The li algorithm</H4>
<PRE>{li val1 val2 duration(s)}</PRE>
The <B>li</B> is for line. The values given after <B>li</B> will define
the departure and arrival points of a straight line. Last element in the
list is the duration in number of events or seconds (s)
<P>Values can be:
<OL>
<LI>
<B>a real number.</B></LI>
<PRE>{li 4.567 10 10s}
{li 4 0 30}</PRE>
<LI>
<B>a CECILIA irate variable.</B> Any irate variable from the CECILIA interface
can be used (sliders, toggles, option) by including the name of the variable
between <B>[]</B> brackets. The substitution is done before the score is
pre-compiled.</LI>
<PRE>{li [blue] [black] 30s}</PRE>
where <B>blue</B> and <B>black</B> have been defined as irate variables
in the CECILIA interface.
<BR>
<LI>
<B>a Cybil function. </B>Any Cybil function can be used to generate a value
for the sequencer. Each time the value is needed, the function is evaluated
(see functions further).</LI>
<PRE>{li {ran f .5 3.3} 4 30s}</PRE>
At computation time, the departure value of the line will be randomly selected
between .5 and 3.3. The arrival point will always be <B>4</B>.</OL>
