ivibrte

A realistic string tone emulation achieved by complex wave FM
modulation. The three components of the complex wave are
independent in their modulation indices and c:m ratios, thus
allowing great and precise control over the emerging spectra. An
attack noise portion and a vibrato add to the realism of the
design. 

The timeout flow-control statement of the csound language is used
to mix the attack, vibrato and normal portions of the instrument.
The parameters 'inoisdur' and 'ivibdel' control the duration time
of the attack noise and the delay time of the vibrato respect-
ively. This design can doubtlessly be put to refined use in other
contexts. (Schottstaedt 1977; Vercoe 1993: morefiles/string.orc)
