Sound Character and Delay Behavior
Because the delay time is set by clock speed, changing the time shifts the pitch of the repeats in a way that resembles tape. Sinevibes says the pitch glides during delay time changes do not affect the material already in the loop. This behavior is what produces the classic dub delay effect.
The degradation that comes with longer delay times is part of the design. Repeats become more lo-fi as the time increases, which suits dub, lo-fi and experimental processing where the decay is part of the sound.
The feedback section includes filtering and a limiter, so the loop can run for a long time without the signal breaking up.
