5. To store the desired selection press the Super Crunch (11) Select switch. The
Super Crunch Select LED (10) will flash quickly four times when the operation
is complete. The unit will then revert to normal operation, and will respond only
to Program Changes on the newly selected MIDI Channel.
MIDI Dump Out
You may wish to back up the MIDI channel select settings so you can transfer
them to another amplifier, for example. To do this you will need a MIDI Sysex
librarian, which is usually a piece of software running on a PC or MAC with a
suitable MIDI interface.
1. The unit must be in standby (Power (24) on and Standby (23) off), with no
lead connected to the Input jack and the MIDI Thru on the rear of the amplifier
connected to the MIDI In of the MIDI interface.
2. Simultaneously press and hold the Warm Clean (5) and Super Crunch (11)
Select switches. After 2 seconds the LED for Crunch (8) will flash continuously
to indicate that the unit is in MIDI Dump Mode.
3. Prepare the receiving equipment for the transfer. For example, if using a MIDI
Sysex librarian this must be put into file receive mode.
4. Start the file transfer by pressing and quickly releasing the Crunch (9) Select
switch. During the file transfer the Crunch Select LED (8) will flash quickly.
When the flashing stops the transfer operation is complete and the amplifier
will revert to normal operation. The file should be saved as a MIDI System
Exclusive file.
MIDI Dump In
To load in previously saved Program Change assignments:
1. Connect the MIDI Out of the MIDI recording device to the MIDI In on the rear of
the amplifier and use the MIDI Sysex librarian to send the previously stored
MIDI System Exclusive file.
The amplifier overwrites the current Program Change assignments with the new
ones. If the operation completes successfully all four channel LEDs flash quickly
four times. If the dump is unsuccessful or incomplete the four LEDs will flash
slowly in an alternating pattern and then the unit will revert to normal operation.
Note: During reception of the System Exclusive file the amplifier will temporarily
cease to pass data to the MIDI Thru socket.

Restoring Factory Settings
To return the amplifier to its factory default state:
1. With the amplifier Power off, press and hold in the Warm Clean (5) and Super
Crunch (11) Select switches.
2. While holding in the switches turn on the amplifier. After 2 seconds all channel
select LEDs flash once to confirm the factory defaults have been restored.

Any MIDI data received at the MIDI In socket is passed out of the MIDI Thru socket
so that other MIDI devices can be placed in a chain. The MIDI Thru socket also
serves as a way of dumping Channel Select/Program Change data to a suitable
MIDI storage device. Refer to the MIDI Channel Switching section for more details.
Always use a good quality MIDI lead.
