This will occur over 22 beats
|
|
(5.5 bars * 4 beats) of music.
|
|
|
|
<P>
|
|
Using the multiplier is handy if you are switching to “double time”:

Note that the “+”, “-” or “*” sign must <SPAN CLASS="textit">not</SPAN> be separated

<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> doesn't really understand time signatures. It just cares about

|
the number of beats in a bar. So, if you have a piece in
|
|
<SPAN CLASS="textbf">4/4</SPAN> time you would use:

|
|

<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>

For <SPAN CLASS="textbf">6/8</SPAN> you'd probably want either “2” or “6”.
|
|
|
|
<P>
|
|
Changing the time also cancels all existing sequences. So, after a
|
|
time directive you'll need to set up your sequences or load a new

groove.<A NAME="tex2html59"

Even though
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> doesn't really use Time Signatures, some MIDI
|
|
programs do recognize and use them. So, here's a command which will
|
|
let you insert a Time Signature in your MIDI output:

<B>TimeSig NN DD </B>
|
|
|
|
</td></tr>
|
|
</Table>
|
|
|
|
<P>
|
|
The NN parameter is the time signature numerator (the number of beats
|
|
per bar). In <SPAN CLASS="textbf">3/4</SPAN> you would set this to “3”.
|
|
|
|
<P>
|
|
The DD parameter is the time signature denominator (the length of the
|
|
note getting a single beat). In <SPAN CLASS="textbf">3/4</SPAN> you would set this to
|
|
“4”.
|
|
|
|
<P>
|
|
The NN value must be an integer in the range of 1 to 126. The DD value
|
|
must be one of 1, 2, 4, 8, 16, 32 or 64.
|
|
|
|
<P>
|
|
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> assumes that all songs are in <SPAN CLASS="textbf">4/4</SPAN> and places that
|
|
MIDI event at offset 0 in the Meta track.
|
|
|
|
<P>
|
|
The T<SMALL>IME</SMALL>S<SMALL>IG</SMALL> value is remembered by G<SMALL>ROOVE</SMALL>s and is
|
|
properly set when grooves are switched. You should probably have a
|
|
time signature in any groove library files you create (the supplied
|
|
files all do).
|
|
|
|
<P>
|
|
The common time signatures “common” and “cut” are supported. They
|
|
are translated by
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> to <SPAN CLASS="textbf">4/4</SPAN> and <SPAN CLASS="textbf">2/2</SPAN>.

Internally,
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> tracks its position in a song according to beats.
|
|
For example, in a <SPAN CLASS="textbf">4/4</SPAN> piece the beat position is
|
|
incremented by 4 after each bar is processed. For the most part, this
|
|
works fine; however, there are some conditions when it would be nice
|
|
to manually adjust the beat position:
|
|
|
|
<P>
|
|
|
|
<UL>
|
|
<LI>Insert some extra (silent) beats at the end of bar to simulate a pause,
|
|
|
|
<P>
|
|
</LI>
|
|
<LI>Delete some beats to handle a “short” bar.
|
|
|
|
<P>
|
|
</LI>
|
|
<LI>Change a pattern in the middle of a bar.
|
|
|
|
<P>
|
|
</LI>
|
|
</UL>
|
|
|
|
<P>
|
|
Each problem will be dealt with in turn. In <A HREF="#eg-pause">this
|
|
example</A> a pause is simulated at the end of bar
|
|
10. One problem with this logic is that the inserted beat will be
|
|
silent, but certain notes (percussive things like piano) often will
|
|
continue to sound (this is related to the decay of the note, not that
|
|
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> has not turned off the note). Frankly, this really doesn't
|
|
work too well ... which is why the F<SMALL>ERMATA</SMALL>
|
|
(<A HREF="#fermata">details here</A>) was added.

In <A HREF="#eg-mixed">this example</A> the problem of
|
|
the “short bar” is handled. In this example, the sheet music has the
|
|
majority of the song in <SPAN CLASS="textbf">4/4</SPAN> time, but bar 4 is in
|
|
<SPAN CLASS="textbf">2/4</SPAN>. This could be handled by setting the T<SMALL>IME</SMALL>
|
|
setting to 2 and creating some different patterns. Forcing silence on
|
|
the last 2 beats and backing up the counter is a bit easier.

|

Finally in <A HREF="#eg-overlap">this example</A>, the problem of
|
|
overlapping bars is handled. We want to change the G<SMALL>ROOVE</SMALL>
|
|
in the middle of a bar. So, we create the third bar two times. The first one
|
|
has a “z!” (silence) for beats 3 and 4; the second has “z!” for beats 1 and 2. This
|
|
permits the two halves to overlap without conflict. The B<SMALL>EAT</SMALL>A<SMALL>DJUST</SMALL>
|
|
forces the two bars to overlap completely.

