The document describes an idea to generate personalized ringtones based on product barcodes scanned during shopping. It outlines the architecture to transform barcodes into musical notes using a ruleset and instrument set. The notes are saved as MIDI files and users can download the ringtone files from a website. It also describes using JFugue, an open source Java library, to specify and play musical patterns and save them as MIDI files without complex objects. Sample code shows how to generate and save the melody "Frere Jacques".

5. Idea
• Read in barcodes of bought products
• Generate individual song
• Customer downloads ringtone via website
• Music can be transformed back to data

7. Architecture

8. Basics
• Barcode to K-code transformation
• Use proper ruleset/instrumentset
• Save MIDI and record sampler output

10. SoS Net
• 2nd version using webinterface
Remote server application
✦
✦ Database for communication
• Usersniffing instead barcodes
• Reused same core logic

11. Sound Samples

12. JFugue

13. Features
• No complex objects, just (Music-)Strings
• Specify notes, chords, instruments & tracks
• Play at runtime, save to MIDI file
• Music can be sent to/received from devices

14. Example #1
import org.jfugue.Player;
public class Jsug {
public static void main(String[] args) {
Player player = new Player();
String musicString = quot;C D E F G A Bquot;;
player.play(musicString);
}
}

15. Example #2
// quot;Frere Jacquesquot;
Pattern pattern1 = new Pattern(quot;C5q D5q E5q C5qquot;);
// quot;Dormez-vous?quot;
Pattern pattern2 = new Pattern(quot;E5q F5q G5hquot;);
// quot;Sonnez les matinesquot;
Pattern pattern3 = new Pattern(quot;G5i A5i G5i F5i E5q C5qquot;);
// quot;Ding ding dongquot;
Pattern pattern4 = new Pattern(quot;C5q G4q C5hquot;);
Pattern song = new Pattern();
song.add(pattern1, 2); // Adds 'pattern1' to 'song' twice
song.add(pattern2, 2); // Adds 'pattern2' to 'song' twice
song.add(pattern3, 2); // Adds 'pattern3' to 'song' twice
song.add(pattern4, 2); // Adds 'pattern4' to 'song' twice
new Player().saveMidi(song, new File(quot;Frere Jacques.midquot;));
