Klatt Voice
A synth that SINGS. Play the Keyboard and the Klatt Voice sings the vowel /a/ — a saw oscillator (its pitch from the keys, its level shaped by an ADSR) is the glottal source, and the Klatt Voice turns it into a voice with its formant bank. Dial F1/F2/F3 on the Voice to morph the vowel (/a/ 730·1090·2440 -> /i/ 270·2290·3010), raise Frication for a breathy hiss, or Breath for aspiration. The source-filter synthesis half of the excitation arc: to drive the vowel from a real voice instead, see the Vocal Resynthesis rig. A FUNCTIONAL preset (explicit nodes + connections), palette-only.
