我们可以使用Soundfont创建自己的作品吗?我正在使用Tabla Soundfont和JFugue创建新的合成并播放它。但是从Soundbank加载乐器后,程序仍然会播放Piano的默认声音。如何从声音库中启用乐器。 请检查以下代码:
import org.jfugue.*;
import java.io.File;
import java.io.FileInputStream;
import javax.sound.midi.Instrument;
import javax.sound.midi.MidiDevice;
import javax.sound.midi.MidiSystem;
import javax.sound.midi.Sequence;
import javax.sound.midi.Sequencer;
import javax.sound.midi.Soundbank;
import javax.sound.midi.Synthesizer;
import com.sun.media.sound.SF2Soundbank;
public class SF2Demo {
static Synthesizer synthesizer;
static Sequencer sequencer;
static MidiDevice dev;
public static void main(String[] args) {
// TODO Auto-generated method stub
try {
synthesizer=MidiSystem.getSynthesizer();
synthesizer.open();
}
catch (Exception e) {e.printStackTrace();}
loadSF2();
Player player = new Player();
Pattern pattern = new Pattern("C#3 D#3 D#3 C#3 C#3 D#3 D#3 C#3");//"Dha Dhin Dhin Dha Dha Dhin Dhin Dha " Tabla Pattern
player.play(pattern);
}
private static void loadSF2() {
String filename;
boolean duringInitialLoad=false;
try{
filename="C:/Javapro/tabla-sf2/tabla.sf2";
File f= new File(filename);
if(f.exists()){
Soundbank soundbank=new SF2Soundbank(
new FileInputStream(f));
synthesizer.loadAllInstruments(soundbank);
synthesizer.open();
p("\n now loaded on synthesizer: ");
printInstruments(soundbank,synthesizer.getLoadedInstruments());
}
else {
p(filename + " not found");
System.exit(0);
}
}catch(Exception e){
e.printStackTrace();
}
}
private static void printInstruments(Soundbank soundbank,Instrument[] instruments){
p("");
p("----------------------------------------------------------------------------");
p("Soundbank name: " + soundbank.getName());
p("Soundbank version: " + soundbank.getVersion());
p("Description: " + soundbank.getDescription());
p("Author: " + soundbank.getVendor() + ".");
p("Number of instruments: " + soundbank.getInstruments().length);
for (Instrument i : instruments)
{
p( "Bank=" + i.getPatch().getBank() +
" Patch=" + i.getPatch().getProgram() +
" Instr.=" + i);
}
}
public static void p(Object o){
System.out.println(o);
}
}
在命令提示符输出:
C:\ Javapro> javac -classpath gervill.jar; jfugue-4.0.3.jar SF2Test2.java
C:\ Javapro> java -classpath gervill.jar; jfugue-4.0.3.jar;。 SF2Test2
现在加载到合成器上:
