Synopsis

toSeekableFile Source

Arguments

:: FilePath

file name

-> T 
-> IO () 

Directly write to a file. Since chunks lengths are not known before writing, we need to seek in a file. Thus you cannot write to pipes with this function.

toFile Source

Arguments

:: FilePath

file name

-> T 
-> IO () 

The function toFile is the main function for writing T values to an actual file.

toByteList :: T -> ByteList Source

Convert a MIDI file to a ByteList.

toByteString :: T -> ByteString Source

Convert a MIDI file to a lazy ByteString.

toCompressedByteString :: T -> ByteString Source

Convert a MIDI file to a lazy ByteString. It converts NoteOff p 64 to NoteOn p 0 and then uses the running MIDI status in order to compress the file.
