midifile

中間：C ++ MIDI文件解析庫

Midifile是用於讀取/編寫標準MIDI文件的C ++類的庫。該圖書館由6個課程組成：

中間	處理MIDI文件的主要接口。中間級別顯示為中世紀的二維數組：第一個維度是曲目列表，第二維是中世紀的列表。
MidieventList	管理MIDI文件軌道中的中世紀列表的數據結構。
中世紀	中段的主要存儲單元。該類由tick時間戳（三角洲或絕對）和MIDI消息字節（或標準MIDI文件元消息）組成。
中等大事	中世紀的基礎。這是代表MIDI（或元）消息的未簽名字節的STL向量。
Binasc	用於中間的助手類，允許以ASCII格式讀取/寫作MIDI文件，描述了二進制標準MIDI文件的字節。
選項	示例程序中用於解析命令行選項的可選便利類。可以從庫中刪除此類，因為使用中間類別不需要。

這是一個示意圖的示意圖：類別如何使用：

MidiFile類包含一個存儲在MidiEventList對像中的軌道。 MidiEventList本身就是MidiEvent S的向量，該向量將每個MIDI活動存儲在賽道上。 MidiEvent S包含一個時間戳和一個MidiMessage ，它是無符號字符值的向量，存儲了MIDI消息（或Meta-Message）的原始字節。

文檔正在http://midifile.sapp.org上構建。下面給出了用於閱讀和寫入MIDI文件的基本示例。

下載

您可以從中間圖庫的github頁面下載為zip文件，或者如果使用git，請使用此命令下載：

git clone https://github.com/craigsapp/midifile

這將創建具有庫的源代碼的midifile目錄。

用GCC編譯

可以用命令編譯該庫：

make library

這將創建文件lib/libmidifile.a ，可用於鏈接到使用庫的程序。示例程序可以用命令編譯：

make programs

這將在工具目錄中編譯所有示例程序。編譯的示例程序將存儲在bin目錄中。要同時編譯庫和示例程序一步，請鍵入：

make

僅編譯一個單個程序，例如createmidifile ，類型：

make createmidifile

您還可以將自己的程序放在tools中，例如myprogram.cpp和編譯類型：

make myprogram

編譯的程序將是bin/myprogram 。

在您自己的項目中使用

使用您自己項目中的中間庫的最簡單方法是將標題文件複製到include目錄中的標題文件和src目錄中的源代碼文件中的標題文件中。您不需要復制Options.h或Options.cpp ，因為MidiFile類不取決於它們。 Github上的Verovio和Midiroll項目都使用此方法使用中間圖庫。另外，您可以分配中間存儲庫，並構建源代碼的編譯庫文件，該文件可以在項目中使用include目錄內容複製。

MIDI文件閱讀示例

以下程序列出了MIDI文件中的所有中世紀。該程序在每個曲目上迭代，打印曲目中所有MIDI事件的列表。對於每個事件，都會給出MIDI消息的性能時間的絕對tick時間戳，然後將消息本身作為十六進製字節列表。

您可以根據文件中的任何節奏meta-messages（如果沒有tempo meta-messages，則使用默認的默認節奏，每分鐘，使用默認的tempo tempo，將絕對的滴答時間戳轉換為幾MidiFile::doTimeAnalysis() 。事件的絕對啟動時間顯示在程序輸出的第二列中。

MidiFile::linkNotePairs()函數可用於匹配筆記和記錄。完成此操作後，您可以使用Note-On消息的MidiEvent::getDurationInSeconds()訪問註釋的持續時間。音符持續時間顯示在程序輸出的第三列中。

