csv_midi_note_data_hdr :: [String] Source #
The required header field.
csv_midi_note_data_read' :: (Read t, Real t, Read n, Real n) => (m, m) -> FilePath -> IO [(t, Either m String, n, n)] Source #
Midi note data, header is time,on/off,note,velocity.
Translation values for on/off are consulted.

csv_midi_note_data_read' ("ON","OFF") fn :: IO [(Double,Either String String,Double,Double)]csv_midi_note_data_read :: (Read t, Real t, Read n, Real n) => (m, m) -> FilePath -> IO [(t, m, n, n)] Source #
Variant of csv_midi_note_data_read' that errors on non on/off data.
midi_tseq_read :: (Read t, Real t, Read n, Real n) => FilePath -> IO (Tseq t (On_Off (n, n))) Source #
Tseq form of csv_read_midi_note_data.
midi_tseq_to_midi_wseq :: (Num t, Eq n) => Tseq t (On_Off (n, n)) -> Wseq t (n, n) Source #
Translate from Tseq form to Wseq form.
midi_wseq_to_midi_tseq :: (Num t, Ord t) => Wseq t (n, n) -> Tseq t (On_Off (n, n)) Source #
Off-velocity is zero.
