MIDI Channel Switching
The Series One offers the ability to control channel selection via MIDI Program
Change messages and interfacing with most MIDI controllers is a straight forward
process. The Series One can be placed in a MIDI chain allowing you to
simultaneously select a channel on the amplifier and change the patch on a MIDI
effects processor connected to the effects loop. There are 128 available Program
Changes, giving you the possibility to access a vast number of tonal combinations.
To set-up MIDI channel switching, simply connect the MIDI controller's MIDI Out
socket to the MIDI In socket on the rear of the amplifier. The controller should be set
to transmit Program Change messages (this is usually the case). From new, a Series
One amplifier is set to OMNI mode and responds to Program Change messages on
all MIDI channels. Changing 'patches' on the controller will change the selected
channel on the amp. The default settings for each Program Change number are
shown in the table below:

Program Change Assignment
To change the default assignments and set the amp up to respond to a different set
of Program Changes:
1. The amp must be powered on with either the Standby switch set to on, a jack
in the Input socket, or both.
2. Send the appropriate Program Change message to the amp.
3. Press and hold in the appropriate front panel Channel Select switch for
2 seconds.
The corresponding channel will be selected and its LED will flash three times in quick
succession to indicate it has been assigned to the last received Program Change.
The amplifier will now remember the selection. Repeat the operation until all your
Program Changes have the desired amp channel assigned to them.
MIDI Receive Channel Selection
As mentioned previously, the default mode is set to OMNI and the amplifier will
respond to MIDI Program Changes on all MIDI channels. You may wish to set the
amplifier to respond to Program Changes on just a single MIDI channel. The Series
One can be set to respond in this way for any of the first seven MIDI channels as
follows:
1. The unit must be in standby (Power (34) on and Standby (33) off), and no lead
connected to the Input jack.
2. Simultaneously press and hold the Clean (3) and OD1 (17) Select switches.
3. After 2 seconds the LED for OD2 (20) will begin to flash continuously (2 flashes
per second) to indicate that the unit is in MIDI Receive Channel Program Mode.
4. Release the Clean (3) and OD1 (17) Select switches and select the required MIDI
channel by using the Channel Select switches as shown in the table below:
Clean

The corresponding Channel Select LEDs will illuminate to show the selection and
each press of the Channel Select switches will toggle the state of its associated
LED.
5. To store the desired selection press the OD2 (21) Select switch. The OD2 (20)
Select LED will flash quickly four times when the operation is complete. The unit
will then revert to normal operation, and will respond only to Program Changes
on the newly selected MIDI Channel.
