I'm new to matlab and am wondering if this is possible for a college project.
I want to make a synthesizer, it'll use java to take in MIDI messages from an external MIDI keyboard and will generate sounds in real-time.

Perhaps using udp messages, but i don't see why use Matlab because I don't know any way of working in the score level :/

Hi Craig,
There's a MIDI Interface available in File Exchange for MIDI input. It's Windows-only.
In order to generate real-time sound in MATLAB, you'll need an ability to buffer sound going to the audio interface. The DSP System Toolbox comes with such an ability (dsp.AudioPlayer) and also includes low-latency ASIO drivers (these are for Windows; Mac's native drivers are already low latency). Another File Exchange entry (the Real Time Audio Processor) provides a real-time sound generation framework and an example of building a simple synthesizer in MATLAB. It also includes the MIDI Interface from above.
