The Reverse switch (abbreviated Rev in Ronin’s window) causes the delay line to record and play back in the
opposite direction. The effect of the Reverse switch is slightly different depending on whether or not the Loop
switch is turned on. If the Loop switch is turned on, turning on the Reverse switch causes any audio currently
being played in the loop to play backwards, over and over. You can record new audio over the backwards
audio, and then turn the Reverse switch off to hear the original audio played forwards again and the newly
recorded audio played backwards. If the Loop switch is not turned on, you will hear the audio currently in the
delay line played backwards once, and then all subsequent audio will be played forwards, because the new
audio coming into the delay line is being recorded in the same direction as the audio coming out of the delay
line. Yes, this is a little confusing at first, but it becomes more understandable (and a lot of fun) as you play
with it.
