I might be thinking of delay with substantial feedback or wetness or both 🤔

What is the interplay between these parameters of delay?

On a spectrum, between

no delay {delay(time: 0s, feedback: 0, wetness 0)}

and

substantial echoey {delay(time: 0.5s, feedback: 100, dry/wetness: 100)}

Wouldnt you say theres something about the latter that could lend itself to sedating the listener or at least theres something more mentally effortful about the brain parsing it that might promote that type of response
