## 🎶簡単な使い方
```CSharp
using SoundMaker;
using SoundMaker.Sounds;
using SoundMaker.Sounds.Score;
using SoundMaker.Sounds.SoundChannels;
using SoundMaker.WaveFile;

        var rightChannel = new SquareSoundChannel(tempo, format, SquareWaveRatio.Point25, PanType.Right)
        {
            // ISoundComponentを実装したクラスのオブジェクトをチャンネルに追加していく。
            // 現段階では普通の音符、休符、タイ、連符を使うことができる。

            new Tie(new Note(Scale.D, 5, LengthType.Eighth), LengthType.Eighth),
            new Tuplet(GetComponents(), LengthType.Quarter)
        };
        var rightChannel2 = new SquareSoundChannel(tempo, format, SquareWaveRatio.Point125, PanType.Right)
        {
            new Note(Scale.C, 4, LengthType.Eighth, isDotted: true),
            new Note(Scale.D, 4, LengthType.Quarter),
            new Rest(LengthType.Quarter)

            new Note(Scale.D, 3, LengthType.Quarter),
            new Rest(LengthType.Quarter)
        };

var channels = new List<ISoundChannel>() { rightChannel, rightChannel2, leftChannel };
        // ミックスは'StereoMixer'クラスで行う。 
        return new StereoMixer(channels).Mix();
    }

private static IReadOnlyList<BasicSoundComponentBase> GetComponents()
    {
        return new List<BasicSoundComponentBase>()
        {
            new Note(Scale.E, 5, LengthType.Eighth),
            new Note(Scale.F, 5, LengthType.Eighth),
            new Note(Scale.G, 5, LengthType.Eighth),
        };
    }
