1. wantNote :: (Alist -> Bool) -> BBDB -> Bool

   bbdb	Database.BBDB

   Notes inside a BBDB record are awkward to get at. This helper function digs into the record and applies a function to each Alist element of the record. It returns true if it any of the Alists in the note return true. For example:

   hasBirthday :: BBDB -> Bool
   hasBirthday = wantNote (\x -> key x == "birthday")
   

   will return True for any BBDB record that has a "birthday" key in it's notes field

2. maximumByNote :: String -> (a -> a -> Ordering) -> [a] -> a

   boolsimplifier	Data.BoolSimplifier

   No documentation available.

3. doesNotExistErrorType :: IOErrorType

   classy-prelude-yesod	ClassyPrelude.Yesod

   I/O error where the operation failed because one of its arguments does not exist.

4. isDoesNotExistError :: IOError -> Bool

   classy-prelude-yesod	ClassyPrelude.Yesod

   An error indicating that an IO operation failed because one of its arguments does not exist.

5. isDoesNotExistErrorType :: IOErrorType -> Bool

   classy-prelude-yesod	ClassyPrelude.Yesod

   I/O error where the operation failed because one of its arguments does not exist.

6. onotElem :: MonoFoldable mono => Element mono -> mono -> Bool

   classy-prelude-yesod	ClassyPrelude.Yesod

   Checks if the monomorphic container does not include the supplied element.

7. closestNote :: Float -> Float

   dobutokO2	DobutokO.Sound.Functional.Basics

   Returns the closest note to the given frequency in Hz.

8. dNote :: Int -> Float -> Maybe Float

   dobutokO2	DobutokO.Sound.Functional.Basics

   Function to get from the number of semi-tones and a note a Maybe note for the second lower note in the interval if any. If there is no need to obtain such a note, then the result is Nothing.

9. neighbourNotes :: Float -> Vector Float -> (Float, Float)

   dobutokO2	DobutokO.Sound.Functional.Basics

   Function returns either the nearest two musical notes if frequency is higher than one for C0 and lower than one for B8 or the nearest note duplicated in a tuple.

10. pureQuintNote :: Float -> Float

    dobutokO2	DobutokO.Sound.Functional.Basics

    Returns a pure quint lower than the given note.
