Chapter 4 The Effects Explained
Manual
(with Auto)
Sets the point at which the two vowels will be switched.
When set to “50,” an equal length of time is used to switch
Vowel 1 and Vowel 2. When it is set to lower than “50,” the
time for Vowel 1 is shorter. When it is set to higher than “50,”
the time for Vowel 1 is longer.
Level
This sets the volume of the humanizer.
■ T/P: TREMOLO/PAN
This provides a tremolo or auto pan effect.
Parameter Value
Mode Tremolo, Pan
Wave Shape 0–100
Rate 0–100, BPM –BPM
Depth 0–100
Mode
This selects either the tremolo or auto pan.
Tremolo:
This is an effect that cyclically changes the volume.
Pan:
This effect alternately switches the volume levels set for the
left and right sides, making sounds played in stereo appear
to fly back and forth between the speakers.
Wave Shape
This adjusts how changes in volume level are made. When
set to lower values, the change occurs smoothly; the change
becomes progressively more sudden as the value is
increased.
Rate
This adjusts the cycle for the change in volume.
* When set to BPM, the value of each parameter is set according
to the value of the Master BPM (p. 44) specified for each patch.
This makes it easy to achieve effect sound settings that match
the tempo of the song (synchronizing the cycle to one-half or
one-fourth of the BPM when the set cycle rate is increased).
When setting to the BPM, press PARAMETER [
] to
display the Master BPM settings screen.
Depth
Adjusts the depth of the volume change.
■ SYN: Bass Synth
This effect produces a synth bass sound. Two methods are
used, the “Internal Sound Generator method” and the
“Waveform Shaping method.”
Internal Sound Generator Method
The unit detects pitch and attack information in the input
bass sound and causes the internal sound generator to
generate sound. Please note the following points.
* This function does not work properly with chords. Be sure to
mute all the other strings and play single notes.
* If you want to play a string before a previous sound has
stopped, completely mute the previous sound first, and then
play the next string with a firm, clear attack.
* Sounds may not be generated correctly if the unit is unable to
detect the attack.
Waveform Shaping Method
The synth bass sound is created by serial processing of the
input bass sound.

Wave
This selects the type of waveform used as the foundation of
the bass synthesizer.
Square:
A “square wave ( )” is produced by the internal
sound generator.
Saw:
A “saw wave ( )” is produced by the internal sound
generator.
Brass:
Waveform shaping outputs a soft sound with a fast attack
and a sharp edge.
