Overview

The SquishBox is a synthesizer running on a Raspberry Pi built into a stompbox. It will take MIDI
input from controllers plugged into its USB ports and output instrument sounds on its 1/4" outputs. The
sounds come from soundfonts, a widely-available sample-based sound file format that can contain
multiple instruments (referred to as presets).
The buttons on the SquishBox allow you to switch between patches, which activate one or more
instruments and can also specify how the keys, buttons, knobs, and pads on your controller should be
routed to the instruments, turn on effects, send CC and SYSEX messages, and more. Patches are stored
in bank files, and the number of patches and banks you can have is more or less unlimited. A selection
of soundfonts and bank files are included, and you can write your own bank files and add soundfonts to
suit your specific performance needs.
