Reverb (Green) 217
Formant Reverb
This adds formant filters to the Cirrus Reverb to give the reverb tail more color, and a very distinctive, choir-like
sound. The main purpose of the Formant Reverb, however, is not to create a realistic choir sound, but to give it a
certain character, making it sound more like a synthesizer or Mellotron. The formants also help the reverb cut
through the mix, even at moderate volume levels.
 •Formant Mix
Use this to balance the unfiltered reverb sound against the filtered sound. At zero, the Formant Reverb sounds
identical to the Cirrus Reverb. Turn Formant Mix towards higher values to hear the formant filters.
 •Formant Vowel
Use this to morph continuously between the vowels U, O, A, E and I.
 •Formant Offset
Use this to apply a constant frequency offset to the formant filters. The “voice” character will become more feminine
or childlike when turned to the right, and more masculine when turned to the left.
 •Formant Peak
Controls the resonance, or q-factor, of the two formant bandpass filters and thus the intensity or “sharpness” of the
filters.
