SOFTWARE VERSION I.D. MESSAGE

A very short MIDI SysEx message will follow every User Preset Dump ﬁle, as a simple means of identifying the

ampliﬁer’s Software Version. This MIDI SysEx message is ignored when a User Preset Load is being received.

To view this MIDI SysEx message, you will need a computer, a MIDI/USB Interface, and a MIDI app/utility ca-

pable of sending and receiving MIDI SysEx messages or 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). To capture

and view this message on a computer, simply select “Record Many” or “Receive Many” as an option within the

MIDI app/utility being used, before performing a User Presets Dump.

The Software Version I.D. Message will look like: F0 00 01 4B 0A 68 x y F7

Where x y is the actual Software Version, for example, 1.1 would be shown as: 01 01

MIDI SOFTWARE UPDATES

NOTE: Software Updates should be performed with the ampliﬁer in STANDBY and the MIDI THRU/OUT and MESA FTSW

jacks left unconnected.

To perform a Software Update, you’ll need a Software Update ﬁle (which can be obtained from us via e-mail

or the web), a computer, a MIDI/USB Interface, and a MIDI app/utility capable of sending and receiving MIDI

SysEx messages or 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).

As with any piece of gear, it’s always a good idea to back up your presets and other settings before performing

a Software Update.

PERFORM A SOFTWARE UPDATE AS FOLLOWS:

1. With the MARK 7 turned o, set the REVERB SWITCH to the on position, and all three CHANNEL EQ

switches to the o position, engage and hold the STORE SWITCH while powering up the ampliﬁer.

2. Release the STORE SWITCH after the ampliﬁer is turned on. 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 ampliﬁer’s MIDI INPUT 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 dierent methods of calculating a ﬁle’s checksum. You should check
