Type: fix :: (ControlPattern -> ControlPattern) -> ControlPattern -> ControlPattern -> ControlPattern

The fix function applies another function to matching events in a pattern of controls. fix is contrast where the false-branching function is set to the identity id.

For example:

d1 $ slow 2 $ fix (# crush 3) (n "[1,4]") $ n "0 1 2 3 4 5 6" # sound "arpy"

The above only adds the crush control when the n control is set to either 1 or 4.

You can be quite specific, for example fix (hurry 2) (s "drum" # n "1") to apply the function hurry 2 to sample 1 of the drum sampleset, and leave the rest as they are.

unfix

unfix is fix but only applies when the testing pattern is not a match.
