Usage

1. Example

   a = FoscTransposition(4);
   p = FoscPitch(60);
   a.(p).pitchNumber;

   64.0

2. Example

   a = FoscTransposition(4);
   p = [FoscPitch(60), FoscPitch(64), FoscPitch(67)];
   a.(p).collect { |each| each.pitchNumber };

   [ 64.0, 68.0, 71.0 ]

3. Only transpose masked pitches.

   FIXME: ERROR: Class not defined

   a = FoscTransposition(4, mask: FoscPitchClassMask(#[0,7]));
   p = [FoscPitch(60), FoscPitch(64), FoscPitch(67)];
   a.(p).collect { |each| each.pitchNumber };

4. Example

   a = FoscTransposition(4);
   p = FoscPitchSegment([FoscPitch(60), FoscPitch(64), FoscPitch(67)]);
   a.(p).str;

   <e' af' b'>
