バイト配列への複合

[syntaro]

すいません。
教えてください。

OnMidiInputEventListener2をつくって、バイト配列に 復号しようとしているのですが、
最後のRPNとNRPのところ、7ビットか14ビットか判定できないので、複合できません。
パラメータに7ビットか14ビットか教えるものが欲しいです。

これであっているか、教えていただけますと幸いです。

そのあと以下のようにしました。

OnMidiInputEventListener.java追加 boolean isRequestDataentryValue();
OnMidiInputEventListener2.java追加 boolean isRequestDataentryValue() { return false; }
パーサーのほうで、このフラグをみて、CCとするか、あるいはRPN/NRPNとするか、選ぶ処理を入れました。

こちらもよろしければ、参考になればさいわいです。

私のあてたパッチを暫定的にアップロードしました。

まだまだ伸びしろはありますが、
