Chapter 7. Adding Effects
07: AUTO WAH
The Auto Wah cyclically controls a filter to create cyclic
change in timbre.
fig.MFX-07
Filter (Filter Type)
Select the type of filter.
LPF : The wah effect will be applied over a wide frequency
range.
BPF : The wah effect will be applied over a narrow frequency
range.
Sens (Sensitivity)
Adjust the sensitivity with which the filter is controlled.
Manual #
Adjust the center frequency from which the effect is applied.
Peak
Adjust the amount of the wah effect that will occur in the
area of the center frequency. Lower settings will cause the
effect to be applied in a broad area around the center
frequency. Higher settings will cause the effect to be applied
in a more narrow range.
Rate #
Adjust the frequency of the modulation.
Depth
Adjust the depth of the modulation.
Level (Output Level)
Adjust the output level.
08: ROTARY
The Rotary effect simulates the sound of the rotary speakers
often used with the electric organs of the past. Since the
movement of the high range and low range rotors can be set
independently, the unique type of modulation characteristic
of these speakers can be simulated quite closely. This effect is
most suitable for electric organ Patches.
fig.MFX-08
LowSlow (Low Frequency Slow Rate)
Adjust the slow speed (SLOW) of the low frequency rotor.
LowFast (Low Frequency Fast Rate)
Adjust the fast speed (FAST) of the low frequency rotor.
LowAccl (Low Frequency Acceleration)
Adjust the time it takes the low frequency rotor to reach the
newly selected speed when switching from fast to slow (or
slow to fast) speed. Lower values will require longer times.
Low Lvl (Low Frequency Level)
Adjust the volume of the low frequency rotor.
Hi Slow (High Frequency Slow Rate)
Adjust the slow speed (SLOW) of the high frequency rotor.
Hi Fast (High Frequency Fast Rate)
Adjust the fast speed (FAST) of the high frequency rotor.
Hi Accl (High Frequency Acceleration)
Adjust the time it takes the high frequency rotor to reach the
newly selected speed when switching from fast to slow (or
slow to fast) speed. Lower values will require longer times.
Hi Lvl (High Frequency Level)
Adjust the volume of the high frequency rotor.
Separation
Adjust the spatial dispersion of the sound.
Speed #
Simultaneously switch the rotational speed of the low
frequency rotor and high frequency rotor.
SLOW : Slow down the rotation to the specified speed (the
Low Slow/Hi Slow values).
FAST : Speed up the rotation to the specified speed (the Low
Fast/Hi Fast values).
For details refer to “Using a Pedal Switch to Modify the
Speed of the Rotary Effect” (p. 199).
