    Stereo lo-fi chorus/vibrato with clockable LFO and character shaping.

    Main controls modulation rate, X controls modulation depth, Y controls
    Character

    (lo-fi degradation <-> compression coloration). Switch up selects vibrato
    mode

    (fully wet), middle selects chorus mode (dry/wet blend), and a momentary
    move

    to down cycles LFO shape (triangle, sine, random drift).
