Browsing Files for Playback 

When you first flip the switch to 

Playback

, the most recent recording in the most 

recent session folder will be selected as the current playback file. If there are no 

session folders on the card, then the folders will be scanned alphabetically and the 

first file in the first folder will be selected.

Hold down the button while turning the knob to browse the folder of the currently 

selected file. As soon as you start turning the knob with the button down, the lights 

will show you how many files are in the folder. Any light that’s turned on represents 

a file in the folder. For example, if six lights are on, then there are six files in the 

selected folder. The files are in alphabetical/numerical order.

The light corresponding to the currently selected file will be brighter than the others. As you turn the 

knob( while still holding the button down), the bright light will move through all the available files. See 

diagram below.

If you want to hear the new file that you've 

selected, you can play it like you would play any 

other file: just tap the button or fire a trigger into 

the jack. If you’re playing a long file, you can 

continue to browse while the file is playing without 

interrupting it. As long as you are holding the 

button down while turning the knob, the playback 

volume won’t change.

Folders with lots of files 

If there are more than eight files in a folder, then 

the files will be split up into “pages” of eight files 

each. The first and/or last light will flicker a bit to 

indicate there’s another “page” of files before or after it. The 

number of flickers indicates the next or previous “page” 

number (i.e, one flicker means you can access the 1st page 

by turning past that light, two flickers means the 2nd page 

is past that light, etc…) Turn the knob to the first or last 

light, and then keep turning it a little bit more to jump to the 

next or previous page. The light will jump from the first to 

last position, or vice-versa, when you change pages.

Browsing to a new folder

If you want to select a file in a different folder, 

press and hold the button while turning the knob 

just like you do for file selection. Turn the knob all 

the way up (to access the next folder) or all the 

way down (to access the previous folder), and 

leave it there for about two seconds (while still 

holding the button down). The four lights on the 

left or right column will flash rapidly to tell you that 

you’re about to go to the previous or next folder, 

respectively. Release the button when you see the 

flashing, and you will jump to the next or previous 

folder. The folders are browsed alphabetically/

numerically.

If you see the column lights flashing, but don’t 

want to change folders, turn the knob up or down to cancel the action.

Tip

:

 

If  you  can’t  quite  reach  the  top  or 
bottom file, just let go of the button, 
turn  the  knob  to  a  new  position, 
and  then  resume  the  knob 
motion.  This  will  also  change  the 
playback  volume,  so  another 
technique  is  to  turn  the  knob 
rapidly to advance by more files.
