<p>
A guard point is the last position on a function table.
If the length is, say 1024, the table will have 1024+1 (1025) points:
the extra point is the guard point.
</p>
<p>
In any case, for a 1024-point table, the first point is index 0 and the
last 1023; index 1024 is not really used)
</p>
<p>
The reason for a guard-point is that some opcodes interpolate
to obtain a table value, in which case, when the table index is
say, 1023.5, we need the value of the 1024 pos in order to interpolate.
</p>
<p>
There are two ways of filling this point (writing the value that goes
in it):
</p>
<div class="orderedlist">
<ol class="orderedlist" type="1">
<li class="listitem">
<p>
Default way: by copying the value of the 1st point in the table
</p>
</li>
<li class="listitem">
<p>
Extended Guard-Point: extending the contour of the table (continuing to
calculate the table for one extra point)
</p>
</li>
</ol>
</div>
<p>
In general the first mode is used for wrap-around applications, such as
an oscillator (which loops continuously reading the table). The second
use is for one-shot readouts, such as envelopes, where the last point
needs to be interpolated correctly following the table contour (we are not
looping back to the beginning of the table)
