Chapter 4 The Effects Explained
■ FL: Flanger
This produces a flanging effect that gives a sort of “twisting”
character to the sound. Although it resembles the phaser
effect, the flanger yields a colder, more metallic twisting
effect.
Parameter Value
Rate 0–100, BPM –BPM
Depth 0–100
Manual 0–100
Resonance 0–100
Separation 0–100
Level 0–100
Rate
This sets the rate of the flanging effect.
* 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 modulation depth. The twisting effect spreads
out more as the value is increased.
Manual
Adjusts the center frequency for the flanger effect. The
twisting effect occurs in a higher range of frequencies as the
value is increased.
Resonance
Adjusts the resonance (the amount of feedback). Increasing the
value emphasizes the effect, creating a more unusual sound.
Separation
Adjusts the amount of separation. Raising the value increases
the separation between the left and right sides.
Level
Adjusts the volume.
■ HRM: Harmonist
This effect adjusts the shift in pitch according to an analysis
of the pitch of the bass input, allowing you to create
harmonics based on Diatonic or user definable scales.
* Because of the need to analyze the pitch, chords (two or more
sounds played simultaneously) cannot be played.
Parameter Value
Voice 1-Voice, 2-Mono, 2-Stereo
Harmony -2oct–+2oct, Scale 1–Scale29
Pre Delay 0 ms–300 ms, BPM –BPM
Feedback 0–100
Level 0–100
Key C(Am)–B(G#m)
Direct Level 0–100
Voice
This selects the number of voices for the pitch shift sound
(harmony).
1-Voice:
One-voice pitch-shifted sound output in mono.
2-Mono:
Two-voice pitch-shifted sound (HR1, HR2) output in mono.
2-Stereo:
Two-voice pitch-shifted sound (HR1, HR2) output through
the left and right channels.
Harm (Harmony)
This determines the pitch of the sound added to the input
sound, when you are making a harmony. You can have this
sound play up to 2 octaves higher or lower than the input
sound.
When the scale is set to “Scale 1–Scale29,” harmonies
corresponding to the user-set scale are produced.
The following shows the parameters that can be set for User
scales.
User 1–29
DIR C–B
EFF C–B (+/- 2 octave)
“Creating Harmonist Scales (User Scale)” (p. 37)
PreDly (Pre Delay)
Adjusts the time from when the direct sound is played until
the harmonist sounds are produced. Normally, you can leave
this set at “0 ms.”
* 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 [
