Sequences
</H1>

<P>
Patterns by themselves don't do much good. They have to be combined into
sequences to be of any use to you or to 
<FONT Face="Serif"  Color="Navy"><I>MMA</I></FONT> .

<P>

<H1><A NAME="SECTION00510000000000000000">
Defining Sequences</A>
</H1>

<P>
A S<SMALL>EQUENCE</SMALL> command sets the pattern(s) used in creating
each track in your song:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Track Sequence Pattern1 Pattern2 ...</B> 
   
	    </td></tr>
      </Table>

<P>
``Track'' can be any valid track name: ``Chord'', ``Walk'',
``Walk-Sus'', ``Arpeggio-88'', etc.

<P>
All pattern names used when setting a sequence need to be defined when
this command is issued; or you can use what appears to be a pattern
definition right in the sequence command by enclosing the pattern
definition in a set of curly brackets ``{ }''.

<P>

		<Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="#efefef" Border=3>
		   <tr><td Align="CENTER" BGColor="White">
	      <SPAN  CLASS="textbf"><BIG CLASS="XLARGE">Simple Sequence</BIG></SPAN>  <A NAME="eg:seq1"></A>	
	 	   </tr> </td>
           <tr> <td >
		     
  
      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>

<BR>

<BR>&nbsp;&nbsp;&nbsp; Sequence Snare4 
<BR>&nbsp;&nbsp;&nbsp; Tone Snaredrum1 
<BR>

	    </td></tr>
      </Table>
 
	
	       </td> </tr>
        </Table>

<P>

<P>
<A HREF="#eg:seq1">This example</A> creates a 2 bar
pattern. The Drum, Chord and Bass patterns repeat on every bar; the
Drum-1 sequence repeats after 2 bars. Note how the Arpeggio pattern is
defined at run-time.<A NAME="tex2html32"
  HREF="#foot2590"><SUP><SPAN CLASS="arabic">5</SPAN>.<SPAN CLASS="arabic">1</SPAN></SUP></A>
<P>
If there are fewer patterns than S<SMALL>EQ</SMALL>S<SMALL>IZE</SMALL>, the sequence will be
filled out to correct size. If the number of patterns used is greater
than S<SMALL>EQ</SMALL>S<SMALL>IZE</SMALL> (see
<A HREF="node29.html#sec-directives">directives</A>) a warning
message will be printed and the pattern list will be truncated.

<P>
When defining longer sequences, you can use the ``repeat'' symbol, a
single ``/'', to save typing. For example, the following two lines are
equivalent:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Bass Sequence Bass1 Bass1 Bass2 Bass2 
<BR>
Bass Sequence Bass1 / Bass2 /   </B> 
   
	    </td></tr>
      </Table>

<P>
<A NAME="sequence-clear"></A>
<P>
The special pattern name ``-'' (no quotes, just a single hyphen), or a
single ``z'' can be used to turn a track off. For example, if you have
set the sequences in <A HREF="#eg:seq1">this example</A>
and decide to delete the Bass halfway though the song you could:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Bass Sequence -   </B> 
   
	    </td></tr>
      </Table>

<P>
The special sequences, ``-'' or ``z'', are also the equivalent of a
rest or ``tacet'' sequence. For example, in defining a 4 bar sequence
with a bass pattern on the first 3 bars and a walking bass on bar
4 you might do something like:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Bass Sequence Bass4-13 / / z 
<BR>
Walk Sequence z / / Walk4-4   </B> 
   
	    </td></tr>
      </Table>

<P>
If you already have a sequence defined<A NAME="tex2html33"
  HREF="#foot2492"><SUP><SPAN CLASS="arabic">5</SPAN>.<SPAN CLASS="arabic">2</SPAN></SUP></A> you can repeat or copy the existing pattern by
using a single ``*'' as the pattern name. This is useful when you are
modifying an existing sequence.

<P>
For example, assume that we have created a four bar G<SMALL>ROOVE</SMALL>
called ``Neato''. Now, we want to change the C<SMALL>HORD</SMALL> pattern to
use for an introduction ... but, we really only want to change the
fourth bar in the pattern:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Groove Neato 
<BR>
Chord Sequence * * * {1 2 90} 
<BR>
Defgroove NeatoIntro   </B> 
   
	    </td></tr>
      </Table>

<P>
When a sequence is created a series of pointers to the existing
patterns are created. If you change the definition of a particular
pattern later in your file the new definition will have <SPAN  CLASS="textit">no</SPAN>
effect on your existing sequences.

<P>
Sequences are the workhorse of 
<FONT Face="Serif"  Color="Navy"><I>MMA</I></FONT> . With them you can set up many
interesting patterns and variations. This chapter should certainly
give more detail and many more examples.

