[Class]

midi-file

A subclass of midi-stream that implements input and output to MIDI files. A midi-file is automatically created when you specify a file with a ".midi" or ".mid" extension.

midi-file supports the following slot initializations:

:versioning boolean

If true then each time the file is written its output file name will include a version number -n appended to its name, i.e. test-1.mid, test-2.mid and so on. The version number is automatically incremented each time the file is written and insures that multiple "takes" of the same file can be generated without overwriting the contents of earlier versions.

:divisions integer

The number of divisions per quarter note. Defaults to 480.

:tempo number

The MIDI tempo of the file. Defaults to the tempo of 60 bpm.

:timesig (numerator denominator)

The time signature for the file. Defaults to (4 4). The time signature list may contain up to four values: (numerator denominator [clocks-per-quarter] [32nds])

See midi-stream and play for additional keyword initializations.
