Java MIDI - getting data from piano?

Question

I've inherited a Java project that used an old C++ dll to receive MIDI data from a piano connected to the computer.

Now that Java has built-in support for MIDI devices, I want to get rid of the legacy C++ dll and just use pure Java. Does Java support receiving data from a piano connected to the computer? I've searched Google for examples to no avail.

Answer 1

Here is an example of pure java that Listens to a MIDI port and dump the received event to the console. You should be able to run with that. :)

Answer 2

Yes, the JavaSound API can be used to read MIDI data from a MIDI device.

JFugue is a Java API for music programming that uses the JavaSound API, and can help simplify your interaction with JavaSound. In JFugue, sample code to capture 10 seconds of MIDI data from a MIDI device is as follows:

DeviceThatWillTransmitMidi device = new DeviceThatWillTransmitMidi(); 
device.listenForMillis(10000); 
Sequence music = device.getSequenceFromListening();
