Midi Operation - Marshall JVM2 Serie Manual De Instrucciones

To store the current status simply:
Set the amplifier to FOOTSWITCH PROGRAM
mode (red light ON).
Press and hold the desired switch for about 3
seconds.
The FX footswitch LED will flicker a couple of
times indicating that the preset has been stored.
In switch store mode, any of the footswitches
can be configured to replicate the front panel
switches and the amplifier will react exactly in
the same way as when you operate them on the
front panel.
All the front panel switches can be mapped to
any of the footswitches without any limitation.
The only exception is the FOOTSWITCH / MIDI
PROGRAM switch which cannot be assigned to
the footswitch.
To assign any of the front panel switches
(except FOOTSWITCH / MIDI PROGRAM) to
any of the footswitches simply:
Set the amplifier to FOOTSWITCH PROGRAM
mode (red light ON).
Press and hold the desired footswitch.
While holding the footswitch down, in less than
3 seconds, press the front panel switch you
want to map.
The FX footswitch LED will flicker a couple of
times indicating that the switch has been
mapped.
From now on the selected footswitch will act
exactly in the same way as if you press the
related front panel switch.
Switches and presets can be assigned as
wished without limitation and in any order
(again, except the FOOTSWITCH / MIDI
PROGRAM switch). The footswitch configuration
is stored in the footswitch itself, not in the
amplifier. Resetting the amplifier will not affect
the footswitch configuration as well.
The footswitch can be hot-swapped and
synchronises itself with the amplifier after
connection. However it is recommended to
connect the footswitch lead to the footswitch
side first and then connect it to the amplifier.

MIDI operation

Pressing the FOOTSWITCH / MIDI PROGRAM
switch (3) twice puts the amplifier in MIDI
waiting mode, the LED will flash until a valid
MIDI program change command is received.
On reception of a MIDI program change
command the amplifier stores the current status
(Channel + FX + Reverb + Master Settings) in
the MIDI program number received. It is
possible to store up to 128 different MIDI
presets.
To exit this status without waiting for incoming
MIDI data press the FOOTSWITCH / MIDI
PROGRAM switch (3) again.
Note about MIDI channels: By default the
amplifier is configured to listen to MIDI channel
#1 but it can be changed to listen to any of the
16 MIDI channels as follows:
Switch the amplifier off (Power switch (1), not
Standby (2)).
Press and hold the FOOTSWITCH / MIDI
PROGRAM switch (3).
Switch the amplifier on (Power switch (1)).
Release the FOOTSWITCH / MIDI PROGRAM
switch (3), the LED will start to flash.
Send ANY MIDI command using your MIDI
pedalboard or any other MIDI equipment.
The amplifier will detect which channel came in
and configure itself to listen to that MIDI channel
only. From now on any MIDI preset you had
previously stored will be activated only on the
new channel regardless of what channel you
used before, this allows a fast reconfiguration
should there be a MIDI conflict with any other
outboard equipment.
If you want to exit the MIDI channel selection
without any action press the
FOOTSWITCH / MIDI PROGRAM switch (3)
while waiting for MIDI data.
