A multi-tap delay is a delay line where multiple 'taps' or outputs are
taken from a delay buffer at different points, and the taps are then
summed with the original. Multi-tap delays are great for creating
rhythmic delay patterns, but they can also be used to create sound
fields of such density that they start to take on some of the qualities
we'd more usually associate with reverb. - Geoff Smith, Sound on Sound
In AudioKit, you can create a multitap easily through creating a function
that mixes together several delays and gains.
