Ac.guitar Simulator; Slow Gear; Octave; Pitch Shifter - Boss GT-1 Parameter Manual / Sound List

EFFECT

AC.GUITAR SIMULATOR

This effect simulates the tonal character of an acoustic guitar.
Parameter Value Explanation
BODY
0–100 Adjusts the body resonance.
Specifies the sense of volume for the low-
LOW -50–+50
frequency range.
Specifies the sense of volume for the high-
HIGH -50–+50
frequency range.
LEVEL 0–100 Specifies the volume of the effect.

SLOW GEAR

This produces a volume-swell effect ("violin-like" sound).
Parameter Value
SENS 0–100
RISE TIME
0–100
LEVEL 0–100

OCTAVE

This adds a note one octave lower and a note two octaves lower,
creating a richer sound.
Parameter Value
-1 OCT
0–100
-2 OCT 0–100
D.LEVEL
0–100
(DIRECT LEVEL)
8
Explanation
Adjusts the sensitivity of the slow gear. When
it is set to a lower value, the effect of the slow
gear can be obtained only with a stronger
picking, while no effect is obtained with a
weaker picking. When the value is set higher,
the effect is obtained even with a weak picking.
Adjusts the time needed for the volume to
reach its maximum from the moment you
begin picking.
Adjusts the volume of the effect sound.
Explanation
Adjusts the volume of the sound one octave
below.
Adjusts the volume of the sound two octaves
below.
Adjusts the volume of the direct sound.

PITCH SHIFTER

This effect changes the pitch of the original sound (up or down)
within a range of two octaves.
Parameter Value
PITCH -24–+24
D.LEVEL
0–100
(DIRECT LEVEL)
FINE -50–+50
0 ms–300 ms,
PRE DELAY
BPM ˜ – ¸
E.LEVEL 0–100
FEEDBACK 0–100

HARMONIST

Harmonist is an effect where the amount of shifting is adjusted
according to an analysis of the guitar input, allowing you to create
harmony based on diatonic scales.
* Because of the need to analyze the pitch, chords (two or more
sounds played simultaneously) cannot be played. Be sure to
mute all the other strings and play only one note at a time.
* When you are to play the next string while a certain sound is
still playing, mute the previous sound and then play the next
one with a clear attack. If the unit cannot detect the attack, it
may not sound correctly.
* The sensitivity may vary according to the guitar's TONE knob
and pickup type.
Parameter Value
HARMONY
-2 oct–+2 oct
KEY C (Am)–B
(MASTER KEY) (G#m)
Explanation
Adjusts the amount of pitch shift
(the amount of interval) in semitone
steps.
Adjusts the volume of the direct
sound.
Make fine adjustments to the
interval. The amount of the change
in the Fine 100 is equivalent to that
of the Pitch 1.
Adjusts the time from when the
direct sound is heard until the pitch
shifted sounds are heard. Normally
you can leave this set at 0 ms.
* When set to BPM, the value
of each parameter will be set
according to the value of the
"MASTER BPM" specified for each
patch. This makes it easier to
achieve effect sound settings that
match the tempo of the song.
* If, due to the tempo, the time
is longer than the range of
allowable settings, it is then
synchronized to a period either
1/2 or 1/4 of that time.
* BPM (beats per minute) indicates
the number of quarter note beats
that occur each minute.
Adjusts the volume of the pitch
shifter.
Adjusts the feedback amount of the
pitch shift sound.
Explanation
This determines the pitch of the sound added
to the input sound, when you are making a
harmony.
It allows you to set it by up to 2 octaves higher
or lower than the input sound.
The key setting corresponds to the key of the
song (#, b) as follows.
