Detailed Description

Class used for transposing a set of notes for the given interval.

Licensed under the GNU GENERAL PUBLIC LICENSE. See COPYING for details.

This is a control class used for making a transposition of a set of music elements, contexts or even the whole score sheet.

Use: 1) Create a CATranspose class 2) Pass the music elements you want to transpose in the constructor or by calling addMusElement() or addContext(). 3) Transpose the elements by calling transposeByKeySig(), transposeByInterval() or transposeBySemitones()

		CADiatonicKey	to,
		int	direction
	)

Transposes the music elements from the given key signature from to the key signature to in the given direction. Direction can be 1 for up or -1 for down.
