Random MIDI tune with Scala and the Java MIDI API.

gistfile1.scala

package org.kafecho.learning.midi
import javax.sound.midi.MidiSystem
import javax.sound.midi.ShortMessage
import scala.util.Random

object MidiTest extends App {
  val rcvr = MidiSystem.getReceiver
  while (true) {
    val myMsg = new ShortMessage
    myMsg.setMessage(ShortMessage.NOTE_ON, 8, Random.nextInt.abs % 127, 93)
    rcvr.send(myMsg, -1)
    Thread.sleep(100)
  }
}

THANK YOU SO MUCH FOR POSTING THIS CODE! I'VE BEEN TRYING TO FIGURE OUT HOW TO GENERATE SOUND, IN A SIMPLE WAY, USING SCALA (USING OS X) FOR 3 WEEKS. WHEN YOU HAVE TIME, CAN YOU PLEASE CREATE AN EXAMPLE OF HOW TO CHANGE THE TYPE OF SOUND /INSTRUMENT THAT'S PLAYED?

THANK YOU

I did quite a lot of MIDI work but that was ages ago, however I can't remember from the top of my head. Have a look at: http://docs.oracle.com/javase/tutorial/sound/ for inspiration
