Genarates barline type from the LilyPond syntax for the given barline from format "barlineType".

int CAMidiImport::clefOffsetFromLilyPond ( const QString  constClef) [private]

Returns the Canorus octava or whichever interval above or below the clef.

void CAMidiImport::closeFile ( )

References CAFile::file().

Here is the call graph for this function:

void CAMidiImport::combineMidiFileEvents ( ) [private]

Combines the midi on/off events and reduces them to a note with a length. Note off events are, which can also be a note on with velocity zero, are thus eaten up and are invalidated by pitch -1.

todo: rounding fine grained note lenghts, dispersing small rests

todo: combine concurrent notes to chords or export concurrent notes to a next voice.

Returns the key signature gender from format \genderType.

References CADiatonicKey::Major, and CADiatonicKey::Minor.

void CAMidiImport::exportNonChordsToOtherVoices ( ) [private]

If not a chord move overlapping notes to other voices.

The algorithm is this: For every note on event we look if there are follow up events that overlap. If there is a overlap the second note will be moved to a higher (index of the) voice, so high, where it can be stay without overlap.

Here is the caller graph for this function:

CAMusElement * CAMidiImport::findSharedElement ( CAMusElement *  elt) [private]

Gathers a list of music elements with the given element's start time and returns the first music element in the gathered list with the same attributes.

This method is usually called when voices have "shared" music elements (barlines, clefs etc.). However, in LilyPond syntax the music element can/should be present in all the voices. This function finds this shared music element, if it already exists.

If the music element with the same properties exists, user should delete its own instance and add an already existing instance of the returned shared music element to the voice.
