Chorus
Chorus is a taste of the Airwindows modulation effects, for free.
It’s got speed and depth controls, dry/wet, and an additional brightness control to offset clarity losses from its interpolation. Back in the day, Airwindows was pretty proud of this fancy interpolation, in the belief that coders were typically just picking the nearest sample for their delay tap and calling it a day. Doing the interpolation gives you a much deeper, more fluid sound, though it darkens the tone a bit.
Come to think of it, other coders may still be picking the nearest sample for all I know. Guess you’ll have to shoot this out against typical DAW choruses and see what happens.
