This pedalboard examplifies the tetr4-switch usage. Tetr4-switch is assigned to the Footswitch B on the first page. Clicking to it, it will change between four "presets": - Preset 1: Clean (chorus) - Preset 2: Base (dist) - Preset 2: Solo (dist + fuzz + octaver + delay + reverb) - Preset 2: Base 2 (dist + delay + reverb) Click on "Manage CV Ports" to see the CV names.
