Autoclear gives you the option to have enormous delay based effects that stop when you need them to, for example, when the next note hits. It’s something you have to hear to really get your head around. Once you’ve used it you’ll wonder how you ever used an echo without it

Diffusion is a cool effect that smears the delay sound, taking it into the realm of a reverb, it’s a way of knocking off some of the hard edges. Just like a reverb you can also adjust the size of the space and widen the stereo image.

Envelop Follow allows you to control how the delay evolves over time. You can have the delay time, feedback, and mix change over time with control over when that happens using ceiling and and release time.
