midifile
1.0.0
Midifile adalah perpustakaan kelas C ++ untuk membaca/menulis file MIDI standar. Perpustakaan terdiri dari 6 kelas:
| Midifile | Antarmuka utama untuk menangani file MIDI. Kelas menengah muncul sebagai array dua dimensi mideven: dimensi pertama adalah daftar trek, dan dimensi kedua adalah daftar mideven. |
| Daftar Midievent | Struktur data yang mengelola daftar mideven untuk trek file MIDI. |
| Pertengahan | Unit penyimpanan utama untuk midimessages di midifile. Kelas terdiri dari centang timestamp (delta atau absolute) dan vektor byte pesan midi (atau pesan meta file midi standar). |
| Midimessage | Kelas dasar untuk mideven. Ini adalah vektor STL byte unsigned yang mewakili pesan MIDI (atau meta). |
| Binasc | Kelas helper untuk midifile yang memungkinkan membaca/menulis file MIDI dalam format ASCII yang menggambarkan byte file MIDI standar biner. |
| Opsi | Kelas kenyamanan opsional yang digunakan untuk parsing opsi baris perintah dalam program contoh. Kelas ini dapat dihapus dari perpustakaan karena tidak diperlukan untuk menggunakan kelas menengah. |
Berikut adalah skema bagaimana kelas digunakan bersama:
Kelas MidiFile berisi vektor trek yang disimpan di objek MidiEventList . MidiEventList sendiri merupakan vektor MidiEvent S, yang menyimpan setiap acara MIDI di trek. S MidiEvent berisi cap waktu dan MidiMessage yang merupakan vektor nilai char yang tidak ditandatangani, menyimpan byte mentah dari pesan MIDI (atau meta-message).
Dokumentasi sedang dibangun di http://midifile.sapp.org. Contoh penting untuk membaca dan menulis file MIDI diberikan di bawah ini.
Anda dapat mengunduh sebagai file zip dari halaman GitHub untuk perpustakaan midifile, atau jika Anda menggunakan git, lalu unduh dengan perintah ini:
git clone https://github.com/craigsapp/midifile Ini akan membuat direktori midifile dengan kode sumber untuk perpustakaan.
Perpustakaan dapat dikompilasi dengan perintah:
make library Ini akan membuat file lib/libmidifile.a yang dapat digunakan untuk menautkan ke program yang menggunakan perpustakaan. Contoh program dapat dikompilasi dengan perintah:
make programs Ini akan menyusun semua contoh program dalam direktori Alat. Program contoh yang dikompilasi akan disimpan di direktori bin . Untuk mengkompilasi baik perpustakaan dan contoh program semuanya dalam satu langkah, ketik:
make Untuk mengkompilasi hanya satu program, seperti createmidifile , ketik:
make createmidifile Anda juga dapat menempatkan program Anda sendiri di tools , seperti myprogram.cpp dan untuk mengkompilasi tipe:
make myprogram Program yang dikompilasi adalah bin/myprogram .
Cara termudah untuk menggunakan pustaka midifile dalam proyek Anda sendiri adalah dengan menyalin file header di direktori include dan file kode sumber di direktori src ke dalam proyek Anda sendiri. Anda tidak perlu menyalin Options.h atau Options.cpp karena kelas MidiFile tidak bergantung padanya. Proyek Verovio dan Midiroll di GitHub keduanya menggunakan metode ini untuk menggunakan pustaka midifile. Atau, Anda dapat membayar repositori midifile dan membangun file pustaka yang dikompilasi dari kode sumber yang dapat disalin dengan konten direktori include dalam proyek Anda.
Program berikut ini mencantumkan semua mideven dalam file MIDI. Program ini mengulangi setiap trek, mencetak daftar semua acara MIDI di trek. Untuk setiap acara, centang centang absolut untuk waktu kinerja pesan MIDI diberikan, diikuti oleh pesan itu sendiri sebagai daftar byte hex.
Anda dapat menjalankan fungsi MidiFile::doTimeAnalysis() untuk mengubah centang centang absolut menjadi detik, menurut setiap pesan meta tempo dalam file (menggunakan tempo default 120 kuartal not per menit jika tidak ada meta-mess Tempo). Waktu awal absolut dari acara ini ditampilkan di kolom kedua dari output program.
Fungsi MidiFile::linkNotePairs() dapat digunakan untuk mencocokkan note-ons dan not-off. Ketika ini selesai, Anda dapat mengakses durasi catatan dengan MidiEvent::getDurationInSeconds() untuk pesan note-on. Durasi catatan ditampilkan di kolom ketiga output program.
Perhatikan bahwa kelas perpustakaan menengah berada di namespace smf , jadi using namespace smf; atau smf:: Prefiks diperlukan untuk mengakses kelas.
# include " MidiFile.h "
# include " Options.h "

# 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;

cout << ( int )midifile[track][event][i] << ' ' ;
cout << endl;
}
}
return 0 ;
} Contoh program di atas akan membaca nama file pertama yang ditemukan pada baris perintah, atau akan dibaca dari input standar jika tidak ada argumen yang ditemukan. Baik file MIDI standar biner dan representasi file MIDI AS ASCII dapat dimasukkan ke dalam program. Misalnya, simpan teks berikut ke dalam file yang disebut twinkle.txt untuk digunakan sebagai data input. Konten ini mewakili byte hex untuk file midi standar, yang secara otomatis akan diuraikan oleh kelas MidiFile .

