Note: The channel LED will flash blue when it turns OMNI mode ON, & RED when it turns OMNI 
mode off.  

 

MIDI Channel Setting  

 
This amplifier can either automatically or manually change the 16 MIDI channels you would like 
it to respond to. The channel change is stored in memory & only needs to be done when you 
need the amp to respond on a certain channel.  
 

1) In order to set the MIDI channel: With the power off, press & hold the Store button then 

turn on the power switch. The amp will power up & begin to flash 4 LEDs. Once this 
happens it is awaiting the channel data to be received from the external equipment 
(automatic) or to be set manually.  

 

2)

(Automatic, recommended)

 With your external equipment ready (pedals, computers, 

etc.) & set to the channel you want the amplifier to be controlled from via MIDI, send a 
command to the amplifier by pressing a program change button or CC command on your 
external equipment. Once the amplifier receives the data, it will verify the channel it 
received & save it to memory. Easy!  

 

3)

(Manual)

 Once step 1 has been completed above & the LEDs are flashing, press the 

channel push button. The channel LED will flash & the other LEDs will turn off, this 
signifies that MIDI channel 1 has been selected. Simply continue to press the channel 
push button to get to the channel you desire. As you press the switch you will notice the 
LEDs turn on as you increase the MIDI channel number. Once you reach the channel 
you desire, press the Store switch to save it to memory.  

 

MIDI Program Change  

 
This amplifier can remember up to 128 Program settings of the MIDI controllable functions. In 
order to set a program (i.e. amplifier configuration) to be controlled via MIDI:  
 

1) Set the amplifier to the configuration you intend to save to a program number. (Ex: Ch: 2, 

Aggression level: 2, Wide: ON)  

 

2) Once the amplifier is configured as you would like, press the Store push button. The 

Store LED will flash & the amplifier will wait now for a command through its MIDI IN jack.  

 

3) Send a Program Change command from your MIDI Pedal or other equipment with the 

correct channel & program number you intend to have the amplifier save the current 
configuration to.
