Midifile is a library of C++ classes for reading/writing Standard MIDI files. The library consists of 6 classes:
| MidiFile | The main interface for dealing with MIDI files. The MidiFile class appears as a two dimensional array of MidiEvents: the first dimension is a list of tracks, and the second dimension is a list of MidiEvents. |
| MidiEventList | A data structure that manages the list of MidiEvents for a MIDI file track. |
| MidiEvent | The primary storage unit for MidiMessages in a MidiFile. The class consists of a tick timestamp (delta or absolute) and a vector of MIDI message bytes (or Standard MIDI File meta messages). |
| MidiMessage | The base class for MidiEvents. This is a STL vector of unsigned bytes representing a MIDI (or meta) message. |
| Binasc | A helper class for MidiFile that allows reading/writing of MIDI files in an ASCII format describing the bytes of the binary Standard MIDI Files. |
| Options | A optional convenience class used for parsing command-line options in the example programs. This class can be removed from the library since it is not needed for using the MidiFile class. |
Here is a schematic of how the classes are used together:
The MidiFile class contains a vector of tracks stored in MidiEventList
objects. The MidiEventList is itself a vector of MidiEvents, which stores
each MIDI event in the track. MidiEvents contain a timestamp and a MidiMessage
which is a vector of unsigned char values, storing the raw bytes of a MIDI message
(or meta-message).
Documentation is under construction at http://midifile.sapp.org. Essential examples for reading and writing MIDI files are given below.
You can download as a ZIP file from the Github page for the midifile library, or if you use git, then download with this command:
git clone https://github.com/craigsapp/midifileThis will create the midifile directory with the source code for the library.
The library can be compiled with the command:
make libraryThis will create the file lib/libmidifile.a which can be used to link
to programs that use the library. Example programs can be compiled with
the command:
make programsThis will compile all example programs in the tools directory. Compiled
example programs will be stored in the bin directory. To compile both the
library and the example programs all in one step, type:
makeTo compile only a single program, such as createmidifile, type:
make createmidifileYou can also place your own programs in tools, such as myprogram.cpp
and to compile type:
make myprogramThe compiled program will be bin/myprogram.
The easiest way to use the midifile library in your own project is to
copy the header files in the include directory and the source-code
files in the src directory into your own project. You do not
need to copy Options.h or Options.cpp since the MidiFile class is
not dependent on them. The verovio
and midiroll projects on Github
both use this method to use the midifile library. Alternatively, you
can fork the midifile repository and build a compiled lib
F438
rary file of
the source code that can be copied with the include directory contents
into your project.
The following program lists all MidiEvents in a MIDI file. The program iterates over each track, printing a list of all MIDI events in the track. For each event, the absolute tick timestamp for the performance time of the MIDI message is given, followed by the message itself as a list of hex bytes.
You can run the MidiFile::doTimeAnalysis() function to convert
the absolute tick timestamps into seconds, according to any tempo
meta-messages in the file (using a default tempo of 120 quarter notes
per minute if there are no tempo meta-messages). The absolute starting
time of the event is shown in the second column of the program's output.
The MidiFile::linkNotePairs() function can be used to match note-ons
and note-offs. When this is done, you can access the duration of the
note with MidiEvent::getDurationInSeconds() for note-on messages. The
note durations are shown in the third column of the program's output.
Note that the midifile library classes are in the smf namespace,
so using namespace smf; or smf:: prefixes are needed to access
the classes.
#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 << "\nTrack " << track << endl;
cout << "Tick\tSeconds\tDur\tMessage" << 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;
}The above example program will read the first filename it finds on
the command-line, or it will read from standard input if no arguments
are found. Both binary standard MIDI files and ASCII representations
of MIDI Files can be input into the program. For example, save the
following text into a file called twinkle.txt to use as input data.
This content represents the hex bytes for a standard MIDI file, which
will automatically be parsed by the MidiFile class.

Below is the output from the example program given the above input data. The
TPQ value is the ticks-per-quarter-note value from the MIDI header. In
this example, each quarter note has a duration of 120 MIDI file ticks. The
above MIDI file contains three tracks, with the first track (the expression
track, having no content other than the end-of-track meta message, ff 2f 00
in hex bytes. The second track starts with a MIDI note-on message 90 48 40
(in hex) which will start playing MIDI note 72 (C pitch one octave above
middle C) with a medium loudness (40 hex = 64 in decimal notation).

The default behavior of the MidiFile class is to store the absolute
tick times of MIDI events, available in MidiEvent::tick, which is the
tick time from the start of the file to the current event. In standard
MIDI files, tick are stored as delta values, where the tick indicates the
duration to wait since the previous message in a track. To access the
delta tick values, you can either (1) subtrack the current tick time from
the previous tick time in the list, or call MidiFile::makeDeltaTime()
to convert the absolute tick values into delta tick values.
The MidiFile::joinTracks() function can be used to convert multi-track
data into a single time sequence. The joinTrack() operation can be
reversed by calling the MidiFile::splitTracks() function. Here is a sample
of program that joins the MidiEvents into a single track so that the
data can be processed in a single 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;
}Below is the new single-track output. The first column is the absolute tick timestamp of the message; the second column is the delta tick value; the third column is the original track value; and the last column contains the MIDI message (in hex bytes).

