Playing
back music with the internal JavaSound synthesizer limits the sounds
and sound quality of your music. It take advantage of the array of
external music synthesizers SoundCipher can send its output via the
computers Musical Instrument Digital Interface (MIDI) output.
A
note of warning to users of Apple's OS X operating system that external
JavaSound output is not supported on Apple's Java implementation but
you can install the Mandalone extension to use this feature. It
is available at www.mandalone.co.uk
The first line imports the SoundCipher library into the sketch. The
second line sets up a SoundCipher instance called sc for use in the
program.
The
setup() method calls a static method that gets the current MIDI devices
and prints them to the console window. This is for you information
really and you may need to use this to change the next line that sets
the desired MIDI output device. The number 1 may or may not be
appropriate for your system. Be aware that the devices that are
reported to the console include both input and output devices. Finally,
the frameRate is set to 1 frame per second. This is used to control how
often the draw() method is called; which in this program controls the
music playback.
The draw() method is used to play a note which
should be sent to the desired MIDI output. The pitch is a randomly
selected from a C pentatonic scale between note 60 and 72; the octave
starting at middle C. |
