Audio Connections

The audio outputs can function several ways, depending on which ones have cables plugged in. If 
cables are plugged into both outputs they will provide separate left and right stereo signals. If only the 
right output is plugged in, it will provide a mono (combined right and left) signal. If only the left jack is
used and a TRS cable is plugged in, it will output left and right signals on the tip and ring contacts, 
respectively, allowing headphones to be used.

SD Card

The SD card can be removed from its slot removed using tweezers or needlenose pliers (power down 
the SquishBox first). A complete image of the latest SquishBox software, including the default 
soundfonts and banks, can be obtained at 

geekfunklabs.com/products/squishbox

You can write this 

image to the SD card using 

Win32DiskImager

 on Windows, or the 

dd

 command on MacOS or Linux, 

but this will erase any other data you have on the SD card. You cannot copy soundfonts or bank files 
directly onto the SD card and use them on the SquishBox – only the /boot partition is visible to other 
operating systems.

Usage

Navigating Patches/Menus

Tap the buttons to switch between patches. Long-press (hold >2sec) the right button for the 
main menu, long-press the right for system-related tasks.

In menus, tap the buttons to switch options. Long-pressing right will select an option, long-
pressing left will go back/cancel.

Some menus allow you to change a numerical setting. Tapping buttons increases/decreases the 
value, holding buttons changes the value quickly. If you don’t press any buttons >5sec you’ll be
asked whether to set the current value – long-press right to confirm, left to cancel.

Some menus allow you to enter text. Tap the buttons to change the current character. Long-hold 
the buttons to move the cursor right or left. If you move the cursor to the end of the text, it will 
change to an accept ( ) symbol, at which point you can long-press right to accept your text. 
Tapping left will select the delete ( ) character, which allows you to delete characters by long-
pressing left. Pressing no buttons for >5sec cancels your entry.

Refresh Bank: Holding the right button for >5sec will re-load the current bank file.

Panic Restart: Holding the left button for >5sec will stop all sound and restart the software.