請注意，中間庫類在smf名稱空間中，因此using namespace smf;或smf::訪問課程需要前綴。

# include " MidiFile.h "
# include " Options.h "
# include < iostream >
# include < iomanip >

using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   Options options;
   options. process (argc, argv);
   MidiFile midifile;
   if (options. getArgCount () == 0 ) midifile. read (cin);
   else midifile. read (options. getArg ( 1 ));
   midifile. doTimeAnalysis ();
   midifile. linkNotePairs ();

   int tracks = midifile. getTrackCount ();
   cout << " TPQ: " << midifile. getTicksPerQuarterNote () << endl;
   if (tracks > 1 ) cout << " TRACKS: " << tracks << endl;
   for ( int track= 0 ; track<tracks; track++) {
      if (tracks > 1 ) cout << " n Track " << track << endl;
      cout << " Tick t Seconds t Dur t Message " << endl;
      for ( int event= 0 ; event<midifile[track]. size (); event++) {
         cout << dec << midifile[track][event]. tick ;
         cout << ' t ' << dec << midifile[track][event]. seconds ;
         cout << ' t ' ;
         if (midifile[track][event]. isNoteOn ())
            cout << midifile[track][event]. getDurationInSeconds ();
         cout << ' t ' << hex;
         for ( int i= 0 ; i<midifile[track][event]. size (); i++)
            cout << ( int )midifile[track][event][i] << ' ' ;
         cout << endl;
      }
   }

   return 0 ;
}

上面的示例程序將讀取其在命令行中找到的第一個文件名，或者如果找不到參數，則將從標準輸入中讀取。 MIDI文件的二進制標準MIDI文件和ASCII表示形式都可以輸入程序中。例如，將以下文本保存到稱為twinkle.txt的文件中以用作輸入數據。該內容代表標準MIDI文件的十六進製字節，該文件將自動通過MidiFile類解析。

MidiFile類的默認行為是存儲以MidiEvent::tick可用的MIDI事件的絕對tick時間，這是從文件開始到當前事件的tick時間。在標準MIDI文件中，tick存儲為DELTA值，其中tick表示自曲目中的上一條消息以來等待的持續時間。要訪問Delta tick值，您可以（1）從列表中的上一個刻度時間徵用當前刻度時間，也可以將MidiFile::makeDeltaTime()調用以將絕對tick值轉換為delta tick值。

MidiFile::joinTracks()函數可用於將多軌數據轉換為單個時間序列。可以通過調用MidiFile::splitTracks()函數來逆轉joinTrack()操作。這是一個程序示例，將MidiEvents加入單個軌道，以便可以單個循環處理數據：

# include " MidiFile.h "
# include " Options.h "
# include < iostream >
# include < iomanip >

using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   Options options;
   options. process (argc, argv);
   MidiFile midifile;
   if (options. getArgCount () > 0 ) midifile. read (options. getArg ( 1 ));
   else midifile. read (cin);
   cout << " TPQ: " << midifile. getTicksPerQuarterNote () << endl;
   cout << " TRACKS: " << midifile. getTrackCount () << endl;
   midifile. joinTracks ();
   // midifile.getTrackCount() will now return "1", but original
   // track assignments can be seen in .track field of MidiEvent.
   cout << " TICK    DELTA   TRACK   MIDI MESSAGE n " ;
   cout << " ____________________________________ n " ;
   MidiEvent* mev;
   int deltatick;
   for ( int event= 0 ; event < midifile[ 0 ]. size (); event++) {
      mev = &midifile[ 0 ][event];
      if (event == 0 ) deltatick = mev-> tick ;
      else deltatick = mev-> tick - midifile[ 0 ][event- 1 ]. tick ;
      cout << dec << mev-> tick ;
      cout << ' t ' << deltatick;
      cout << ' t ' << mev-> track ;
      cout << ' t ' << hex;
      for ( int i= 0 ; i < mev-> size (); i++)
         cout << ( int )(*mev)[i] << ' ' ;
      cout << endl;
   }
   return 0 ;
}

以下是新的單軌輸出。第一列是消息的絕對tick時間戳；第二列是增量tick值；第三列是原始軌道值；最後一列包含MIDI消息（在十六進製字節中）。

MIDI文件寫作示例

以下是創建MIDI文件的示例程序。該程序將生成一個隨機的音符序列，並將其附加到軌道的末尾。默認情況下， MidiFile對象包含一個軌道，除非添加更多軌道，否則將寫入Type-0 MIDI文件。在曲目中添加註釋後，必須將其分類為“時間順序”，然後再將其寫入文件。

