WAH-WAH
Simulates the classic guitar effect, that takes the name from its characteristic
sound. It is in short a filter which is "shifted" along the frequency, so as to
create a particular effect.
−
Type: sets the filter control type,
•
Auto: the cutoff frequency moves continuously and automatically.
•
Touch: the cutoff frequency is set according to the dynamic, i.e. the
pressure on the keyboard. The higher the dynamic (pressure), the
higher the frequency.
•
Pedal: an external pedal sets the cutoff frequency. It must be an
expression pedal (NO switch) and it must be connected to the
[FOOT CONTROLLER 1], [FOOT CONTROLLER 2], [SOSTENUTO] or [SOFT] connectors. Furthermore, the
function must be assigned to the pedal, through the Pedals page under the FUNCTION menu (see par.5.1)
−
Top: sets the filter's maximum cutoff frequency.
−
Bottom: sets the filter's minimum cutoff frequency.
−
Resonance: sets the filter's resonance curve, controlling how the frequencies close to the cutoff frequency are
magnified. The higher the resonance value, the narrower the interval in which the frequencies are magnified; at the
same time, the narrower the interval, the louder are the frequencies within that interval.

FilterType: select the type of filter,
•
LP: low-pass filter, passes low-frequency signals and attenuates signals with frequencies higher than the cutoff
frequency.
•
BP: band-pass filter, attenuates all frequencies outside a certain range (band); the centre of this range is the
cutoff frequency.
•
HP: high-pass filter, passes high-frequency signals and attenuates signals with frequencies lower thatn the cutoff
frequency.

Speed (with Type=Auto): sets the speed at which the filter moves while in Auto mode.
