Type: degrade :: Pattern a -> Pattern a

degrade randomly removes events from a pattern, 50% of the time. Example usage:

d1 $ slow 2 $ degrade $ sound "[[[feel:5*8,feel*3] feel:3*8], feel*4]"
   # accelerate "-6"
   # speed "2"

degradeBy

Type: degradeBy :: Double -> Pattern a -> Pattern a

Similarly to degrade, degradeBy allows you to control the percentage of events that are removed. For example, to remove events 90% of the time:

d1 $ slow 2 $ degradeBy 0.9 $ sound "[[[feel:5*8,feel*3] feel:3*8], feel*4]"
   # accelerate "-6"
   # speed "2"

unDegradeBy

Type: unDegradeBy :: Double -> Pattern a -> Pattern a

unDegradeBy is degradeBy but with the percentage describing how many events to keep on average not remove.
