MIDI CHANNEL SELECTION
1. Press both channel SELECT buttons (E and I) simultaneous-
ly to initiate MIDI "learning mode." The current amp channel
LED will start to flash.
2. Send any desired program change message on any desired
channel from a MIDI controller to the amp. The channel one
LED (green) will start to flash unless the program change
message has previously been assigned to a different amp
channel (in which case the LED for the previously assigned
channel will start to flash).
3. Select the target amp channel (one, two or three) using
the channel SELECT buttons (E and I). All three amp channel
LEDs will briefly illuminate to indicate if the amp channel
assignment has been changed for the program change mes-
sage sent (if the amp channel assignment has not changed—
which would be the case when assigning amp channel one
to a program change message for the very first time—the
three amp channel LEDs will not all illuminate briefly,
because the amp channel assignment has not changed from
the default amp channel one assignment).
If the program change message is currently assigned to amp
channel one (default), the channel one/two select button (E)
must be pressed twice to select amp channel two. If the pro-
gram change message is currently assigned to amp channel
two, the channel one/two select button (E) must be pressed
twice to select amp channel one.
4. Repeat steps two and three for each channel on the amp,
if desired. For greater flexibility, multiple program change
messages can also be assigned to the same amp channel.
Note that the footswitch can be used to temporarily change
channels at any time during MIDI setup; this will have no

effect on saving amp channel assignments. All channel
assignment changes must be made using the front panel
channel select buttons (E and I).
5. When MIDI program change setup is complete, exit "learn-
ing mode" by pressing both front panel channel select
buttons (E and I) simultaneously. The amp is now set up to
switch to the target channels whenever the selected pro-
gram change messages are sent on the selected MIDI chan-
nel.
Note that the default MIDI channel for the amp is channel
one. The amp MIDI channel can be changed by sending a
program change message from any other desired MIDI chan-
nel while in "learning mode." The amp will then respond only
to program change messages and control change messages
on that new MIDI channel.
MIDI USE FOR EFFECTS LOOP BYPASS
No setup is required. From MIDI channel one (default) or the
channel used to send program change messages in the sec-
tion above (if different from MIDI channel one), simply send
a control change #85 message with a value of 63 or less to
bypass the effects loop, or a value of 64 or greater to enable
the effects loop.