Below is an example program to create a MIDI file. This program will
generate a random sequence of notes and append them to the end of
the track. By default a MidiFile object contains a single track and
will be written as a type-0 MIDI file unless more tracks are added. After
adding notes to the track, it must be sorted into time sequence
before being written to a file.

Visualization with bin/mid2svg -s 6 -a 12 -v:
Here is an example minimal program that converts the above hex byte-codes into a standard MIDI file:
#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;
}The MidiFile::read() function will automatically identify if the
input is a binary standard MIDI file, a hex byte-code representation,
or a generalized binasc syntax file (which includes byte-codes).
The MidiFile::status() function can be checked after reading a MIDI
file to determine if the file was read without problems.
This example uses the MidiFile::getFileDurationInSeconds() to calculate the
duration of a MIDI file. Also, this example shows how to process multiple
input files when using the Options class.
#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;
}The MidiMessage::isText() function will return true if the message
is a text meta-message. The following program merges all tracks into
a single list and does one loop checking for text meta-messages, printing
them out when found. The MidiMessage::getMetaContent() function extracts
the text string of the message from the raw MIDI file bytes.
#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;
}Extracting lyrics would work the same by using .isLyricText() instead of
.isText(), and a track-name meta-message is identified by .isTrackName().
Here is a demonstration of converting a multi-track MIDI file into a single-track MIDI file:
#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;
}
The .joinTracks() function merges all tracks into a single track. And if
a MidiFile object has only one track when it is being written, it will be
written as a type-0 (single-track) MIDI file.
In General MIDI files, the drum track is on the 10th channel, which is represented by the integer 9. The following example searches through the MIDI events in each track until it finds a note on channel 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;
}For some music-analysis applications, it is useful to remove percussion notes from a MIDI file. Here is an example of how that can be done with the midifile library.
#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())
10000
{
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;
}To delete a MIDI message, clear its vector base class. This will
leave an empty MidiEvent in the track, but the MidiFile::write()
function will ignore any empty MidiMessages. The
MidiFile::removeEmpties() function can be called to explicitly remove
any empty MidiEvents from the track.
This example shows how to transpose notes in a MIDI file. Care should be taken to avoid transposing channel 10 in General MIDI, since this is reserved for the drum track (and most MIDI files use the General MIDI convention).
#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;
}The following example lists all of the instrument numbers used in a MIDI file. It does not analyze the drum track.
#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 << "\tInstrument:" << it.second << endl;
return 0;
}If you want to simulate temperaments in a Standard MIDI file without a synthesizer that specifically knows about temperaments, then this example is useful. Each pitch-class is placed into a separate track and MIDI channel. A pitch-bend message is then added to the start of each track in each channel to control the temperament. Care is taken to avoid MIDI channel 10, which is reserved for percussion timbres in General MIDI.
#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;
}The MidiFile::splitTracks() function will generate 13 or 14 tracks. Track 0
will contain all non-note MIDI messages from the original file, while tracks
1 to 12 will contain notes of a specific pitch-class on MIDI channels 1-12,
skipping channel 10 (the General MIDI percussion channel). Percussion notes
will be placed in track 13, but remain on channel 10.
The use of MidiEvent::seq being set to 1 and 2 in the program is used to
force the first notes at tick time 0 to be placed after the pitch bend
messages inserted at the same timestamp when MidiFile::sortTracks()
is called (events with a lower sequence number will be placed before those
with a higher number if they occur at the same time in a track when sorting
the events in the track). The pitch-bend messages would probably be sorted
before the notes anyway, but using seq should guarantee they are placed
before the first notes.

The following program takes a multi-track MIDI file with three or more tracks, and splits out each track into a separate MIDI file. The expression track of the original MIDI file is copied into the 0th track of the new MIDI files, and the individual tracks of the first MIDI file are copied to the 1st track of the output MIDI files.

return 1;
}

This example demonstrates the generation of a constant vibrato for notes
in a MIDI file (on a particular channel). The program adds an extra
track at the end of the file to store the pitch bends. The vibrato
rate is constant regardless of the tempo setting for the MIDI file,
since the vibrato is calculated in physical time rather than tick time.
The MidiFile::getAbsoluteTickTime() function calculates the conversion
between physical time in seconds and tick time in the MIDI file.

}Here is a program that generates polyrhythm patterns. Command line options are:
| option | default value | meaning |
|---|---|---|
-a |
2 | first instrument's division of the cycle |
-b |
3 | first instrument's division of the cycle |
-c |
10 | number of cycles |
-d |
2.0 | duration of each cycle |
--key1 |
76 | percussion key number for first instrument |
--key2 |
77 | percussion key number for first instrument |
-o |

}This program demonstrates how to set the ticks-per-quarter-note value in the
MIDI header. In this case it is set to the factor of a*b which is the duration
of one cycle (so each cycle has the duration of a quarter note). A tempo meta-message
is also calculated based on the desired duration of a cycle.
For example, try the options -a 3 -b 4 -c 200 -d 1 -o 3x4.mid, which will play
a 3-against-4 pattern for 200 cycles with each cycle lasting 1 second. Or here
is 11-against-13 for 100 cycles: -a 11 -b 13 -c 100 -d 5 -o 11x13.mid.