<P>
Seqeuence definitions can get quite long and may need multiple
lines. You can do this by using `` \'' marked continuation lines. Or, to
make it possible to have comments at the end of lines, 
<FONT Face="Serif"  Color="Navy"><I>MMA</I></FONT>  will
parse S<SMALL>EQUENCE</SMALL> lines and attempt to join lines together until a
matching number of ``{''s and ``}''s are found. One caution: in
order for this feature to work with multi-bar sequences you must have
non-matching braces on a line. For example, this will work:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Chord Sequence {1 4 90; 
<BR>
3 4 90} { 1 1 90}   </B> 
   
	    </td></tr>
      </Table>

<P>
This will <SPAN  CLASS="textit">not work</SPAN>:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Chord Sequence {1 4 90 }&nbsp; <IMG
 WIDTH="21" HEIGHT="21" ALIGN="BOTTOM" BORDER="0"
 SRC="img2.png"
 ALT="\includegraphics[height=2.5ex]{/home/bob/src/bv/mma/docs/images/stop.eps}">
<BR>      {1 1 90}   </B> 
   
	    </td></tr>
      </Table>

<P>
In the second example 
<FONT Face="Serif"  Color="Navy"><I>MMA</I></FONT>  reads the first ``{1 4 90}'' and figures
that's the end of the sequence. When if finds the next line, it's
totally confused.

<P>
The following commands help manipulate sequences in your creations:

<P>

<H1><A NAME="SECTION00520000000000000000"></A>  <A NAME="sec-seqclear"></A>
<BR>
SeqClear
</H1>

<P>
This command clears all existing sequences from memory. It is useful
when defining a new sequence and you want to be sure that no
``leftover'' sequences are active. The command:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>SeqClear  </B> 
   
	    </td></tr>
      </Table>

<P>
deletes all sequence information, with the important exception that
S<SMALL>OLO</SMALL> and S<SMALL>TICKY</SMALL> (<A HREF="node6.html#sect-sticky">here</A>) tracks are ignored.

<P>
Alternately, the command:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Drum SeqClear  </B> 
   
	    </td></tr>
      </Table>

<P>
deletes <SPAN  CLASS="textit">all</SPAN> drum sequences. This includes the track ``Drum'',
``Drum1'', etc.

<P>
If you use a sub-track:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Chord-Piano SeqClear  </B> 
   
	    </td></tr>
      </Table>

<P>
only the sequence for that track is cleared.<A NAME="tex2html34"
  HREF="#foot2591"><SUP><SPAN CLASS="arabic">5</SPAN>.<SPAN CLASS="arabic">3</SPAN></SUP></A>
<P>
In addition to clearing the sequence pattern, the following other
settings are restored to a default condition:

<P>

<UL>
<LI>Track Invert setting,

<P>
</LI>
<LI>Track Sequence Rnd setting,

<P>
</LI>
<LI>Track MidiSeq setting,

<P>
</LI>
<LI>Track octave,

<P>
</LI>
<LI>Track voice,

<P>
</LI>
<LI>Track Rvolume,

<P>
</LI>
<LI>Track Volume,

<P>
</LI>
<LI>Track RTime,

<P>
</LI>
<LI>Track RDuration, 

<P>
</LI>
<LI>Track Strum.

<P>
</LI>
</UL>

<P>
CAUTION: It is not possible to clear only  a track like D<SMALL>RUM</SMALL> or
C<SMALL>HORD</SMALL> using this command. The command

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Chord SeqClear  </B> 
   
	    </td></tr>
      </Table>

<P>
resets <SPAN  CLASS="textit">all</SPAN> C<SMALL>HORD</SMALL> tracks, whereas the command:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Chord-Foo SeqClear  </B> 
   
	    </td></tr>
      </Table>

<P>
resets the C<SMALL>HORD-</SMALL>F<SMALL>OO</SMALL> track. If you need to clear <SPAN  CLASS="textit">only</SPAN>
the C<SMALL>HORD</SMALL> track use the ``-'' option.

<P>

<H1><A NAME="SECTION00530000000000000000"></A>
  
   <A NAME="seqrnd"></A>
<BR>
SeqRnd
</H1>

<P>
Normally, the patterns used for each bar are selected in order. For
example, if you had a sequence:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Drum-2 Sequence P1 P2 P3 z  </B> 
   
	    </td></tr>
      </Table>

<P>
bar 1 would use ``P1'', bar 2 ``P2'', etc. However, it is quite
possible (and fun and useful) to insert a randomness to the order of
sequences. 
<FONT Face="Serif"  Color="Navy"><I>MMA</I></FONT>  can achieve this in three different ways:

<P>

<OL>
<LI>Separately for each track:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Drum-Snare SeqRnd On  </B> 
   
