Just for fun, you can adjust the playing rate down to nearly zero, or up to three times as fast as normal. This change does not affect the timer. Tapping on the rate display (the little box above the slider) will reset the rate value to normal (i.e., "×1.0"). Rate value adjustments apply the next time the player starts, rather than during a passage while it is playing (or having an adjustment start the player).
NOTE WELL: This form of rate adjustment does not change the pitch of the music (i.e., its "chipmunkiness").
(And why a sea turtle instead of the conventional tortoise? Cuz style.)
