Gamechanger Audio AUTO Chorus – Expressive Pitch- & Dynamics-Reactive Modulation Pedal

The AUTO Chorus reinvents the classic modulation pedal—dynamically responding to how you play. With three distinct algorithms (Chorus, Ensemble, Flange), three wave shapes, and intuitive touch-sensitive routing, this pedal puts sonic expression at your feet—crafted to elevate your tone at Soundium.

Key Features

• Three modulation algorithms: Classic Chorus, rich Ensemble, and sweeping Flanger for diverse textures
• Four core controls + attenuators: Level, Depth, Rate, Feedback knobs, each with a mini-attenuverter to assign dynamics or pitch modulation
• Performance-driven automation: Envelope (Dynamics) and Pitch tracking engines let your playing shape parameters in real time
• Patchable CV-style routing: Use included patch cables to route modulation signals into any parameter for modular-like creativity
• Stereo/mono I/O and flexible signal selection: Works with TS or TRS cables; input switchable between Instrument, Line, or Eurorack levels
• Footswitch serves dual role: Toggle between classic static effect and automated mode—with “Track Tempo” feature for dynamic rate syncing via strumming

Customer Benefits

Whether you're after subtle vibrato or dramatic flange sweeps, AUTO Chorus breathes emotion into modulation. Its unique touch-responsive behavior allows modulation to follow your expression—perfect for ambient textures, live sonic sculpting, or expressive studio layering.
