crush :: Pattern Double -> ControlPattern
crush turns a number pattern into a control pattern that creates a bit-crushing effect.
Use values between 1 and 16, where 1 results in a drastic bit reduction, and 16 results in barely any reduction.
You can also use negative values for a slightly different effect.
