+# node-midi
+
+A node.js wrapper for the RtMidi C++ library that provides realtime MIDI I/O.
+RtMidi supports Linux (ALSA & Jack), Macintosh OS X (CoreMidi), Windows
+(Multimedia), although node-midi has only been tested briefly on Mac OS X.
+
+## Installation
+
+	$ node-waf configure && node-waf build
+
+## Usage
+
+Input:
+
+    var midi = require('midi');
+
+    // Set up a new input.
+    var input = new midi.input();
+
+    // Count the available input ports.
+    input.getPortCount();
+
+    // Get the name of a specified input port.
+    input.getPortName(0);
+
+    // Configure a callback.
+    input.on('message', function(deltaTime, message) {
+	  console.log('m:' + message + ' d:' + deltaTime);
+    }); 
+        
+    // Open the first available input port.
+    input.openPort(0);
+
+    // ... receive MIDI messages ...
+
+    // Close the port when done.
+    input.closePort();
+
+Output:
+
+    var midi = require('midi');
+
+    // Set up a new output.
+    var output = new midi.output();
+
+    // Count the available output ports.
+    output.getPortCount();
+
+    // Get the name of a specified output port.
+    output.getPortName(0); 
+        
+    // Open the first available output port.
+    output.openPort(0);
+
+    // Send a MIDI message.
+    output.sendMessage([176,22,1]);
+
+    // Close the port when done.
+    output.closePort();
