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.

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.