# include " MidiFile.h "
# include " Options.h "
# include < random >
# include < iostream >

using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   Options options;
   options. define ( " n|note-count=i:10 " , " How many notes to randomly play " );
   options. define ( " o|output-file=s " ,   " Output filename (stdout if none) " );
   options. define ( " i|instrument=i:0 " ,  " General MIDI instrument number " );
   options. define ( " x|hex=b " ,           " Hex byte-code output " );
   options. process (argc, argv);

   random_device rd;
   mt19937 mt ( rd ());
   uniform_int_distribution< int > starttime ( 0 , 100 );
   uniform_int_distribution< int > duration ( 1 , 8 );
   uniform_int_distribution< int > pitch ( 36 , 84 );
   uniform_int_distribution< int > velocity ( 40 , 100 );

   MidiFile midifile;
   int track   = 0 ;
   int channel = 0 ;
   int instr   = options. getInteger ( " instrument " );
   midifile. addTimbre (track, 0 , channel, instr);

   int tpq     = midifile. getTPQ ();
   int count   = options. getInteger ( " note-count " );
   for ( int i= 0 ; i<count; i++) {
      int starttick = int ( starttime (mt) / 4.0 * tpq);
      int key       = pitch (mt);
      int endtick   = starttick + int ( duration (mt) / 4.0 * tpq);
      midifile. addNoteOn (track, starttick, channel, key, velocity (mt));
      midifile. addNoteOff (track, endtick,   channel, key);
   }
   midifile. sortTracks ();  // Need to sort tracks since added events are
                           // appended to track in random tick order.
   string filename = options. getString ( " output-file " );
   if (filename. empty ()) {
      if (options. getBoolean ( " hex " )) midifile. writeHex (cout);
      else cout << midifile;
   } else
      midifile. write (filename);

   return 0 ;
}

如果未指定輸出文件，則MIDI文件內容將以BINASC格式打印到標準輸出，可以將其重新讀取到Midifile對像中並轉換為標準MIDI文件（有關如何執行此操作，請參閱頁面下方的讀/寫示例）：

讀/寫示例

這是一個示例最小程序，將上述六角字節代碼轉換為標準MIDI文件：

# include " MidiFile.h "
# include < iostream >

using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   if (argc != 3 ) return 1 ;
   MidiFile midifile;
   midifile. read (argv[ 1 ]);
   if (midifile. status ()) midifile. write (argv[ 2 ]);
   else cerr << " Problem reading MIDI file " << argv[ 1 ] << endl;
}

MidiFile::read()函數將自動識別輸入是二進制標準MIDI文件，十六進製字節代碼表示或廣義的Binasc語法文件（其中包括字節代碼）。讀取MIDI文件後，可以檢查MidiFile::status()函數，以確定是否沒有問題讀取文件。

如何處理多個輸入文件並獲取MIDI文件的持續時間

此示例使用MidiFile::getFileDurationInSeconds()來計算MIDI文件的持續時間。另外，此示例顯示了使用選項類時如何處理多個輸入文件。

# include " MidiFile.h "
# include " Options.h "
# include < iostream >
using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   Options options;
   options. process (argc, argv);
   MidiFile midifile;
   if (options. getArgCount () == 0 ) {
      midifile. read (cin);
      cout << midifile. getFileDurationInSeconds () << " seconds " << endl;
   } else {
      int count = options. getArgCount ();
      for ( int i= 0 ; i<count; i++) {
         string filename = options. getArg (i+ 1 );
         if (count > 1 ) cout << filename << " t " ;
         midifile. read (filename);
         cout << midifile. getFileDurationInSeconds () << " seconds " << endl;
      }
   }
   return 0 ;
}

如何從MIDI文件中提取文本元信息。

如果消息是文本元消息， MidiMessage::isText()函數將返回true。以下程序將所有軌道合併到一個列表中，並進行一個循環檢查文本元信息，並在發現時將其打印出來。 MidiMessage::getMetaContent()函數從RAW MIDI文件字節中提取消息的文本字符串。

