FL Flanger, HRM Harmonist | Boss Audio Systems GT-6B instruction

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.”
