Detailed Description

This is a utility class to facilitate transposition. It supports:

Correct chromatic interval transposition, including microtonal and irregular custom key signatures.
Transposition by EDO steps. EDO stands for Equal Division of the Octave, typically 12 per octave (12-EDO). But microtonal scales can be many more than that. Common values are 24-EDO (quarter tones), 19-EDO, 31-EDO, 48-EDO, and even 96-EDO.
Simplification of note spelling.

The most common ways to get an instance of FCTransposer are with FCNote::GetTransposer or FCChord::GetTransposer. Transposers returned by these classes automatically update the class when you call the transposition functions. You can call the transposition functions as often as you need to, and the target entity continues to be updated. However, do not reuse a transposer created by one instance with another instance that did not create it. Instead, create a new instance for the new target. Also, like any object obtained with a Get verb, you must not use it after the object that created it goes out of scope.

Warning: Finale does not support microtonal chords. FCChord transposition only works correctly with 12-EDO key signatures. (All standard key signatures are 12-EDO, as are many custom key signatures such as klezmer modes, which FCTransposer also handles correctly.)

You can also directly create an instance of FCTransposer by passing displacement and raise/lower values to the constructor. You can then retrieve the result of the transposition with the GetDisplacement and GetRaiseLower methods.

Constructor & Destructor Documentation

◆ FCTransposer()

FCTransposer::FCTransposer	(	eHarmLev	displacement,
		eHarmAlt	raiselower,
		const FCKeySignature *	key )

inline

The constructor.

Lua-supported (0.67).

Parameters

displacement	The scale displacement value.
raiselower	The chromatic alteration value.
key	The key signature to use for transposition.

Member Function Documentation

◆ ChromaticTranspose()

bool FCTransposer::ChromaticTranspose	(	eHarmLev	interval,
		eHarmAlt	alteration,
		bool	simplify = false )

inline

Transposes the target chromatically by the input chromatic interval.

In Finale, chromatic intervals are defined by a diatonic displacement (0 = unison, 1 = second, 2 = third, etc.) and a chromatic alteration. Major and perfect intervals have a chromatic alteration of 0. So for example, {2, -1} is up a minor third, {3, 0} is up a perfect fourth, {5, 1} is up an augmented sixth, etc. Reversing the signs of both values in the pair allows for downwards transposition.

Lua-supported (0.67).

Parameters

interval	the diatonic displacement of the transposition interval.
alteration	the chromatic alteration for the interval.
simplify	if true, simplify the spelling. This parameter is optional and defaults to false.

Returns: success or failure (if the resultant magnitude of RaiseLower would exceed 7)

◆ DefaultEnharmonicTranspose()

bool FCTransposer::DefaultEnharmonicTranspose ( )

inline

Transpose the target enharmonically in Finale's default direction.

This function is useful when performing an unlinked enharmonic flip in a part. Only a default enharmonic flip unlinks. Any other enharmonic flip appears in the score as well. This code is based on observed behavior in Finale 27.

Lua-supported (0.67).

Returns: success or failure (if the resultant magnitude of RaiseLower would exceed 7)

◆ DiatonicTranspose()

void FCTransposer::DiatonicTranspose ( eHarmLev interval )

inline

Transpose the target diatonically by the given interval displacement.

Lua-supported (0.67).

Parameters

interval 0 = unison, 1 = up a diatonic second, -2 = down a diatonic third, etc.

◆ EDOStepTranspose()

bool FCTransposer::EDOStepTranspose ( twobyte numberofsteps )

inline

Transposes the target by the input number of EDO steps and simplifies the spelling.

Warning: The hard-coded Finale limit for RaiseLower values of +/-7 means that it is not possible to represent certain notes in EDO systems with extremely small microtonal increments. The most common of these is 96-EDO. With 8 EDO steps per half-step, Finale cannot reach the middle note of a diatonic whole step. Composers who use Finale for 96-EDO (or higher) use visual workarounds for these situations. This function never fails for standard scales and key signatures.

Lua-supported (0.67).

Parameters

numberofsteps positive = up, negative = down.

Returns: success or failure (if no representation exists that would not exceed magnitude 7 for RaiseLower.)

◆ EnharmonicTranspose()

bool FCTransposer::EnharmonicTranspose ( twobyte direction )

inline

Transpose the target enharmonically in the given direction.

In some microtone systems this yields a different result than transposing by a diminished 2nd. Failure occurs if the target's RaiseLower value exceeds a magnitude of 7. This is a hard-coded limit in Finale.

Lua-supported (0.67).

Parameters

direction positive = up, negative = down (normally 1 or -1, but any positive or negative numbers work the same as 1 or -1.)

Returns: success or failure (if the resultant magnitude of RaiseLower would exceed 7)

◆ GetDisplacement()

eHarmLev FCTransposer::GetDisplacement ( ) const

inline

Gets the current displacement value. Before transposition, it is the value passed in on the constructor. After transposition it is the transposed value.

On Lua, this function throws a runtime error if the FCTransposer instance was not explictly constructed with displacement and RaiseLower values. Other clients receive 0.

Lua-supported (also as read-only property) (0.67).

◆ GetRaiseLower()

eHarmLev FCTransposer::GetRaiseLower ( ) const

inline

Gets the current chromatic alteration value. Before transposition, it is the value passed in on the constructor. After transposition it is the transposed value.

On Lua, this function throws a runtime error if the FCTransposer instance was not explictly constructed with displacement and RaiseLower values. Other clients receive 0.

Lua-supported (also as read-only property) (0.67).

◆ OctaveTranspose()

void FCTransposer::OctaveTranspose ( twobyte numberofoctaves )

inline

Transpose the target by the given number of octaves.

Lua-supported (0.67).

Parameters

numberofoctaves 0 = no change, 1 = up an octave, -2 = down 2 octaves, etc.

◆ SimplifySpelling()

bool FCTransposer::SimplifySpelling ( )

inline

Simplifies the note spelling the most it can using enharmonic transposition.

See EDOStepTranspose for an explananation of why this function can fail. However, if the target is already representable in Finale, this function cannot fail. It can only fail if the target currently is not representable (i.e, its RaiseLower value has magnitude greater than 7.) In that case, this function transforms it to a representable spelling with RaiseLower less than or equal to 7, or it fails if that is not possible.

Returns: success or failure (if the target cannot be represented in Finale.)