	    </td></tr>
      </Table>

<P>
</LI>
<LI>Globally for all tracks:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>SeqRnd On  </B> 
   
	    </td></tr>
      </Table>

<P>
</LI>
<LI>For a selected set of tracks (keeping the tracks synchronized):

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>SeqRnd Drum-Snare Chord-2 Chord-3  </B> 
   
	    </td></tr>
      </Table>

<P>
</LI>
</OL>

<P>
To disable random sequencing:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>SeqRnd Off
<BR>
Drum SeqRnd Off  </B> 
   
	    </td></tr>
      </Table>

<P>
To illustrate the different effects you can generate, assume that you
have a total of four tracks defined: Drum-Snare, Drum-Low, Chord and
Bass; your sequence size is 4 bars; and you have created some type of
sequence for each track with a commands similar to:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Drum-Snare Sequence D1 D2 D3 D4 
<BR>
Drum-Low Sequence D11 D22 D33 D44 
<BR>
Chord Sequence C1 C2 C3 C4 
<BR>
Bass Sequence B1 B2 B3 B4  </B> 
   
	    </td></tr>
      </Table>

<P>
With no sequence randomization at all, the tracks will be be processed
as:

<P>

</TR>
</TABLE>
</BLOCKQUOTE>

<P>
Next, assume we have set sequence randomization with:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>SeqRnd On  </B> 
   
	    </td></tr>
      </Table>

<P>
Now, the sequence may look like:

</TR>
</TABLE>
</BLOCKQUOTE>

<P>
Note that the randomization keeps the different sequences together:
Drum sequences D3 and D33 are always played with Chord sequence C3,
etc.

<P>
Next, we will set randomization for a Drum and Chord track only:

<P>

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

</BLOCKQUOTE>

<P>
In this case there is no relationship between any of the randomized
tracks.

<P>
Finally, it is possible to set a ``global'' randomization for a
selected set of tracks. In this case we will set the Drum tracks only:

<P>
Note that the drum sequences always ``line up'' with each other and
the Chord and Bass sequences follow in the normal order.

<P>
The S<SMALL>EQ</SMALL>C<SMALL>LEAR</SMALL> command will disable all sequence
randomization. The S<SMALL>EQ</SMALL> command will disable ``global'' (for all
tracks) randomization.

<P>
When S<SMALL>EQ</SMALL>R<SMALL>ND</SMALL> is enabled each sequence for the track (or globally) has an equal chance
of being selected. There are times when you may want to change this behavior. For example,
you might have a sequence like this:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Chord Sequence C1  C2  C3  C4  </B> 
   
	    </td></tr>
      </Table>

<P>
and you feel that the patterns C1 and C2 need to be used twice as often as C3 and C4.
Simple:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>Chord SeqRndWeight 2 2 1 1  </B> 
   
	    </td></tr>
      </Table>

<P>
Think of the random selection occurring like selecting balls out of bag. The S<SMALL>EQ</SMALL>R<SMALL>ND</SMALL>W<SMALL>EIGHT</SMALL>
command ``fills up the bag''. In the above case, there will be two C1 and C2 balls, one C3 and C4 ball--
for a total of six balls.

<P>
This command can be used in both a track and global context.

<P>
The effects are saved in G<SMALL>ROOVES</SMALL>.

<P>
S<SMALL>EQ</SMALL>C<SMALL>LEAR</SMALL> will reset both global and track contexts to the default (equal) condition.

<P>

<H1><A NAME="SECTION00550000000000000000">
SeqSize</A>
</H1>

<P>
The number of bars in a sequence are set with the ``SeqSize'' command.
For example:

<P>

      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
    <B>SeqSize 4  </B> 
   
	    </td></tr>
      </Table>

<P>
sets it to 4 bars. The SeqSize applies to all tracks.

<P>
This command resets the <SPAN  CLASS="textit">sequence counter</SPAN> to 1.

<P>
If some sequences have already been defined, they will be truncated or
expanded to the new size. Truncation is done by removing patterns from
the end of the sequence; expansion is done by duplicating the sequence
until it is long enough.

<DD>If you run 
<FONT Face="Serif"  Color="Navy"><I>MMA</I></FONT>  with the ``-s'' option
  you'll see pattern names in the format ``_1''. The leading
  underscore indicates that the pattern was dynamically created in the
  sequence.

<DD>In reality there is
  always a sequence defined for every track, but it might be a series
  of ``rest'' bars.

<DD>It is probably
  easier to use the command: 
      <Table Hspace="40%" CellSpacing=0 CellPadding=10 BGColor="OldLace" Border=3>
        <tr><td>
   <B>Chord-Piano Sequence -  </B> 
   
	    </td></tr>
      </Table>
 if that is
  what you want to do. In this case <SPAN  CLASS="textit">only</SPAN> sequence pattern is
  cleared.