A “fermata” or “pause” in written music tells the musician to hold
|
|
a note for a longer period than the notation would otherwise indicate.
|
|
In standard music notation it is represented by a
|
|
“<!-- MATH
|
|
$\rotatebox{270}{\textbf{(\raisebox{.5ex}{.}}}$
|
|
-->
|
|
<IMG

|
|
ALT="\rotatebox{270}{\textbf{(\raisebox{.5ex}{.}}}">”
|
|
above a note.
|
|
|
|
<P>
|
|
To indicate all this
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> uses a command like:
|
|
|
|
<P>
|
|
|
|
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
|

<B>Fermata 1 1 200 </B>
|
|
|

</td></tr>
|
|
</Table>
|
|
|
|
<P>
|
|
Note that there are three parts to the command:
|
|
|
|
<P>
|
|
|
|
<OL>
|
|
<LI>The beat offset from the current point in the score to apply the
|
|
“pause”. The offset can be positive or negative and is calculated
|
|
from the current bar. Positive numbers will apply to the next bar;
|
|
negative to the previous. For offsets into the next bar you use
|
|
offsets starting at “0”; for offsets into the previous bar an
|
|
offset of “-1” represents the last beat in that bar.
|
|
|
|
<P>
|
|
For example, if you were in <SPAN CLASS="textbf">4/4</SPAN> time and wanted the
|
|
quarter note at the end of the next bar to be paused, you would use
|
|
an offset of 3. The same effect can be achieved by putting the
|
|
F<SMALL>ERMATA</SMALL> command after the bar and using an offset of -1.
|
|
|
|
<P>
|
|
</LI>
|
|
<LI>The duration of the pause in beats. For example, if you have a
|
|

Here <A HREF="#egpause2">the second example</A> shows
|
|
the first four bars of a popular torch song. The problem with the
|
|
piece is that the first beat of bar four needs to be paused, and the
|
|
accompaniment style has to switch in the middle of the bar. The
|
|
example shows how to split the fourth bar with the first beat on one
|
|
line and the balance on a second. The “z!”s are used to “fill in”
|
|
the 4 beats skipped by the B<SMALL>EAT</SMALL>A<SMALL>DJUST</SMALL>.

This command works by adjusting the global tempo in the MIDI meta
|
|
track at the point of the fermata. In most cases you can put more than
|
|
one F<SMALL>ERMATA</SMALL> command in the same bar, but they should be in beat
|
|
order (no checks are done). If the F<SMALL>ERMATA</SMALL> command has a
|
|
negative position argument, special code is invoked to remove any
|
|
note-on events in the duration specified, after the start of the
|
|
beat.<A NAME="tex2html60"
|
|
HREF="#foot7211"><SUP><SPAN CLASS="arabic">16</SPAN>.<SPAN CLASS="arabic">2</SPAN></SUP></A> This means that extra rhythm notes will
|
|
not be sounded--probably what you expect a held note to sound like.

This command was born of the need to simulate a “cut” or, more
|
|
correctly, a “caesura”. This is indicated in music by two parallel
|
|
lines put at the top of a staff indicating the end of a musical
|
|
thought. The symbol is also referred to as “railroad tracks”.
|
|
|
|
<P>
|
|
The idea is to stop the music on all tracks, pause briefly, and
|
|
resume.<A NAME="tex2html61"

<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> provides the C<SMALL>UT</SMALL> command to help deal with this
|
|
situation. But, before the command is described in detail, a
|
|
diversion: just how is a note or chord sustained in a MIDI file?
|
|
|
|
<P>
|
|
Assume that a
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> input file (and the associated library)
|
|
files dictates that some notes are to be played from beat 2 to beat 4
|
|
in an arbitrary bar. What

<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> does is:

such as <SMALL>STRUM</SMALL>, <SMALL>ARTICULATE</SMALL>, <SMALL>RTIME</SMALL>, etc.,

|

</LI>

You may think that a given note starts on beat 2 and ends (using
|
|
<SMALL>ARTICULATE 100</SMALL>) right on beat 3--but you would most likely be
|
|
wrong. So, if you want the note or chord to be “cut”, what point do
|
|
you use to instruct
|
|
<FONT Face="Serif" Color="Navy"><I>MMA</I></FONT> correctly? Unfortunately, the simple answer
|
|
is “it depends”. Again, the answers will consist of some examples.
|
|
|
|
<P>
|
|
In this first case you wish to stop the track in the middle of the last
|
|
bar. The simplest answer is:
|
|
|
|

<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>

Unfortunately, this will “almost” work. But, any chords which are
|
|
longer than one or two beats may continue to sound. This, often, gives
|
|
a “dirty” sound to the end of the piece. The simple solution is to
|
|
add to the end of the piece:

Depending on the rhythm you might have to fiddle a bit with the cut
|
|
value. But, the example here puts a “all notes off” message in all
|
|
the active tracks at the start of beat 3. The exact same result can be
|
|
achieved by placing:
|
|
|
|

|
<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>

<P>

<SPAN CLASS="textit">before</SPAN> the final bar.
|
|
|

<P>
|

In this second example a tiny bit of silence is desired between bars 4 and
|
|
5 (this might be the end of a musical introduction). The following bit should
|
|
work:

|

In this case the “all notes off” is placed at the end of bar 4 and
|
|
two-tenths of a beat is inserted at the same location. Bar 5 continues
|
|
the track.
|
|
|
|
<P>
|
|
The final example show how you might combine <SMALL>CUT</SMALL> with
|
|
<SMALL>FERMATA</SMALL>. In this case the sheet music shows a caesura after the
|
|
first quarter note and fermatas over the quarter notes on beats 2, 3
|
|
and 4.