Di bawah ini adalah output dari contoh program yang diberikan data input di atas. Nilai TPQ adalah nilai kutu-per-kuartal dari header MIDI. Dalam contoh ini, setiap not kuartal memiliki durasi 120 kutu file MIDI. File MIDI di atas berisi tiga trek, dengan trek pertama (trek ekspresi, tidak memiliki konten selain pesan meta akhir-track, ff 2f 00 dalam byte hex. Lagu kedua dimulai dengan pesan note-on midi 90 48 40 (dalam hex) yang akan mulai bermain midi note 72 (c pitch satu oktaf di atas c) dengan bakat menengah (40 40 hex = note.

Perilaku default kelas MidiFile adalah untuk menyimpan waktu kutu absolut dari acara MIDI, tersedia di MidiEvent::tick , yang merupakan waktu kutu dari awal file ke acara saat ini. Dalam file MIDI standar, centang disimpan sebagai nilai delta, di mana centang menunjukkan durasi untuk menunggu karena pesan sebelumnya di trek. Untuk mengakses nilai kutu Delta, Anda dapat (1) subtrack waktu centang saat ini dari waktu centang sebelumnya dalam daftar, atau hubungi MidiFile::makeDeltaTime() untuk mengubah nilai centang absolut menjadi nilai centang delta.
Fungsi MidiFile::joinTracks() dapat digunakan untuk mengonversi data multi-track menjadi urutan waktu tunggal. Operasi joinTrack() dapat dibalik dengan memanggil fungsi MidiFile::splitTracks() . Berikut adalah sampel program yang bergabung dengan MidiEvents menjadi satu trek sehingga data dapat diproses dalam satu loop:
# 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 ;
}Di bawah ini adalah output jalur tunggal baru. Kolom pertama adalah stempel centang absolut dari pesan; Kolom kedua adalah nilai Delta Tick; Kolom ketiga adalah nilai trek asli; dan kolom terakhir berisi pesan MIDI (dalam byte hex).

Di bawah ini adalah contoh program untuk membuat file MIDI. Program ini akan menghasilkan urutan catatan acak dan menambahkannya ke akhir trek. Secara default objek MidiFile berisi satu trek dan akan ditulis sebagai file MIDI Tipe-0 kecuali jika lebih banyak trek ditambahkan. Setelah menambahkan catatan ke trek, itu harus diurutkan menjadi urutan waktu sebelum ditulis ke file.

