  1. THE DJ AESTHETIC:A LOOK INTO THE PHILOSOPHY AND TECHNOLOGY THAT ENABLE THE DISC JOCKEY ZACHARY HELLMAN

  2. DESIGNING DJ AUTOMATA • Principles for Designing Computer Music Controllers • By Perry Cook • Some Human/Artistic Principles • 1. Programmability is a curse • 2. Smart instruments are often not smart • 3. Copying an instrument is dumb, leveraging expert technique is smart • 4. Some players have spare bandwidth, some do not • 5. Make a piece, not an instrument or controller • 6. Instant music, subtlety later

  3. Some Technological Principles • 7. MIDI = Miracle, Industry Designed, (In)adequate • 8. Batteries, Die (a command, not an observation) • 9. Wires are not that bad (compared to wireless) • Some Other Principles • 10. New algorithms suggest new controllers • 11. New controllers suggest new algorithms • 12. Existing instruments suggest new controllers • 13. Everyday objects suggest amusing controllers • (Cook, NIME, 2001)

  4. TRADITIONAL/SERATO DJ SETUP

  5. FUNDAMENTAL REVIEW

  6. QUALITATIVE TEMPO TRAJECTORY (QTT)

  7. hpDJ: THE AUTOMATED DJ

  8. MONITORING CROWD AND USER RESPONSE

  9. THE VISUAL REPRESENTATION OF AUDIO CONTENT

  10. CROSS FADE MIXING AND THE AUTOMATED COMPILATION OF MUSIC

  11. EVOLUTIONARY COMPUTATION & GENETIC PROGRAMMING • A genetic algorithm (GA) operates on a bunch of candidate solutions to some problem, revered to as a population of individuals.(see e.g. Goldberg, 1989; Mitchell, 1996) • A string of values represent the genes of a track • A GA requires a testing system to assign an individual a score known as its fitness. Individuals with higher fitness scores are more likely to be chosen for breeding. • This sequence of test-breed-replace is referred to as one generation.

  13. RELATED DJ AUTOMATA • Basu, Sumit. 2006: System and Method for Aligning and Mixing Songs of Arbitrary Genres. US patent number 7,081,582; issued on 25 July 2006; assignee: Microsoft Corporation. • Fujio, Tsuyoshi, Hisao Shiizuka. A System of Mixing Songs for Automatic DJ Performance using Genetic Programming, Graduate school of Kogakuin University, Tokyo, Japan, 2003 • Shteyn, Eugene. Media Player with “DJ” Mode. US Patent 6,933,432, August 2005.

  14. PRINCIPLES FOR DESIGNING DJ AUTOMATA Automated systems require a great deal of user control Unlike new instruments, DJ automata should be deeply rooted in traditional DJ technology If it isn't broken, don't fix it. Unfamiliarity is unsettling for DJs Interactivity increases your audience data, not aesthetic possibilities Analog shortcomings should not be replicated in digital systems Algorithms can simulate, not replicate The DJ/system is the performer, not the audience Machine sensibility is deceptive Bad music can't be used to make good music (Good input = the likelihood of good output) The turntable offers limitless possibilities for musical performance

  15. Great DJ Do it to share great music with people. Be yourself. Concentrate on finding great music. Learn the history of the music you love and buy classic records. Find floor fillers that no one else will ever get hold of. Have fiercely individual taste and carve out a unique style that no one can easily describe. Don’t restrict yourself to a narrow style of music. Take risks with strange and unfamiliar records. Have fun; imagine yourself on the dance floor. Ruthless DJ Do it to be famous, rich, and more sexually attractive. Get an image. Concentrate on getting in magazines. Try to jump on the next big thing before anyone else. Find floor fillers that everyone else will play, but get to them first. Make sure your style can be pigeonholed so dumb promoters don’t have to think too hard. Figure out upcoming trends and play lots of records from that genre. Play only what you’re sure the crowd will approve of. Take it seriously; imagine yourself in Urb.
