Vintage Clav Wah eect
Vintage Clav provides simulations of several classic wah eects, as well as some basic lter
types. The name wah comes from the sound it produces. It has been a popular eect (usually a
pedal eect) with electric guitarists since the days of Jimi Hendrix. The pedal controls the cuto
frequency of a bandpass, lowpass, or—less commonly—highpass lter. Wah wah pedals are also
used extensively with the D6. For information about assigning a controller to the Wah eect, see
Vintage Clav Misc parameters.
Wah eect parameters
•
On/o button: Turns the Wah eect on or o.
•
Mode pop-up menu: Choose a Wah eect type.
•
Classic Wah: This setting mimics the sound of a popular wah pedal with a slight
peak characteristic.
•
Retro Wah: This setting mimics the sound of a popular vintage wah pedal.
•
Modern Wah: This setting mimics the sound of a distortion wah pedal with a constant
Q(uality) Factor setting. The Q determines the resonant characteristics. Low Q values aect
a wider frequency range, resulting in softer resonances. High Q values aect a narrower
frequency range, resulting in more pronounced emphasis.
•
Opto Wah 1: This setting mimics the sound of a distortion wah pedal with a constant
Q(uality) Factor setting.
•
Opto Wah 2: This setting mimics the sound of a distortion wah pedal with a constant
Q(uality) Factor setting.
•
Resonant LP: In this mode, the Wah works as a resonance-capable lowpass lter. At the
minimum pedal position, only low frequencies can pass.
•
Resonant HP: In this mode, the Wah works as a resonance-capable highpass lter. At the
maximum pedal position, only high frequencies can pass.
•
Peak: In this mode, the Wah works as a peak (bell) lter. Frequencies close to the cuto
frequency are emphasized.
•
Range knob: Rotate to set the cuto frequency of the lter. At the extreme left position, Range
limits cuto modulation to a narrow frequency range. To provide a wider control range, turn
the Range knob to the right.
•
Envelope knob: Rotate to determine the sensitivity of the (lter) envelope to incoming note
velocity messages. An auto wah eect is produced by using the integrated envelope follower
function, which controls the depth of lter cuto modulation. In practical terms, this means
that the dynamics of your performance directly control the depth of the Wah eect.