Visualisasi dengan bin/mid2svg -s 6 -a 12 -v :
Berikut adalah contoh program minimal yang mengubah kode byte hex di atas menjadi file midi standar:
# 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;
} Fungsi MidiFile::read() akan secara otomatis mengidentifikasi apakah input adalah file midi standar biner, representasi kode byte hex, atau file sintaks Binasc yang digeneralisasi (yang termasuk kode byte). Fungsi MidiFile::status() dapat diperiksa setelah membaca file midi untuk menentukan apakah file dibaca tanpa masalah.
Contoh ini menggunakan MidiFile::getFileDurationInSeconds() untuk menghitung durasi file midi. Juga, contoh ini menunjukkan cara memproses beberapa file input saat menggunakan kelas opsi.
# 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 ;
} Fungsi MidiMessage::isText() akan mengembalikan true jika pesannya adalah pesan meta teks. Program berikut menggabungkan semua trek ke dalam satu daftar dan melakukan satu loop memeriksa meta-pesan teks, mencetaknya saat ditemukan. Fungsi MidiMessage::getMetaContent() mengekstrak string teks pesan dari byte file midi mentah.
# 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 ;
} Lirik yang mengekstraksi akan bekerja sama dengan menggunakan .isLyricText() bukan .isText() , dan meta-message track-name diidentifikasi oleh .isTrackName() .
Berikut adalah demonstrasi untuk mengubah file MIDI multi-track menjadi file midi satu-track:
# 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 ;
}
Fungsi .joinTracks() menggabungkan semua trek menjadi satu trek. Dan jika objek MidiFile hanya memiliki satu trek ketika sedang ditulis, itu akan ditulis sebagai file MIDI Tipe-0 (tunggal).
Secara umum file MIDI, trek drum ada di saluran ke -10, yang diwakili oleh Integer 9. Contoh berikut mencari melalui acara MIDI di setiap trek hingga menemukan catatan pada saluran 9:
# 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 ;
}Untuk beberapa aplikasi analisis musik, penting untuk menghapus catatan perkusi dari file MIDI. Berikut adalah contoh bagaimana hal itu dapat dilakukan dengan perpustakaan midifile.
# 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 ;
} Untuk menghapus pesan MIDI, hapus kelas dasar vektornya. Ini akan meninggalkan MidiEvent yang kosong di trek, tetapi fungsi MidiFile::write() akan mengabaikan setiap MidiMessage yang kosong. Fungsi MidiFile::removeEmpties() dapat dipanggil untuk secara eksplisit menghapus setiap MidiEvents kosong dari trek.
Contoh ini menunjukkan cara mengubah catatan dalam file MIDI. Perawatan harus diambil untuk menghindari transposing saluran 10 di MIDI umum, karena ini disediakan untuk trek drum (dan sebagian besar file MIDI menggunakan Konvensi MIDI Umum).
# 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 ;
}Contoh berikut mencantumkan semua nomor instrumen yang digunakan dalam file MIDI. Itu tidak menganalisis trek drum.
# 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 ;
}Jika Anda ingin mensimulasikan temperamen dalam file MIDI standar tanpa synthesizer yang secara khusus mengetahui tentang temperamen, maka contoh ini berguna. Setiap kelas pitch ditempatkan ke saluran trek dan midi yang terpisah. Pesan pitch-bend kemudian ditambahkan ke awal setiap trek di setiap saluran untuk mengontrol temperamen. Perawatan diambil untuk menghindari MIDI Channel 10, yang disediakan untuk timbres perkusi di MIDI umum.
# 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 ;
} Fungsi MidiFile::splitTracks() akan menghasilkan 13 atau 14 trek. Track 0 akan berisi semua pesan MIDI non-note dari file asli, sedangkan Tracks 1 hingga 12 akan berisi catatan kelas pitch tertentu di saluran MIDI 1-12, melewatkan saluran 10 (saluran perkusi MIDI umum). Catatan perkusi akan ditempatkan di trek 13, tetapi tetap di saluran 10.
Penggunaan MidiEvent::seq diatur ke 1 dan 2 dalam program ini digunakan untuk memaksa catatan pertama pada waktu kutu 0 ditempatkan setelah pesan tikungan pitch yang dimasukkan pada cap waktu yang sama ketika MidiFile::sortTracks() dipanggil (peristiwa dengan nomor urutan yang lebih rendah akan ditempatkan di depan mereka dengan angka yang lebih tinggi jika terjadi pada waktu yang sama di trek saat menguraikan acara di trek). Pesan pitch-bend mungkin akan diurutkan sebelum catatan, tetapi menggunakan seq harus menjamin mereka ditempatkan sebelum catatan pertama.

Contoh ini menunjukkan generasi vibrato konstan untuk catatan dalam file midi (pada saluran tertentu). Program ini menambahkan trek tambahan di akhir file untuk menyimpan tikungan pitch. Laju vibrato konstan terlepas dari pengaturan tempo untuk file MIDI, karena vibrato dihitung dalam waktu fisik daripada waktu centang. Fungsi MidiFile::getAbsoluteTickTime() menghitung konversi antara waktu fisik dalam detik dan waktu centang dalam file MIDI.

}Berikut adalah program yang menghasilkan pola polyrhythm. Opsi baris perintah adalah:
| pilihan | nilai default | arti |
|---|---|---|
-a | 2 | Divisi Siklus Instrumen Pertama |
-b | 3 | Divisi Siklus Instrumen Pertama |
-c | 10 | Jumlah siklus |
-d | 2.0 | durasi setiap siklus |
--key1 | 76 | Nomor kunci perkusi untuk instrumen pertama |
--key2 | 77 | Nomor kunci perkusi untuk instrumen pertama |
-o | nama file output |

} Program ini menunjukkan cara mengatur nilai kutu-per-kuartal di header MIDI. Dalam hal ini diatur ke faktor a*b yang merupakan durasi satu siklus (sehingga setiap siklus memiliki durasi seperempat not). Tempo meta-message juga dihitung berdasarkan durasi siklus yang diinginkan.
Misalnya, coba opsi -a 3 -b 4 -c 200 -d 1 -o 3x4.mid , yang akan memainkan pola 3 -against -4 untuk 200 siklus dengan setiap siklus berlangsung 1 detik. Atau di sini adalah 11 -AGAINST -13 untuk 100 siklus: -a 11 -b 13 -c 100 -d 5 -o 11x13.mid .
