Question

我尝试使用MIDI事件BASS.NET创建和播放，但它播放不正常（没声音），想要帮助，谢谢你们！ [来自Google的翻译]

public void build_MIDI() {
        BASS_MIDI_EVENT[] events ={
         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_TEMPO, 500000, 0, 0,0),
         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_PROGRAM, 1, 0, 0,0),
         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_NOTE, 60, 100, 0,0), 
         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_END, 0, 0, 0,0),
        };

        int build_play_midi_steam = BassMidi.BASS_MIDI_StreamCreateEvents(events,96, BASSFlag.BASS_SAMPLE_LOOP, 0);
        Bass.BASS_ChannelPlay(build_play_midi_steam, false);
    }

我已经解决了这个问题，代码演示了在steamEvent中播放的两个音符。如果你想获得有关API推荐阅读的更多信息

public void build_MIDI()
    {
        BASS_MIDI_EVENT[] events ={
         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_TEMPO, 500000, 0, 0,0),
         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_PROGRAM, 0, 0, 0,0),

         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_NOTE, MAKEWORD(91,100), 0, 0 ,0),
            new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_NOTE, MAKEWORD(60,100), 0, 0 ,0),
            new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_NOTE, 91, 0, 48,0 ),
            new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_NOTE, 60, 0, 96,0 ),
         new BASS_MIDI_EVENT(BASSMIDIEvent.MIDI_EVENT_END, 0, 0, 2000,0),
        };

        int build_play_midi_steam = BassMidi.BASS_MIDI_StreamCreateEvents(events,100, BASSFlag.BASS_MIDI_DECAYEND | BASSFlag.BASS_MIDI_DECAYSEEK | BASSFlag.BASS_MIDI_NOFX, 1);

        Bass.BASS_ChannelPlay(build_play_midi_steam, false);

    }
    ushort MAKEWORD(byte a, byte b)
    {
        return (ushort)(a | (b << 8));
    }

使用BASS.NET创建MIDI事件没有声音
