|The datatypes for MIDI Files and MIDI Events
|An empty MIDI file.
|Convert all NoteOn p 0 to NoteOff p 64.
The latter one is easier to process.
|Convert all NoteOff p 64 to NoteOn p 0.
The latter one can be encoded more efficiently using the running status.
|Show the T with one event per line,
suited for comparing MIDIFiles with diff.
Can this be replaced by Sound.MIDI.Load.showFile?
|A hack that changes the velocities by a rational factor.
|Change the time base.
|Sort MIDI note events lexicographically.
This is to make MIDI files unique
and robust against changes in the computation.
In principle Performance.merge should handle this
but due to rounding errors in Float
the order of note events still depends on some internal issues.
The sample rate of MIDI events should be coarse enough
to assert unique results.
|progChangeBeforeSetTempo :: T -> T||Source|
|Old versions of Haskore.Interface.MIDI.Write
wrote MIDIEvent.ProgramChange and SetTempo
once at the beginning of a file in that order.
The current version supports multiple MIDIEvent.ProgramChanges in a track and
thus a MIDIEvent.ProgramChange is set immediately before a note.
Because of this a MIDIEvent.ProgramChange is now always after a SetTempo.
For checking equivalence with old MIDI files we can switch this back.
