Are There Trails When Switching Algorithms or Bypassing the Eternity?
When switching between modes (Live or Preset) or switching between presets, the pedal automatically enters a "graceful transition" state, the Bypass LED will begin to flash letting you know that the Repeats knob is gracefully returning to its new setting. This only applies when staying within the same algorithm and staying on the same subdivision setting. If you're switching between algorithms or subdivision settings, you will not have delay trails.
When bypassing the Eternity, trails will always be active.
