User Data Dump (Backup)
A User Data Dump will send a User Data Dump file with the MIDI Matrix™ Amp Controller 250 presets and all its configuration set-
tings out through the MIDI Thru/Out jack, as a MIDI SysEx message. The User Data Dump file includes CRC (Cyclic Redundancy
Check) bytes for MIDI error detection.
To perform a User Data Dump from one MIDI Matrix™ Amp Controller, to another MIDI Matrix™ Amp Controller, making an exact
clone, connect the MIDI Thru/Out jack of the original, to the MIDI In jack of the clone. Remember to set the MIDI Channel of the clone
so it matches that of the original MIDI Matrix™ Amp Controller (unless you don’t actually want them to respond to MIDI messages
on the same MIDI channel).
The User Data Dump file can also be saved to a computer, as a backup or to load the data into another MIDI Matrix™ Amp Controller,
at some other time. In addition to the computer, you will also need a MIDI/USB Interface, and a MIDI app/utility capable of sending
and receiving MIDI SysEx messages and files. Two free apps that we recommend are SysEx Librarian by www.snoize.com (Mac OS
X) and MIDI-OX by www.midiox.com (Microsoft Windows).
A User Data Dump can be performed after;
• The MIDI Matrix™ Amp Controller is first powered-up, and prior to receiving any MIDI messages.
• The MIDI Matrix™ Amp Controller has received a User Data Load file, whether successful or not.
Perform a User Data Dump in four easy steps;
1. Connect the MIDI Matrix™ Amp Controller MIDI Thru/Out jack to either the MIDI In of another MIDI Matrix™ Amp Controller or
that of a MIDI/USB Interface, in which case launch the MIDI app/utility you plan to use, and make sure the Interface is connected
to the computer.
2. If dumping to a computer, set the MIDI app/utility to receive, then press the MIDI Matrix™ Amp Controller’s Store button to begin
sending the User Data Dump file.
3. The MIDI Matrix™ Amp Controller Store LED will turn on immediately, and after the User Data Dump file has been sent, the
Store LED will turn off.
4. The Store LED will then turn on again, when a second, very short MIDI SysEx message containing the MIDI Matrix™ Amp
Controller software version information is sent.
A User Data Dump should take no more than 1 to 2 seconds to complete.
NOTE: The Software Version SysEx message that follows every User Data Dump file, providing a simple means of identification, can
be ignored, unless it’s needed for troubleshooting a particular problem.
User Data Load (Restore)
A User Data Load can be performed at any time and can be received at full MIDI speeds. When receiving a User Data Dump file,
it is first saved in the MIDI Matrix™ Amp Controller RAM memory, and does NOT immediately overwrite the existing presets and
configuration settings that are saved in the User Data EEPROM Memory. The existing presets and configuration settings will ONLY
be overwritten after the entire User Data Dump file has been completely and successfully received without CRC errors.
Perform a User Data Load in four easy steps;
1. Connect the MIDI Matrix™ Amp Controller MIDI In jack to either the MIDI Thru/Out of another MIDI Matrix™ Amp Controller or
that of a MIDI/USB Interface, in which case launch the MIDI app/utility you plan to use, and make sure the Interface is connected
to the computer.
