stut

Type: stut :: Pattern Integer -> Pattern Double -> Pattern Rational -> ControlPattern -> ControlPattern

stut applies a type of delay to a pattern. It has three parameters, which could be called depth, feedback and time. Depth is an integer and the others floating point. This adds a bit of echo:

d1 $ stut 4 0.5 0.2 $ sound "bd sn"

The above results in 4 repeats (the original plus 3 echoes), each echo 50% (that's the 0.5) quieter than the last, spread out over 1/5th (that's the 0.2) of a cycle.

It is possible to reverse the echo:

d1 $ stut 4 0.5 (-0.2) $ sound "bd sn"

stutWith

Type: stutWith :: Pattern Int -> Pattern Time -> (Pattern a -> Pattern a) -> Pattern a -> Pattern a

stutWith (formerly known as stut') is similar to stut described above, but instead of just decreasing volume to produce echoes, stutWith applies a function each step and overlays the result delayed by the given time.

d1 $ stutWith 2 (1/3) (# vowel "{a e i o u}%2") $ sound "bd sn"

In this case there are two overlays delayed by 1/3 of a cycle, where each has the vowel filter applied.

d1 $ stutWith 3 (1/6) (|* speed "1.5") $ sound "arpy arpy:2"

In the above, three versions are put on top, with each step getting higher in pitch as |* speed "1.5" is successively applied.

Note that the parameters for stut and stutWith don't currently behave the same way - the latter takes the number of echoes rather than the total number of repeats, and a time between repeats rather than the total time between the first and last repeat. stutWith will probably be changed to match stut in the next Tidal release.
