craft a chorus
Chorus is related to flanging – push the delay’s time up to (and over) 25 milliseconds to get into this territory. Crucially, you’ll notice that as you transition into chorusing, and then crank the delay time up towards 35 milliseconds and on towards 50, you’ll get noticeable pitching effects. This is what gives this effect its name – it’s like a group of people or instruments together, all very slightly out of pitch. Chorus is also a great widener of the signal. Again, experiment with feedback, modulation time and amount, and tweak the dry/wet mix if you want widening without pitch effects.
