selecting the preset (preset numbers will be displayed as flashing until selected). When
the desired preset number is displayed, it can be selected and loaded by pressing the 
middle EDIT switch.

In Split Mode, the middle LED strip is used exclusively to indicate the current status of 
the instant access switches on the bottom row. Only the 

red

 LEDs are used. The yellow 

control switch LEDs are not used in Split Mode (the control switches are still updated 
with the presets, though).

Direct Mode

Direct Mode provides direct instant access to the pedal loop, switch states, and MIDI 
continuous controller or note switches (if enabled in setup). To enter Direct Mode from 
Preset Mode, press the EDIT  switch. This button is used to toggle back and forth 
between Preset Mode and Direct Mode, providing the flexibility to quickly make 
spontaneous changes. 

Direct Mode is arranged by function. There are up to four available instant access 
“pages”, depending on what functions have been enabled in SETUP. Direct mode 
pages function as follows: 

LPS 

is a dedicated page for the bypass loops. Pedal bypass loops are toggled on and 

off using the bottom row switches 4, 3, 2, 1. The 

red

 LEDs above each switch indicate 

the state of the loops.

 

FnS 

is used for the control function switches (SW1 and SW2). The bottom row 

switches 1&2 control SW1, and switches 3&4 control SW2 

(Both switches nearest to 

each indicator LEDs are able to be used to control the switches – use either).

The 

green status LEDs are located above the footswitches.

CC

.

A

 or 

NT

.

A

(only available if activated in SETUP MODE) is used for instant access 

control of the CC.A MIDI Control or NT.A MIDI Note switches. The 

red

 LEDs above each 

switch indicate the state of the controllers.

CC

.

B

 or 

NT

.

(only available if activated in SETUP MODE) is used for instant access 

control of the CC.B MIDI Control or NT.B MIDI Note switches. The 

red

 LEDs above each 

switch indicate the state of the controllers.

As you toggle back and forth between Preset Mode and Direct mode, the instant 
access page will stay where you leave it. This is useful if there is one page that you 
want to access most. For example, if you are using Direct Mode to mainly control your 
pedal loops, then you can simple leave the page set to 

LPS

. If you mostly use Direct 

Mode for switching amp channels, then you can select the  

FnS

 page and it will always

be what you see first when entering Direct Mode.
