✽
It’s not possible to alter the correspondences between
Program Change numbers received by the GR-30 and
the GR-30 patches called up by these numbers. The At
the time of purchase, Program Change numbers 1
through 128 are assigned sequentially to patches A11
through d84, and this cannot be changed.
If you wish to make the sending numbers and the receiv-
ing numbers match up again, hold down pedal 2 and
switch on the power (causing “PG#” to appear on the
display), press [EDIT/PLAY], then press [+] and [-]
simultaneously (for details
→
p. 81).
When You Want to Have
Separate Sounds Programmed
for Different Strings
It’s possible to set different Program Change mes-
sages sent to an external sound generator not only for
each patch, but even for each string.
In steps 3 and 4 of the procedure just described,
“Changing the Program Change Number Sent to the
External Device During Patch Selection,” set the
STRING SELECT knob to any string-number position
other than “ALL” (such as 6-5, 6, 5, or the like), then
use [+] and [-] to make the change. This method
makes it possible to change the Program Change
number for just the string selected with the knob.
This also makes it simple to do unusual things like
assigning a different tone to each of the six strings
with the external sound generator. You can also mute
out certain strings for the external sound generator by
using the setting “oFF” (off) for the desired strings.
✽
You can make settings for different strings for an exter-
nal MIDI sound generator using the STRING SELECT
knob not only for Program Change messages, but for
sending MIDI Bank Select messages as well (see the
next section).
Selection of More Than 128
Tones (MIDI BANK SELECT)
Many recent MIDI sound generators offer more tones
than there are Program Change numbers (1 to 128).
These sound generators use MIDI Bank Select mes-
sages (Control Change No. 0 and No. 32) along with
Program Change messages when a tone is called up.
✽
The “bank” referred to here is an extended Program
Change message set forth in the MIDI specification, and
has absolutely nothing to do with the GR-30’s bank
number (the second place of the display that is, the
“Bank” in “Bank Shift,” “Bank Up, and “Bank Down”).
Care should be taken not to confuse the two.
Example 1
When calling up the “12-str.Gt” variation tone of
“Steel-str.Gt” with what is known as a GS-format
sound generator...
Send the value for Control Change No. 0 (“8”), then
send Program Change “26.”
Example 2
When calling up patch 014 “MKS-80 Brass” in Preset
Bank C on the Roland JV-2080, XP-80, or the like...
Send the value for Control Change No. 0 (“81” —
Preset) and the value for Control Change No. 32 (“2”
— C bank), then send Program Change “14.”
The GR-30 also supports this function for sending
Bank Select messages. This function is off at the time
of purchase, but can be switched on and used with
the following steps.
<Sending MIDI Bank Select Messages>
1. Choose the patch to be changed and press
[EDIT/PLAY] to enter the Edit mode.
2. Set the EDIT TARGET dial to “MIDI” and the
PARAMETER SELECT dial to “A” (PG CHNG#).
3. Press pedal 2. The display shows “b.SL” (Bank
Select), then the current state (“oFF”).
4. Press [+] to switch on the function.
✽
This selection (on or off) affects all patches, and is saved
automatically even when no patch write is performed.
5. Set the STRING SELECT dial to “ALL.”
6. Press pedal 3. The display shows “#.0” (Control
Change No. 0), then the current state. (At the time
of purchase, this is “0” for user patches.)
7. Use [+] and [-] to set the value for the tone to be
called up (from 0 to 127).
8. Press pedal 4. The display shows “#.32” (Control
Change No. 32), then the current state. (At the
time of purchase, this is “0” for user patches.)
9. Use [+] and [-] to set the value for the tone to be
called up (from 0 to 127).
10. Press pedal 1. The display shows “PrG.” (Program
Change), then the current Program Change num-
ber.
