  • How do I reinitialize my QuadraSynth?

    Power on while holding: Quad Buttons 1 and 4.

    Evidence: Program and Mix modes will both show "0" as the selected number with a name made of two quotation marks. An initialized program will be active consisting of a single pure sinewave.
    Note: Does NOT clear memory
    Resets the QuadraSynth's Global functions, but leaves the Mix, Program, and Effect memory intact in the User Bank. The Preset Bank is unaffected, as it is permanently stored in the keyboard's ROM (Read Only Memory).
