V. Operation

• Key and Harmony Selection: Use the encoder to select the song's Key to match the HARMONY. If your singing is out of tune, the HARMONY will follow your pitch. Keys C, D, E, F, G, A, B are available. The dot indicates a sharp (#), toggled by pressing the Key Select encoder. The Major/Minor switch adjusts the mode.
• Center Silencer: The "CENTER SILENCER" button can remove vocals from audio inputs, most effective for vocals centered in a stereo mix. It works by phase-canceling the center channel of a stereo signal.
• Footswitch Modes: You can set the footswitches to Latching (normal on/off) or Momentary (effect active only while pressed) by powering on the unit while holding one or both footswitches. A single LED flash on startup indicates Latching mode; four flashes indicate Momentary mode.
