Chapter 6 Appendices
When Using the GR-20 with
other MIDI devices
●
The external sound module connected to the MIDI OUT
connector does not sound
◆
Do the MIDI channels of the transmitting and receiving
devices match?
→
Match the MIDI channels (p. 29).
◆
Could you have turned down the volume using the
volume control of the GK pickup or the expression pedal?
→
Raise the controller or volume.
●
Only one string sounds on the external sound module
(some strings do not sound)
◆
Could you be using Mono mode to transmit from the GR-
20 to a sound module that is unable to receive six MIDI
channels simultaneously?
→
Use a sound module that supports multitimbral
operation (p. 28).
→
Use the GR-20 in Poly mode.
●
Pitch is incorrect (different than the guitar pitch)
◆
Is the Bend Range of your external sound module set to
+-24?
→
Set the Bend Range of your external sound module to +-
24.
◆
Is your guitar tuned accurately?
→
Use the GR-20's Tuner function to tune your guitar
accurately. You must also adjust your guitar so that
accurate pitches are sounded even on the high frets.
●
Pitch does not change smoothly
◆
On the GR-20, could you have selected a patch such as
piano or organ for which the pitch changes in semitone
steps?
→
Select a patch on the GR-20 whose pitch will change
smoothly.
●
When you view the note messages recorded in your
sequencer, the pitches differ from what is actually
sounded
◆
In order to convey the beginning of a note as quickly as
possible, and to allow the pitch to change flexibly, the
GR-20 transmits the pitch as a combination of note
messages and pitch bend messages. This means that
when you view only the note data using the event list
(“microscope”) screen of your sequencer, the data may
appear to be different than the pitch that is actually
sounded.
Other
●
The volume level of the instrument connected to MIX
IN jack is too low.
◆
Could you be using a connection cable that contains a
resistor?
→
Use a connection cable that does not contain a resistor.
