Work In Progress...
Java bindings to RtMidi using JNR-FFI written in Koltin.
TODO
A ReadableMidiPort
is one that you as a programmer can read messages from, similarly a
WritableMidiPort
is one that you as a programmer can send messages to.
You can query all readable and writable MIDI ports in the system by using the
RtMidi class's static functions:
List<MidiPort.Info> readablePorts = RtMidi.readableMidiPorts();
List<MidiPort.Info> writablePorts = RtMidi.writableMidiPorts();These return MidiPort.Infos which are then used to create a port such as:
ReadableMidiPort readablePort = new ReadableMidiPort(readablePorts.get(0));
WritableMidiPort writablePort = new WritableMidiPort(writablePorts.get(0));You can then open() a port to be ready to send or receive messages:
readablePort.open(/*portName=*/"My Readable Port");
readablePort.setCallback((MidiMessage midiMessage,double deltaTime) -> {
// Your callback code here, note this code is real time critical!
});Once you are done with a port, be sure to call destroy(), after which you will only be able to query the port
readablePort.destroy(); // closes and destroys
readablePort.getInfo(); // ok
readablePort.isDestroyed(); // ok
readablePort.open(/*portName=*/"My Readable Port"); // ERROR: will throw RtMidiPortException!
readablePort.destroy(); // ok, will not do anything if already destroyedJRtMidi's documentation is extensive and thorough and it is recommended to read through it to understand the capabilities of the library.
