This is my first use of midi in Processing. I do not use the MidiBus<\/a> library for Processing. Instead, I try to use the standard midi package<\/a> in Java. The SE8 standard Java package also contains the javadoc<\/a> documentation.<\/p>\n\n\n\n

The Processing source code and sample midi files are in the Magicandlove GitHub repository<\/a>. The midi example files are downloaded from the midiworld<\/a> website.<\/p>\n\n\n\n

The code basically needs a Synthesizer<\/a> class to render midi instruments into audio and a Sequencer<\/a> class to playback the midi sequence.<\/p>\n\n\n\n

Synthesizer synth = MidiSystem.getSynthesizer();
Sequencer player = MidiSystem.getSequencer();
synth.open();
player.open();<\/pre>\n\n\n\n
All the midi music files are in the data<\/em> folder of the Processing sketch. To playback each piece of midi music, we need to convert each into a Java File<\/a> object and use the following code to playback it. The variable f<\/em> is a File<\/em> object instance containing the midi file in the data<\/em> folder.<\/p>\n\n\n\n
Sequence music = MidiSystem.getSequence(f);
player.setSequence(music);
player.start();<\/pre>\n","protected":false},"excerpt":{"rendered":"
