MESA FOOTSWITCH & MIDI IMPLEMENTATION
MESA FTSW
This 7-Pin DIN jack accepts the MARK VII Footswitch cable or any other standard 7-Pin DIN style cable, should
you misplace the included cable. The MARK VII Footswitch allows direct access to the three Channels, Eects
Loop, Graphic EQ and Reverb. It comes in very handy for those players who don’t use MIDI to control their
stage or studio set up and also provides easy demonstration of the features and sounds of the MARK VII in
dealership environments.
NOTE: Do not connect any MIDI devices to the MIDI INPUT jack when using the MESA FTSW jack!!
To use the MARK VII Footswitch, connect the 7-Pin DIN cable to the MESA FTSW jack on the Rear Panel, mak-
ing sure to line the pins up correctly. Do NOT force the cable into the jack! When the pins are aligned, it will fit
easily, though snugly, into the jack.
Connect the other end of the 7-Pin DIN cable to the similar jack on the MARK VII Footswitch; the STORE LED
and all of the Footswitch LEDs should turn on briefly, then at least one Footswitch LED should remain on. If not,
unplug the cable and try connecting it again, making sure the pins are properly aligned. Check the MARK VII
Footswitch connection as well to be sure the cable is seated all the way home there also. When a button on
the Footswitch is pressed, the STORE LED will flash once, indicating a button has been pressed.
NOTE: Do not use the MARK VII Footswitch and a MIDI foot controller at the same time. Choose one or the other to control
your amplifier, and DO NOT CONNECT THE JACK that corresponds to the switching method YOU DO NOT INTEND TO USE.
BUILTIN CABLE CHECK FEATURE:
The Footswitch has a built-in cable check feature which is activated when the MIDI CHANNEL SELECT SWITCH
is set to Channel #1 (position ‘0’). So, if the Footswitch cable is damaged at any time, or there’s a communica-
tions failure with the MARK VII, all of the Footswitch LEDs will blink steadily, assuming it is still receiving power
from the MARK VII, of course.
CONTROLLING MULTIPLE MARK VIIS:
Controlling multiple MARK VIIs with one Footswitch is easily accomplished by connecting the Footswitch to
the MESA FTSW jack on one MARK VII and connecting the MIDI THRU/OUT from this MARK VII to the MIDI
INPUT on a second MARK VII. For a third MARK VII, connect the MIDI THRU/OUT from the second MARK VII to
the MIDI INPUT on the third MARK VII, and so on.
When controlling multiple MARK VIIs, only the MARK VII with the Footswitch connected to it should be set to
MIDI Channel #1; all of the other MARK VIIs should be set to another (any) MIDI Channel. Additionally, the Front
and any rear panel toggle and/or rotary switches should be set to their center / o / FTSW position (for no other
reason than to minimize any confusion).
EMERGENCY FAILSAFE FOR A LOST FTSW CABLE:
If the supplied 7-pin DIN Footswitch cable is lost, a temporary (for emergencies only) solution is to use a stan-
dard MIDI cable, which must have all 5-pins connected as per the MIDI specification. The Footswitch LEDs will
blink five times when it is first connected to the MARK VII, indicating there’s a cable issue, and the LEDs will
remain o, but the buttons will still operate normally, allowing the Channels and other on/o functions to be
selected.
