MIDI Control of the EVB3 Wah Wah Effect
You can choose any MIDI controller number shown in the CC pop-up menu (or channel
aftertouch) to control the Wah Wah effect. You can also teach the Wah Wah to respond
to any incoming message using the Learn function. See Learning EVB3 MIDI Controller
Assignments.
For the most dynamic and musical performance of the Wah Wah effect, consider attaching
an expression pedal to your MIDI master keyboard. Your master keyboard should transmit
MIDI control change #11, which would normally be used to control the EVB3 volume
while playing.
To use an expression pedal to control the Wah Wah
1 Set the Expression knob (to the left of the Volume knob in the silver section) to a value
of 0.
2 Choose controller 11 in the CC pop-up menu.
This allows you to control the Wah Wahs cutoff frequency with the expression pedal—and
saves you the trouble of any further setup procedures on the master keyboard. If step 1
is overlooked, the Expression pedal will be used to control both the EVB3 main volume
and the Wah Wah effect.
Note: Consult the users manual of your keyboard to learn more about use of an expression
pedal.
To define the sensitivity of the Wah Wah to controller movements
µ
Adjust the Range knob.
If you intend to make only slight alterations to the cutoff frequency, choose a small value.
Using the EVB3’s Integrated Distortion Effect
The distortion effect simulates an overdriven two-stage tube amplifier. Its primary role is
to simulate the Leslie amplifier, or whatever amp might be used to feed the Leslie speaker
cabinet.
Type pop-up menu: You can choose from three different tube amplifier models:
Growl: Growl simulates a two-stage tube amplifier. It closely resembles the Leslie
122 Model, the classic partner for the Hammond B3 organ.
Bity: Bity is reminiscent of a bluesy guitar amp.
Nasty: Nasty delivers hard distortions and is suitable for very aggressive sounds.
