プログラミングやコンピュータに関する事はあまり詳しくないため、多少わかりにくい文章になっているかも知れませんが、質問させて下さい。
バイナリデータをpoke命令で変数に記録したのですが、最後、無駄にヌルが入ってしまいます。
このヌルを消すには、どうすれば良いでしょうか。お願いします。

一行目は数字の個数、二行目は音の鳴らし方です。
自然数は音を鳴らし、-1は音を鳴らすのをやめ、0は何もしないとなっています。
自然数の意味は次の通りです。
1:ミ
2:低ラ
3:低シ
4:ド
5:ミ
6:ファ
7:ラ
8:シ
9:高ド
10:高ミ
11:高ファ
12:高ラ
13:高シ
+13:半音上げる
+26:全音上げる

これを実行してMIDIファイルを作ると、なぜか最後にヌルが連続します。
なので、どうすればヌルを消せるか、どなたか教えて下さい。お願いします。

無駄が多いような気もしますが、とりあえず

>>bsave "aaa.mid",mdata

のパラメーターをきちんと指定しましょう。

実行してMIDIファイルを作成したのですが、再生出来ません。
どうすれば再生出来るか、御存知でしたら教えて下さい。

確かに…
二度同じ事を繰り返している箇所は消したつもりだったのですが、一部が残っていたみたいです。

>>どうすれば再生出来るか、御存知でしたら教えて下さい。

フォーマット理解してバイナリレベルで操作しているんだから、出来た
ファイルを解析すれば解決するかと思うよ?

それに「再生出来ません」じゃ、何も伝わらないよ。
