MIDI control
Program change and control change messages can be sent
from the MIDI OUT connector of the 4040, according to
pedal operation and pedal switch on/off operation. This lets
you control equipment with a MIDI IN connector from the
4040. For example, you can change the program of a guitar
synthesizer when selecting patches at the 4040, or call up
settings at a MIDI-equipped preamplifier such as the ZOOM
9150.

Sending control change messages
When the VOL pedal or EXP pedal is operated, special
control change messages with continuously varying values
are sent from the MIDI OUT connector.
If the 4040 is in the Manual (Edit) mode, special control
change messages are sent when a module is switched on and
off via the pedal switches. In this case, the output has only
two values (on = 127, off = 0). Likewise, when the 4040 is

MIDI channel selection
When wishing to use the MIDI OUT connector of the 4040
to control external equipment, the MIDI channel of the 4040
must be set to match the equipment. This is done be setting
the TOTAL parameter MIDI CH.
• In Play mode, press the EDIT/CANCEL key to
activate the Edit mode.
• Use the PARAMETER SELECT key to select the
TOTAL parameter MIDI CH.
• Use the VALUE +/- keys to set the value (MIDI
channel 1 - 16).
Swapping the pedal functions
The pedals of the 4040 are normally set up so that the left
pedal operates as volume pedal and the right pedal as
expression pedal. If desired, the function of the pedals can
be interchanged as follows.
• Turn off the 4040 (with the amplifier volume set to
minimum), and turn the unit back on while keeping
the GROUP key depressed.
The indication "VE" flashes on the display. In this
condition, the left pedal operates as volume pedal and the
right pedal as expression pedal (factory default).
• Use the VALUE +/- keys to change the value.
When "EV" is shown, the right pedal operates as volume
pedal and the left pedal as expression pedal.
• Press the STORE key.
The new setting is stored, and the unit switches to Play
mode. If you wish to cancel the function, press the
EDIT/CANCEL key instead of the STORE key.
