<U>DESCRIPTION</U></H4>
<B>wgpluck2</B> is an implementation of the physical model of the plucked
string, with control over the pluck point, the pickup point and the filter. <B>
repluck</B> is the same operation, but with an additional audio signal
used to excite the 'string'. Both opcodes are based on the Karplus-Strong
algorithms.
<H4>
<U>INITIALIZATION</U></H4>
<I>icps -</I> The string plays at <I>icps</I> pitch.
<P><I>iplck - </I>The point of pluck is<I> iplk</I>, which is a fraction
of the way up the string (0 to 1). A pluck point of zero means no
initial pluck.
<H4>
<U>PERFORMANCE</U></H4>
<I>xamp</I> is the gain. and <I>kpick</I> is what proportion of the way
along the string to sample the output. The relection at the bridge
is controlled by the reflection coefficient <I>krefl</I>, where 1 means
total reflection and 0 is totally dead.