# include " MidiFile.h "
# include < iostream >

using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   MidiFile midifile;
   if (argc == 1 ) midifile. read (cin);
   else midifile. read (argv[ 1 ]);
   if (!midifile. status ()) {
      cerr << " Problem reading MIDI file " << endl;
      return 1 ;
   }

   midifile. joinTracks ();
   for ( int i= 0 ; i<midifile[ 0 ]. getEventCount (); i++) {
      if (midifile[ 0 ][i]. isText ()) {
         string content = midifile[ 0 ][i]. getMetaContent ();
         cout << content << endl;
      }
   }

   return 0 ;
}

通過使用.isLyricText()而不是.isText()提取歌詞相同，並且由.isTrackName()識別軌道名稱元信息。

如何將1型MIDI文件轉換為0型MIDI文件

這是將多軌MIDI文件轉換為單軌MIDI文件的演示：

# include " MidiFile.h "
# include < iostream >
using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   if (argc != 3 ) {
      cerr << " Usage: " << argv[ 0 ] << " input output " << endl;
      return 1 ;
   }
   MidiFile midifile;
   midifile. read (argv[ 1 ]);
   if (!midifile. status ()) {
      cerr << " Problem reading MIDI file " << endl;
      return 1 ;
   }

   midifile. joinTracks ();
   midifile. write (argv[ 2 ]);

   return 0 ;
}

.joinTracks()函數將所有軌道合併為單個軌道。而且，如果MidiFile對像在編寫時只有一個軌道，則將其編寫為type-0（單軌）MIDI文件。

如何在MIDI文件中檢查鼓軌

在一般的MIDI文件中，鼓軌道在第10個頻道上，該通道由整數9表示。以下示例搜索每個軌道中的MIDI事件，直到在頻道9上找到註釋：

# include " MidiFile.h "
# include < iostream >
using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   MidiFile midifile;
   if (argc == 1 ) midifile. read (cin);
   else midifile. read (argv[ 1 ]);
   if (!midifile. status ()) {
      cerr << " Problem reading MIDI file " << endl;
      return 1 ;
   }

   bool found = false ;
   for ( int i= 0 ; i<midifile. getTrackCount (); i++) {
      for ( int j= 0 ; j<midifile[i]. getEventCount (); j++) {
         if (midifile[i][j]. isNote ()) {
            int channel = midifile[i][j]. getChannelNibble ();
            if (channel == 9 ) {
               found = true ;
               break ;
            }
         }
      }
      if (found == true ) break ;
   }
   if (found) cout << " Has a percussion part. " << endl;
   else cout << " Does not have a percussion part. " << endl;

   return 0 ;
}

如何在MIDI文件中刪除打擊樂筆記

對於某些音樂分析應用程序，從MIDI文件中刪除打擊樂筆記很有用。這是一個中間圖庫如何完成的示例。

# include " MidiFile.h "
# include < iostream >
using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   if (argc != 3 ) {
      cerr << " Usage: " << argv[ 0 ] << " input output " << endl;
      return 1 ;
   }
   MidiFile midifile;
   midifile. read (argv[ 1 ]);
   if (!midifile. status ()) {
      cerr << " Problem reading MIDI file " << endl;
      return 1 ;
   }

   for ( int i= 0 ; i<midifile. getTrackCount (); i++) {
      for ( int j= 0 ; j<midifile[i]. getEventCount (); j++) {
         if (midifile[i][j]. isNote ()) {
            int channel = midifile[i][j]. getChannelNibble ();
            if (channel == 9 ) {
               midifile[i][j]. clear ();
            }
         }
      }
   }

   midifile. removeEmpties ();  // optional
   midifile. write (argv[ 2 ]);
   return 0 ;
}

要刪除MIDI消息，請清除其向量基類。這將在軌道上留下空的MidiEvent ，但是MidiFile::write()函數將忽略任何空的MidiMessage信息。可以調用MidiFile::removeEmpties()函數，以明確從軌道上刪除任何空中MidiEvents 。

如何在MIDI文件中轉動音調

此示例顯示瞭如何在MIDI文件中轉置註釋。應該注意避免在MIDI中換頻道10，因為這是為鼓軌道保留的（大多數MIDI文件都使用一般的MIDI大會）。

# include " MidiFile.h "
# include " Options.h "
# include < iostream >

using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   Options options;
   options. define ( " t|transpose=i:0 " , " Semitones to transpose by " );
   options. process (argc, argv);

