Chapter 9 Connecting to External Sound Generators and Sequencers
Chap.
9
* For a detailed explanation of Mono mode and Poly mode, see the
subsequent section, “Transmitting in Mono Mode or Poly Mode.”
* When using the GR-33 in combination with a multitimbral
sound module (a sound generator offering a number of
performance parts) or a sequencer system (an automatic
performance device), make sure the other instrument parts and
channels do not overlap.
❍ BEND RANGE
The GR-33 can even send continuous pitch changes obtained
with techniques such as bending, finger vibrators, tremolo
bar usage, and sliding to an external device. This is done
using MIDI Pitch Bend Change messages, just as with the
pitch bender on a keyboard. This means that the setting
called Bend Range must be matched up on the sending and
receiving instruments.
The GR-33 normally informs the external MIDI device of the
Bend Range setting on the GR-33, and sends a message
prompting change every time the patch is switched.
This means that the Bend Range value on the sound
generator can be set automatically every time the patch is
changed simply by matching the maximum Bend Range
value that can be set on the external MIDI sound generator to
the GR-33. (Setting Bend Range to as large a value as possible
will help enable smooth pitch changes in a wider range. The
settable range varies according to the receiving sound
generator. For equipment having a different settable width in
the bend up and down directions, match the setting to the
narrowest maximum value.)
About messages that notify the external MIDI
instrument of the Bend Range and prompt
change
The messages used here are MIDI RPN (Registered
Parameter Number) “Pitch Bend Sensitivity” messages
(Control Change messages No. 100, No. 101, No. 6, and No.
38). (Sending of these messages can be stopped, if necessary.
→ p. 98)
If you are using an external MIDI sound generator which
cannot recognize such messages, manually change Bend
Range on the external device to the same value on the GR-33.
Refer to the Owner’s Manuals for the external sound
generator for information about its MIDI specifications.
■ Setting the Channel (and Sending Mode)
and Bend Range
1. Press [SYSTEM] to enter System mode.
2. Press [PARAMETER] to select “BASIC CHANNEL.”
fig.9-02
3. Use [VALUE] to select the setting value.
BASIC CHANNEL can be set to values of “Mono 1–11”
(mono mode transmission) and “Poly 1–16” (poly mode
transmission).
* When transmitting in Mono mode, six consecutive channels
are used. For this reason, it is not possible to select 12--16 as
one of the first channels (BASIC CHANNEL).
4. When you finish making the setting for BASIC
CHANNEL, press [PARAMETER] to choose “BEND
RANGE.”
fig.9-03
5. Use [VALUE] to select the setting value.
BEND RANGE can be set to values of “0, 1, 2, 4, 5, 7, 12, 24.”
6. Maximum the setting to the maximum value for Bend
Range that can be set on the external sound generator,
then press [PLAY] to return to the Play mode.
* These are the setting items for the GR-33, and not patch
settings, so there is no need to perform a Patch Write
operation. The latest setting is automatically stored in
memory, even after the power is switched off.
If the sending Bend Range on the GR-33 is set to “0,” an effect
similar to setting COMMON “CHROMATIC” (p. 42) to
“Type3” is obtained for the sounds from the external MIDI
sound generator.
When a multitimbral sound generator has been connected
and Mono mode selected in step 3, the tones to be used are
allocated to six parts on the sound generator. Also, the
receiving channels are matched to the six connected channels
selected on the GR-33. When in this state, you can play the
external MIDI sound generator by playing the guitar own the
GK-2A is mounted.
* If not sound is produced by the external MIDI sound
generator, try turning the volume on the GK-2A all the up and
setting the GK-2A’s selector switch to “SYNTH” or “MIX.”
If there’s still no sound, check the sound-level settings on the
sound generator, as well as the cable connections. If the
setting “MIDI [PC]” described later (p. 88) has been changed,
make sure that it is set to any setting other than “Off.”
When Using the Volume Knob and Selector
Switch on the GK-2A
When the volume on the GK-2A is adjusted, the change is
sent by MIDI Control Change message No. 7 from MIDI OUT
on the GR-33. (The receiving instrument should be set to
recognize Control Change message No. 7.)
This makes it possible to control the volume level on the
external device with the volume knob on the GK-2A. Also,
when the selector switch on the GK-2A has been set to
