<U>DESCRIPTION</U></H4>
where the argument within the parentheses may be an expression. These value
converters sample a global random sequence or return information about
a stored function table. The result can be a term in a further expression.
<BR>
<H4>
<U>PERFORMANCE</U></H4>
<B>rnd(x)</B> returns
a random number in the unipolar range 0 to x. The form <B>irnd(x)</B> returns
at i-rate.
<BR>
The form <B>krnd(x) </B>returns at k-rate
<P><B>birnd(x)</B> returns a
random number in the bipolar range -x to x.
<BR>
These units obtain values from a global psuedo-random number generator,
<BR>
then scale them into the requested range. The single global generator
will
<BR>
thus distribute its sequence to these units throughout the performance,
<BR>
in whatever order the requests arrive. The form <B>ibirnd(x)</B> returns
at i-rate.
<BR>
The form <B>kbirnd(x) </B>returns at k-rate
<P><B>ftlen(x) </B> returns the
size (no. of points, excl. guard point) of stored function table no. x.
<BR>
While most units referencing a stored table will automatically take its
size
<BR>
into account (so tables can be of arbitrary length), this function reports
<BR>
the actual size if that is needed.
<P><B>ftlptim(x)</B> returns the loop segment
start-time (in seconds) of stored function table no. x.
<BR>
This reports the duration of the direct recorded attack and decay parts
of a
<BR>
sound sample, prior to its looped segment. Returns zero (and a warning
<BR>
message) if the sample does not contain loop points.
