"Lt.A" (Latch hold type A)
With an ordinary hold function, pressing the pedal
starts the hold, and releasing the pedal ends it.
With a latch hold, however, pressing the pedal
once starts the hold, and pressing the pedal again
ends it. On the GR-30, a latch hold is available
only when using Arpeggiator.
When "Lt.A" (Latch hold type A) has been chosen
and Arpeggiator is sounded, pressing pedal 3
(HOLD) makes the GR-30 hold the arpeggio being
played at the moment when the pedal was
pressed. This is a latch hold, so the effect contin-
ues even if you release the pedal. The effect ends
when you press the pedal again. As with "SoS,"
nothing you play on a new string is reflected in the
effect.
During the latch hold, you can use pedal 4 "CTRL
ARP/HAR" (which normally toggles arpeggios on
and off) to perform chord changes for the arpeg-
gios without disrupting the rhythm.
<An Example of Using Hold Set to "Lt.A">
1. Choose patch H82 ("Lt.A" is used as the hold
type).
2. Go into the Pedal Effect mode and strum a suitable
chord. This starts the arpeggios (nylon-string gui-
tar accompaniment).
3. While Arpeggiator is playing the nylon-string gui-
tar accompaniment, press pedal 3 (HOLD).
4. The arpeggio (accompaniment) being played at the
moment the pedal was pressed is held, and contin-
ues to be held even if pedal 3 is released.
5. Nothing played on the strings during hold has any
effect on Arpeggiator, so you can play a melody
along with the accompaniment.
6. If you want to do a chord change, press pedal 4
(CTRL ARP/HAR) and play the new chord, then
release the pedal. The chord changes without
stopping the rhythm of the arpeggios being
played.
7. To stop the arpeggios, press pedal 3 (HOLD)
again.
Every time you press pedal 4, the unit instantly deter-
mines the string for the lowest note (the chord's root)
and restructures the arpeggios.

"Lt.B" (Latch hold type B)
Basic operation is the same as for "Lt.A" — the
hold is maintained even if you take your foot off
the pedal, and the hold is released when you press
the pedal again. "Lt.B" is also like "Lt.A" in that
nothing you play while the hold is in progress
affects the arpeggios.
The difference with "Lt.A" lies in the behavior
when the guitar is played while pedal 4 (CTRL
ARP/HAR) is depressed.
With "Lt.B," the arpeggios produced by this action
are the same as for "dPr." There is no restructur-
ing of the arpeggios themselves based on the selec-
tion and number of strings played, as with "Lt.A."
<Hearing the Difference Between "Lt.A" and
"Lt.B">
1. With patch H82, play a suitable chord with all
strings, and apply the latch hold (Lt.A) to the
arpeggios that are sounded.
2. Press pedal 4 (CTRL ARP/HAR), and while hold-
ing down the pedal, play just one or two strings on
the guitar. Listen to how the arpeggios change.
3. Follow the steps on p. 53 to change the hold type
to "Lt.B," then repeat steps 1 and 2 above. You
can hear how the changes in the arpeggios are dif-
ferent from "Lt.A."
