If you have access to a data filer, sequencer or
other external MIDI storage device you may wish to
down load the programmed data from your JFX-1
using the System Exclusive Back-up. You could also
use the ‘Back-up’ function to transfer data between
two JFX-1 units.
You would need to connect a standard MIDI
cable from the MIDI OUT of the JFX-1 to the MIDI
IN of the receiving device.
Press the ‘System’ key to get into the System
menu.
Use the ‘Up’ key to move the cursor until it

To reload the stored information from an external
MIDI device you should connect the MIDI OUT of
the transmitting device to the MIDI IN of the JFX-1.
Press the ‘System’ key to get into the System
menu.
Use the ‘Up’ key to move the cursor until it
rests under MIDI.
Use the ‘System’ key to scroll through the other

precaution to ensure that the system is returned to the
DISABLED mode after information has been down
loaded
WARNING :
Receiving a MIDI dump will re-
write all your existing program and mapping data - if
you are unsure that the data you are loading is
correct make a back-up of your current data before
re-loading. The JFX-1 will only receive a data re-
load with the System Exclusive ENABLED.
When you start re-loading, the JFX-1 will
automatically default to the System Exclusive in
progress display.
The Display shows:
The three digits will automatically progress in
sequence up to ‘111’ until the re-load is complete.
The Display shows:
If there is an error in the MIDI data, The JFX-1
will abandon the load.
The Display shows:
In this instance you could try the re-load again,
the error could be due to a file corruption or a faulty
cable.

12. 5 - MIDI Controllers
For live performance it can be beneficial to be
able to adjust certain program parameters remotely
via a pitch wheel or expression pedal.
Each of the 127 programs in the JFX-1 can have
up to four parameters assigned for continuous
control. Each effects mode features a selection of
assignable parameters from which you can choose
the most useful for your needs (see 12.6 for listing of
MIDI controller parameters available for each mode).
To program the MIDI controllers you
must first enter the system menu by pressing
the ‘System’ key.
Use the ‘Up’ key to move the cursor
until it rest under MIDI.
Press the ‘System’ key four times to take
you through the MIDI channel, Input
mapping and Output mapping selections.
The Display shows:
Use the ‘Up’ and ‘Down’ keys to select
the internal number of the parameter to be
controlled (1 -4).
Use the Data Control ❷ to select the
external MIDI controller number (off and
000 - 121).
Note : The JFX-1 leaves the factory with all the
MIDI control numbers in the ‘Off’ position.
Use Data Control ❸ to select the
individual parameter to be controlled.
Note : In certain effects modes there are
a greater number of parameters available
than the four allocated to each program. In
this case you should scroll through using
Data Control
❸
before making your
selection.
Finally you will need to store the selected MIDI
Controllers for the individual program by
pressing the ‘Store’ key.
The Display shows:
If you are happy with the location displayed press
‘Store’ again to complete the process.
