Meg of Drive Thru Society
Tap the red edge on the white line. Build to the bridge.
Tap when the red edge of a note meets the white line. You can tap anywhere in that lane, including below the pads. Hold red ribbons until their end.
Positive values bring notes to the line later. Adjust before replaying a passage. Headphones with a cable usually make timing easier.
System reduced-motion preferences are also respected. Notes always keep moving.
