Chapter 9 Parameters Guide COSM GUITAR
With the Alternate Tuning function, you can convert the pitch of
each individual string of a COSM guitar, without changing the
guitar’s actual tuning.
Alternate Tuning includes the five following functions.
• TUNING
• BEND
• 12-STRING
• DETUNE
• HARMONY
You can use all of these functions simultaneously, in any
combination.
TUNING
This shifts the tuning of each string in semitone increments.
With the guitar left with the standard tuning (EADGBE), you
can convert the tuning to an open tuning such as OPEN-D or
OPEN-G, raise or lower all of the strings an octave, and achieve
various other tunings, all without changing the guitar’s actual
tuning.
When the type set in TUNING is something other than a preset
tuning, you can also create your own tunings as you like for
each individual patch with the USER tunings.
Using the TUNING function allows you to change tunings
instantly during songs, without having to change instruments,
and perform using tunings that are easier to play in, without
changing the string tension.
BEND
You can produce a pitch bend effect on any individual string or
combination of strings.
This features lets you make separate settings for the amount of
bend for each individual string, just as with a string bender or
pedal steel guitar. This is mainly used with Control Assign.
12-STRING
This changes the sound of a regular six-string guitar to that of a
twelve-string guitar featuring secondary strings. For each
individual string, you can set the shift in pitch for the secondary
string relative to the respective main string, the amount of
delay, and the volume.
DETUNE
This allows you to subtly shift the pitch of each individual
string.
When playing sounds from both COSM GUITAR [A] and [B],
switching DETUNE to ON in one of the channels to slightly
alter the pitch produces an effect resembling double tracking,
creating a sound with greater breadth and depth.
HARMONY
This analyzes the pitch of each string and adjusts the amount of
shift in the pitch to convert the pitches into harmonies matched
to the key. You can create and use the harmonies you like in
each individual patch with the USER TYPE function.
* With the GR-300 selected as the COSM guitar, expression of sounds
may become unstable when the Alternate Tuning 12STR is set to ON
or when pitches are shifted excessively.

Range
Explanation
AB LINK
OFF, ON This setting switches the AB LINK on and off.
When AB LINK is on, you can use the same
settings for the functions below on both
COSM GUITAR [A] and COSM GUITAR [B].
• TUNING
• BEND
When set to OFF, you can use set COSM
GUITAR [A] differently than COSM GUI-
TAR [B].
Unless you particularly want to change
the TUNING or BEND settings for
COSM GUITAR [A] and COSM
GUITAR [B], leaving AB LINK set to
ON is normally more convenient.
A/B
A, B This selects the channel used in setting Al-
ternate Tuning.
* You cannot set this when AB LINK is on.
TUNING
SW
OFF, ON This setting switches TUNING function on
and off.
TYPE
You can create and use your own original harmonies in each individ-
ual patch with the USER TYPE function.
OPEN-D This tuning produces a D chord when the
strings are played open.
OPEN-E This tuning produces an E chord when the
strings are played open.
OPEN-G This tuning produces a G chord when the
strings are played open.
OPEN-A This tuning produces an A chord when the
strings are played open.
DROP-D This tuning drops the note only on the 6th
string (D).
D-MODAL Also referred to as DADGAD, this tuning
drops the 6th, 2nd, and 1st strings one note,
lending the sounds an exotic air.
-1 STEP This tuning lowers the strings one semitone
(half-step).
All strings are lowered a semitone (corre-
sponding to one fret).
-2 STEP This tuning lowers the strings one whole
step.
All strings are lowered a whole step (corre-
sponding to two frets).
BARITONE This tuning lowers all strings a perfect
fourth (five frets), making it well suited for
heavy phrasing.
NASHVL With this tuning, the 6th, 5th, 4th, and 3rd
strings are raised an octave, just like having
only the secondary string for these string
pairs on a twelve-string guitar.
