!! IMPORTANT !! MIDI app/utility settings for the Software Update:
SysEx Librarian (Mac OS X)
Menu > Preferences
Transmit Speed = 50% or 1565 bytes/sec max.
MIDI-OX (Microsoft Windows)
Main Menu > View > SysEx
SysEx Window Menu > SysEx > Configure

Output Timing & Delay Between Buffers = 192ms min.
Auto-Adjust Buffer Delays If Necessary = Off/Unchecked
As with any piece of gear, it’s always a good idea to backup your presets and other settings before performing a Software Update.
Perform a Software Update as follows:
1. Press and hold both the Store button and Switching Function #8 button, while applying power to the MIDI Matrix™ Amp Controller.
2. When the Store and the Switching Function #8 LEDs turn on, release both buttons. The Switching Function #8 LED will turn off,
but the Store LED will remain on, indicating the Software Update mode.
3. Connect the MIDI/USB Interface to your computer, launch the MIDI app/utility you plan to use, and then connect the Interface’s
MIDI Output to the MIDI Matrix™ Amp Controller MIDI In jack.
4. Locate the Software Update file you received from us, or downloaded, and verify its checksum is correct (as follows) before
proceeding to Step #5.
SysEx Librarian includes two different methods of calculating a file’s checksum. You should check one or both of these against
the checksums we’ve published to ensure the file you have, is not corrupted.
Unfortunately MIDI-OX doesn’t provide a built-in checksum feature, but Microsoft does offer a free utility called “Microsoft File
Checksum Integrity Verifier” which does the same thing. Download it from www.microsoft.com .
5. Begin sending the Software Update file. Upon receiving it, the Store LED will begin to blink on and off quickly, and will continue
to blink during file reception, providing an indication that the Software Update is progressing problem free.
6. After performing a successful Software Update, the Store LED will stop blinking and turn off, and on again, as the MIDI Matrix™
Amp Controller is automatically restarted.
A Software Update should take no more than 20 to 30 seconds to complete.
If a Software Update fails, the Store LED will stop blinking and remain on until the MIDI Matrix™ Amp Controller begins receiving
another Software Update file. Any failures could only be due to either a corrupted file or because the file is being sent to the MIDI
Matrix™ Amp Controller faster than it can be processed. So, if a Software Update failure occurs, stop the file transfer, and check the
MIDI app/utility data transmission/speed settings.
• If the settings are not as shown above, correct them, then press Switching Function #1 button (this resets the MIDI Matrix™ Amp
Controller Software Update process) before attempting to send another Software Update file.
• If the settings are correct, then chances are the Software Update failure was due to a file corruption error. Retry sending the
Software Update file. If the Store LED doesn’t begin to blink on and off quickly, press Switching Function #1 button, to reset the
Software Update process, and try re-sending the Software Update file.
NOTE: To abort a Software Update before sending a Software Update file (in Step #5), simply remove power. The MIDI Matrix™ Amp
