Function Documentation

Real AbsDuration

(

Real

x )

Calculate the absolute duration of a Real without the implicit tempo scale applied, as a fraction of a whole note.

Definition at line 49 of file Rhythm.cpp.

References Return.

{
        Rhythm(y);
        Return y.absDuration();
}

Real AbsDuration

(

Rhythm

x )

Calculate the absolute duration of a Rhythm without the implicit tempo scale applied, as a fraction of a whole note.

Definition at line 60 of file Rhythm.cpp.

References Rhythm::absDuration(), and Return.

{
        Return y.absDuration();
}

Real Duration

(

Real

x )

Calculate the actual duration of a Real with the implicit tempo scale applied, as a fraction of a whole note.

For example, SetTempoScale( 0.5 ); Print( Duration( 1.0/4.0 ) ); prints 0.125.

Definition at line 37 of file Rhythm.cpp.

References Return.

{
        Rhythm(y);
        Return y.duration();
}

Real Duration

(

Rhythm

x )

Calculate the actual duration of a Rhythm with the implicit tempo scale applied, as a fraction of a whole note.

Definition at line 55 of file Rhythm.cpp.

References Rhythm::absDuration(), and Return.

{
        Return y.absDuration();
}

Real metronome	(	Rhythm	B,
		Real	T
	)

Calculate the tempo coefficient corresponding to some rhythmic duration B at some tempo T.

B can be expressed as a ratio of reals, e.g., 1.0/4.0 for a quarternote. The expression metronome( 1.0/4.0, 60.0 ) returns the tempo coefficient for "quarter note gets the beat and there are sixty beats per minute". Hence, it returns 1.0.

Definition at line 32 of file Rhythm.cpp.

References Rhythm::absDuration(), and Return.

{
        Return( 1.0 / (4.0 * B.absDuration()) * 60.0 / T );
}

Void SetTempoScale

(

Real

ts )

Set the tempo used by all instances of Rhythm.

Definition at line 27 of file Rhythm.cpp.

References Rhythm::tempo().

{
        Rhythm::tempo(ts);
