如何在Midi中更换乐器?
在显示“ Channel out of range”(通道超出范围)后,我可以将channel的值最多更改为9,这全是钢琴。例如,如何将其更改为吉他
public noteplay()
throws InvalidMidiDataException,MidiUnavailableException
{
bpm =80;
beatLength = 1;
theTimeMelody = 0;
theTimeBass =0;
seq = new Sequence(Sequence.PPQ,3);
trkBass = seq.createTrack();
trkMelody = seq.createTrack();
}
public void melody(int volume)
throws InvalidMidiDataException,MidiUnavailableException
{
int list1[] = { 56,59,60,63,56,59,60,63, 61,64,65,68,61,64,65,68, 56,59,60,63,56,59,60,63, 63,66,67,70,73,66,67,70,};
for (int pitch : list1)
{
ShortMessage onMsg = new ShortMessage();
onMsg.setMessage(ShortMessage.NOTE_ON, 0, pitch, 80);
ShortMessage offMsg = new ShortMessage();
offMsg.setMessage(ShortMessage.NOTE_OFF, 0, pitch, 90);
trkBass.add(new MidiEvent(onMsg,theTimeBass));
trkBass.add(new MidiEvent(offMsg,theTimeBass+beatLength));
theTimeBass += beatLength;
}
}
}
最佳答案
通用MIDI标准为鼓保留了第十个通道。
您可以将其他十五个通道用于旋律乐器。
