fromMaybes :: [Maybe a] -> Pattern atidal Sound.Tidal.Boot 'fromMaybes; is similar to fromList, but allows values to be optional using the Maybe type, so that Nothing results in gaps in the pattern. The following are equivalent: > d1 $ n (fromMaybes [Just 0, Nothing, Just 2]) # s "superpiano" > d1 $ n "0 ~ 2" # s "superpiano"