   MidiFile midifile;
   if (options. getArgCount () == 0 ) midifile. read (cin);
   else midifile. read (options. getArg ( 1 ));
   if (!midifile. status ()) {
      cerr << " Could not read MIDI file " << endl;
      return 1 ;
   }

   int transpose = options. getInteger ( " transpose " );
   for ( int i= 0 ; i<midifile. getTrackCount (); i++) {
      for ( int j= 0 ; j<midifile[i]. getEventCount (); j++) {
         if (!midifile[i][j]. isNote ()) continue ;
         if (midifile[i][j]. getChannel () == 9 ) continue ;
         int newkey = transpose + midifile[i][j]. getP1 ();
         midifile[i][j]. setP1 (newkey);
      }
   }

   if (options. getArgCount () < 2 ) cout << midifile;
   else midifile. write (options. getArg ( 2 ));
   return 0 ;
}

如何列出MIDI文件中使用的儀器號碼

以下示例列出了MIDI文件中使用的所有儀器號。它沒有分析鼓軌道。

# include " MidiFile.h "
# include " Options.h "
# include < set >
# include < utility >
# include < iostream >

using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   Options options;
   options. process (argc, argv);
   MidiFile midifile;
   if (options. getArgCount () == 0 ) midifile. read (cin);
   else midifile. read (options. getArg ( 1 ));
   if (!midifile. status ()) {
      cerr << " Could not read MIDI file " << endl;
      return 1 ;
   }

   pair< int , int > trackinst;
   set<pair< int , int >> iset;
   for ( int i= 0 ; i<midifile. getTrackCount (); i++) {
      for ( int j= 0 ; j<midifile[i]. getEventCount (); j++) {
         if (midifile[i][j]. isTimbre ()) {
            trackinst. first = i;
            trackinst. second = midifile[i][j]. getP1 ();
            iset. insert (trackinst);
         }
      }
   }
   for ( auto it : iset)
      cout << " Track: " << it. first << " t Instrument: " << it. second << endl;
   return 0 ;
}

如何模仿MIDI文件中的氣質

如果您想在沒有專門了解氣質的合成器中模擬標準MIDI文件中的氣質，那麼此示例很有用。每個音高級都放入單獨的軌道和MIDI通道中。然後將一個音調消息添加到每個通道中每個軌道的開始中以控制氣質。注意避免使用MIDI頻道10，該頻道保留給MIDI的打擊樂音色。

# include " MidiFile.h "
# include < iostream >
using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   if (argc != 3 ) {
      cerr << " Usage: " << argv[ 0 ] << " input output " << endl;
      return 1 ;
   }
   MidiFile midifile;
   midifile. read (argv[ 1 ]);
   if (!midifile. status ()) {
      cerr << " Problem reading MIDI file " << endl;
      return 1 ;
   }

   midifile. joinTracks ();
   for ( int i= 0 ; i<midifile[ 0 ]. getEventCount (); i++) {
      midifile[ 0 ][i]. seq = 2 ;
      if (!midifile[ 0 ][i]. isNote ()) {
         midifile[ 0 ][i]. track = 0 ;
         continue ;
      }
      int pc = midifile[ 0 ][i]. getP1 () % 12 ;
      int channel = midifile[ 0 ][i]. getChannelNibble ();
      if (channel != 9 ) {
         midifile[ 0 ][i]. track = pc + 1 ;
         if (pc >= 9 ) pc++;
         midifile[ 0 ][i]. setChannelNibble (pc);
      } else midifile[ 0 ][i]. track = 13 ;
   }
   midifile. splitTracks ();

   double maxbend = 200.0 ;  // typical pitch-bend depth in cents on synthesizers
   // pythagorean tuning deviations from equal temperament in cents.
   vector< double > pythagorean = {- 3.91 , 9.78 , 0.00 , - 9.78 , 3.91 , - 5.87 , 7.82 ,
         - 1.96 , - 11.73 , 1.96 , - 7.82 , 5.87 };

   for ( int i= 0 ; i< 12 ; i++) {
      int maxtrack = midifile. getTrackCount ();
      int track = i+ 1 ;
      if (track >= maxtrack) break ;
      int channel = i;
      if (i >= 9 ) channel++;
      double bend = pythagorean[i] / maxbend;
      MidiEvent* me = midifile. addPitchBend (track, 0 , channel, bend);
      me-> seq = 1 ;
   }

   midifile. sortTracks ();
   midifile. write (argv[ 2 ]);

   return 0 ;
}

MidiFile::splitTracks()函數將生成13或14個軌道。軌道0將包含來自原始文件的所有非音符MIDI消息，而軌道1至12將包含MIDI通道上1-12的特定音調類的音符，跳過通道10（一般的MIDI打擊樂通道）。打擊樂筆記將放在軌道13中，但保留在第10頻道上。

