- All Implemented Interfaces:
- Editable, Instrument, Namable, OutputProvider, Transposable, AttributeBuildable, DirectorySettable, HandleSpecialXMLTag
public class TransposingSamplePlayingInstrumentWithAmplitudeMap
- extends TransposingSamplePlayingInstrument
This subclass of TransposingSamplePlayingInstrument overrides
getAlternativeSampleIndex() to map note 60 to three different samples based
on amplitude. Notice that one sample is mapped to 60. Two additional samples
are mapped to pitches 200 and 201, which we never expect to play directly.
They serve as convenient places to stash alternative samples within the
existing API.
The logic of mapping quiet, medium, loud versions of middle c is implemented
in getAlternativeSampleIndex()

getAlternativeSampleIndex
public int getAlternativeSampleIndex(int pitchIndex,
double timeStretch,
double[] data)
- Precondition: pitchIndex points to a valid sample, previously loaded with
addSamplePitch(). Override this method to point to a different valid
sample index. For example, you might store a loud sample at pitchIndex 60
and quiet sample at index 200 (ie some pitch index you'd never bang
directly), and if the amplitude of data[] < 0.3 return 200 for this
pitchIndex, else return 60)
public int getAlternativeSampleIndex(int pitchIndex, double timeStretch, double[] data) {
double amp = data[2];
if (pitchIndex == 60 && amp < 0.4) {
return 201;
}
if (pitchIndex == 60 && amp > 0.7) {
return 200;
}
return pitchIndex;
}
- Overrides:
getAlternativeSampleIndex
in class SimpleSamplePlayingInstrument
- Returns:
- valid index to use instead of pitchIndex.
