java - Mac 上的 JFugue 5 外部 MIDI 设备

Question

我正在尝试连接我的 PSR-A3000 键盘以从计算机播放一些 MIDI 文件。当我运行代码时：

import java.io.File;
import java.io.IOException;
import javax.sound.midi.InvalidMidiDataException;
import javax.sound.midi.MidiSystem;
import javax.sound.midi.Sequence;


public class jFugeFilePlayer {



    public static void main(String args[]) {
        DeviceThatWillReceiveMidi device = null;
        device = new DeviceThatWillReceiveMidi(); // handle MIDI Unavailable Exception
        Sequence sequence = null;

        try {
            sequence = MidiSystem.getSequence(new File("/Users/path.../baharanMelody.midi"));
        } catch (InvalidMidiDataException e) {
            // handle Invalid MIDI Data Exception
        } catch (IOException e) {
            // handle IO Exception
            e.printStackTrace();
        }
        device.setSequence(sequence);

    }
}

我看到这里的帖子有类似的问题，并且不能超越“device.sendSequence”上的另一个异常。 JFugue 5 外接 MIDI 设备

我得到错误：

BUILD FAILURE

我试过 javaxsound.midi.MidiSystem 并且它确认我的设备工作正常。我添加了堆栈跟踪以查看是否可以提供帮助。

请问我做错了什么？

任何帮助将不胜感激。