在程序中使用中MidiEvent::seq將其設置為1和2的使用，以強制在滴答時間0中施加第一個音符在插頭彎曲消息在同一時間戳插入後放置的第一個音符，如果將MidiFile::sortTracks() （如果將較低序列編號的事件（如果將較低序列編號）放置在軌道中，則將序列編號較低的事件放置在軌道中，將其放置在軌道中的賽道中）。無論如何，彎曲式消息可能會在音符之前進行排序，但是使用seq應保證將其放置在第一筆記之前。

在巴赫（Bach）脾氣暴躁的克拉維爾（Clavier）上嘗試此程序，第一本書，fugue in c-sharp Minor：

如何將MIDI軌道分為單獨的MIDI文件

以下程序將帶有三個或三個或更多軌道的多軌MIDI文件，然後將每個軌道分為單獨的MIDI文件。原始MIDI文件的表達軌道被複製到新的MIDI文件的0軌道中，並將第一個MIDI文件的單個軌道複製到輸出MIDI文件的第一個軌道。

# include " MidiFile.h "
# include < iostream >
# include < vector >
using namespace std ;
using namespace smf ;

int main ( int argc, char ** argv) {
   if (argc != 3 ) {
      cerr << " Usage: " << argv[ 0 ] << " input output " << endl;
      return 1 ;
   }
   MidiFile midifile (argv[ 1 ]);
   if (!midifile. status ()) {
      cerr << " Problem reading input " << endl;
      return 1 ;
   }
   if (midifile. getTrackCount () < 3 ) {
      cerr << " Not enough tracks to split " << endl;
      return 1 ;
   }
   string basename = argv[ 2 ];
   if (basename. substr (basename. size () - 4 ) == " .mid " )
      basename = basename. substr ( 0 , basename. size () - 4 );
   int outcount = midifile. getTrackCount () - 1 ;
   vector<MidiFile> outputs (outcount);
   for ( int i= 0 ; i<outcount; i++) {
      outputs[i]. addTrack ();
      for ( int j= 0 ; j<midifile[ 0 ]. getEventCount (); j++)
         outputs[i]. addEvent (midifile[ 0 ][j]);
      for ( int j= 0 ; j<midifile[i+ 1 ]. getEventCount (); j++)
         outputs[i]. addEvent ( 1 , midifile[i+ 1 ][j]);
   }
   for ( int i= 0 ; i<outcount; i++)
      outputs[i]. write (basename + " - " + to_string (i+ 1 ) + " .mid " );
   return 0 ;
}

這是從MIDI文件輸入中提取的第一個文件，以示例：

如何在MIDI文件中使用彎曲消息創建顫音

該示例演示了在MIDI文件（在特定通道上）中的音符的常數顫音的生成。該程序在文件末尾增加了一個額外的軌道，以存儲音高彎曲。無論MIDI文件的速度設置如何，顫音速率都是恆定的，因為顫音是在物理時間而不是tick時間計算的。 MidiFile::getAbsoluteTickTime()函數計算了MIDI文件中的物理時間和tick時間之間的轉換。

該程序演示瞭如何在MIDI標題中設置每季度的音符值。在這種情況下，將其設置為a*b的因子，即一個週期的持續時間（因此每個週期都有四分之一音符的持續時間）。還根據周期的所需持續時間計算節奏元消息。

例如，嘗試選項-a 3 -b 4 -c 200 -d 1 -o 3x4.mid ，它將在每個週期持續1秒的情況下播放3個against -4模式。或以下是100個循環的11- against -13： -a 11 -b 13 -c 100 -d 5 -o 11x13.mid 。
