To Send Only Bank Program Change
Information
To set up the GFX-8 so that it sends bank select infor
program change information corresponding to a patch, proceed as
follows. This is useful for example to switch programs at a MIDI
compatible amplifier or effect device when a patch is switched at the
GFX-8.
1.
In play mode or edit mode, press the MIDI key.
The MIDI key lights up, and the unit enters the MIDI utility
mode.
2.
Turn the PARM SELECT knob so that the
GROUP/BANK indicator shows "04".
The display shows "PCOUT ON" or "PCOUT OF".
3.
If required, turn the PARM VALUE knob so that the
display shows "PCOUT ON", then press the EDIT key.
The program change output is now enabled, and the GFX-8
returns to the play mode.
4.
Switch a patch at the GFX-8. The bank select MSB,
bank select LSB, and program change corresponding
to that bank is output.
For information on the relationship between GFX-8 patches
and bank select MSB/bank select LSB/program number, see
the table on page 36.
To Send Control Change Information
Besides pedal and foot switch operation, the GFX-8 can be set up so
that it sends two types of control change information (called CT1 and
CT2) immediately after sending bank program change
information when a patch is changed. The control number and
value of CT1 and CT2 can be defined freely and stored separately for
each patch. For example, this is useful to control the volume setting at
a MIDI compatible amplifier or synthesizer.
1.
In play mode or edit mode, press the MIDI key.
The MIDI key lights up, and the unit enters the MIDI utility
mode.
2.
Turn the PARM SELECT knob so that the
GROUP/BANK indicator shows "05".
The display shows "CTOUT ON" or "CTOUT OF".
3.
If required, turn the PARM VALUE knob so that the
display shows "CTOUT ON", then press the EDIT key .
The control change output is now enabled, and the GFX-8
returns to the play mode.
This setting affects all control change output operations of
the GFX-8.
4.
Press the TOTAL key twice, so that the LED flashes
green.
Page 2 of the TOTAL module can now be edited.

6.
Turn the PARM VALUE knob to select the group, bank
number, and patch number to assign to the currently
shown program number.
You can use the BANK UP/DOWN foot switch and foot
switches 1 - 4 to specify the respective group, bank number, and
patch number.
7.
Repeat steps 5 and 6 until all desired program
numbers have been mapped to their respective
patches.
If desired, you can also assign several program numbers to the
same patch.
8.
When the entire assignment process is completed,
press the EDIT key.
The program change map is stored, and the unit returns to the
play mode.
9.
Send a program change message from the external
MIDI device.
The patch assigned to the program number will be called up.
• When using the program change map, there is no need
to send bank select information from the external MIDI
device.
•
The program change map is active only for receiving
MIDI messages. The program number information sent
by the GFX-8 when patches are switched is fixed (see
page 36).
When you switch a patch with the controls on the top panel of the GFX-8, the unit can send program change information and
control change information to an external MIDI device. To do this, connect the MIDI OUT connector of the GFX-8 to the MIDI IN
jack of the external MIDI device, using a MIDI cable. Set the MIDI send channel at the GFX-8 and the MIDI receive channel (RXCH)
at the external MIDI device to the same settings.
This function of the GFX-8 can be set up in two ways, as follows:
GFX-8 sends only bank select infor program change information when the patch is switched GFX-8 sends bank select
infor program change information followed by two types of control change information (CT1 + CT2).
