Per Cliff,
"The LFOs actually modulate the tape speed. It’s the same as attaching a modifier to the tape speed.
This is because in an actual tape deck the tape speed is what is typically subject to variation. Wow occurs due to variation in motor speed (or belt/pulley, etc.) and flutter is due to capstan and pinch roller. Wow varies the tape speed slowly, flutter is a high-frequency variation in speed. The actual delay time is very stable since the heads are stationary and the tape is taught between the heads. Delay modulation due to tape stretching is negligible."
So when you go to the tape config is modulating the motor speed, other configs modulate the delay time.
