load_cps_tbl :: FilePath -> IO [(Midi, Double)]

Load possibly sparse and possibly one-to-many (midi-note-number,cps-frequency) table from Csv file.

load_cps_tbl "/home/rohan/dr.csv"

load_tuning_scl :: String -> IO Tuning

Load scala scl file as Tuning.

type Load_Tuning_Opt = (String, Double, Midi)

cps = (tuning-name,frequency-zero,midi-note-number-of-f0) d12 = (tuning-name,cents-deviation,midi-note-offset)

load_tuning_cps :: Load_Tuning_Opt -> IO Sparse_Midi_Tuning_f

Load scala file and apply cps_midi_tuning_f.

load_tuning_d12 :: Load_Tuning_Opt -> IO Sparse_Midi_Tuning_f

Load scala file and apply d12_midi_tuning_f.

load_tuning_tbl :: Load_Tuning_Opt -> IO Sparse_Midi_Tuning_f

Lookup first matching element in table.

type Choose_f st t = [t] -> st -> (t, st)

default_choose_f :: RandomGen g => Choose_f g t

Randomly choose from elements in table, equal weighting.

load_tuning_tbl_st :: Choose_f st (Midi, Double) -> Load_Tuning_Opt -> IO (Sparse_Midi_Tuning_St_f st)

Load tuning table with stateful selection function for one-to-many entries.

load_tuning_ty :: String -> Load_Tuning_Opt -> IO Sparse_Midi_Tuning_f

load_tuning_st_ty :: String -> Load_Tuning_Opt -> IO (Sparse_Midi_Tuning_St_f StdGen)
