Tries to assume the correct accidental for the alien notes in the key signature. Currently this function searches for disalterations (eg. cis -> c, where c is the note in the scale). The algorithm solves the toggling notes (eg. e es e -> e dis e) and transition notes (eg. e dis d -> e es d).

importMidiEvents()

void CAMidiImport::importMidiEvents ( )

private

The midi file is opened by calling the pmidi wrapper function pmidi_open_midi_file(), then, in a polling loop, the wrapper function pmidi_parse_midi_file() brings out the relevant midi events which are stored in the array _allChannelsEvents[]. All time signatures are stored in the array _allChannelsTimeSignatures[]. The work of pmidi and the wrapper is done then.

All time values are scaled here to canorus' own music time scale.

Further processing is referred to function writeMidiFileEventsToScore_New().

importMidiNotes()

QList< QList< CAMidiNote * > > CAMidiImport::importMidiNotes

(

)

Imports the given MIDI file and returns a list of CAMidiNote objects sorted by timeStart per channel.

This function is usually called when raw MIDI operations are done and the actual notes etc. aren't needed.

Warning

This function returns notes only (without rests).

Only abstract note times are preserved. Real MIDI note times (in miliseconds) are lost.

This function is a duplicat in CAKeybdInput! Should be moved to CADiatonicPitch an be reused.

This function looks up the current key signiture. Then it computes the proper accidentials for the note.

This function should be somewhere else, maybe in CADiatonicPitch ?

Apropo program support at midi import: Now the last effective program assignement per voice will make it through. A separation in voices regarding the midi program is note yet implemented.
