<hr><a name="_details"></a><h2>Detailed Description</h2>
Four formant synthesis instrument.
<p>
This instrument contains an excitation singing wavetable (looping wave with random and periodic vibrato, smoothing on frequency, etc.), excitation noise, and four sweepable complex resonances.
<p>
Measured formant data is included, and enough data is there to support either parallel or cascade synthesis. In the floating point case cascade synthesis is the most natural so that's what you'll find here.
<p>
Control Change Numbers: <ul>
<li>Voiced/Unvoiced Mix = 2<li>Vowel/Phoneme Selection = 4<li>Vibrato Frequency = 11<li>Vibrato Gain = 1<li>Loudness (Spectral Tilt) = 128</ul>
