jumpIn
From TidalCycles userbase
jumpIn
takes the identifier of the ControlPattern track and an integer cycleCount. It will jump unaligned into the given pattern after cycleCount cycles have completed.
Example: Say you have this:
d1 $ sound "hh*4"
d2 $ sound "bd" --have a beat on the 1 for orientation
Then the subdivision on the hi-hat will increase 2 cycles after evaluation of the next line:
jumpIn 1 2 $ sound "hh*8" --`1` because `d1` is defined `let d1 = p 1`
The transition will not align with the beat on cycle boundary.
