Tuning and Pitch Parameters
 Analog knob: Simulates the instability of analog circuitry found in vintage vocoders.
Analog alters the pitch of each note randomly. This behavior is much like that of
polyphonic analog synthesizers. The Analog knob controls the intensity of this
random detuning.
 Tune: Defines the range of detuning.
 Glide: Glide determines the time it takes for the pitch to slide from one note to
another (portamento).
 Bend Range: Determines the pitch bend modulation range in semitones.
Cutoff and Resonance
 Cutoff: Sets the cutoff frequency of the lowpass filter. As you turn this knob to the
left, an increasing number of high frequencies is filtered from the signal.
 Resonance: Turning up Resonance leads to an emphasis of the frequency area
surrounding the frequency defined by the Cutoff parameter. The filter is used for
rough signal shaping, before the signal is articulated by the vocoding circuits.
Tip: Set Cutoff as high as possible, and add a little Resonance to achieve a nice, brilliant
high-end.
