  1. PTL, a graphical sequencer dedicated to pure-data Graz, I.E.M. 2004

  2. Paris Damien HENRY Acoustical Engineer Code since ZX81 Play electronic music since AWE32 Use pd since version 27 Create the « pd internal msg » documentation Create Xgui a set of objects to allows a pd user to create any kind of graphical interface. Give pd courses for artists & engineer Play in chdh band (tonight @ MKL) Damien.henry@dh7.net

  3. Plan : Graphical scores and electronic music ? Midi (and electronic music) Alternatives Ptl : goals Ptl short demo Problems Conclusion

  4. Graphical scores Iannis XENAKIS, Mycenae alpha

  5. Graphical scores Cornelius Cardew, Treatise

  6. Graphical scores Cornelius Cardew, Treatise

  7. Stockhausen, Super formula for Licht.

  8. Graphical scores Graphical scores seems to fit particularly well the aim of representing Electronic music. Graphical score are OPEN : no more fixed symbol like in the classical notation system The author of a graphical score is free to use any graphical pattern and associate them with any kind of sound.

  9. Midi is dead ? Midi is too limited regarding what pd offer. Pd is hard to drive using a classical sequencer New solution like OSC are coming and seems to be good and used.

  10. Alternatives Open music, Ircam

  11. Alternatives Pure data data-structures

  12. Alternatives PTL

  13. Why PTL ? Today no sequencer dedicated to graphical scores. Today there is no OSC sequencer. No sequencer is able record live performance when using hi-resolution devices (like kroonde from la-kitchen.fr) ; edit it ; replay.

  14. Why PTL ? Using pure-data as a sequencer for recording, drawing and playing a graphical score seems to be possible using data-structures ; but it’s a skilled work to create such a complex pd patch. Moreover, basic features like zooming or splitting events are not implemented yet. Creating a stand alone solution is more flexible : you can use it to drive pd or to export a qlist, create a patch, drive any other OSC instrument.

  15. PTL Goal Offer to composer an easy to use interface for creating and playing graphical score No pre-defined link between graphic and sound, this must be up to the composer.

  16. PTL – combine event

  17. PTL short demo

  18. PTL today PTL is implemented in java Use XML files Use the FUDI protocol for driving pd. Use inheritance for easy extension for any new ptl-object. Is able to render a Qlist. Open Source Licence

  19. Problems PTL is poorly design : no undo redo chain ; not based onto a robust Document-view model. The user graphic interface is too slow No documentation  OSC not implemented yet The only developer is overbooked !

  20. Future Redesign for undo redo, quicker user interface. OSC Export as pd-patch ? Render as patch ? Render as cScore ? Implement sound and open GL ;-)

  21. Help ! I won’t succeed this project alone Need for other contributor : documentation, coding, testing. Main hot topics : speed up the user interface ; find a better design. => Damien.henry@dh7.net

  22. Conclusion There is a place for a stand alone software dedicated to graphical score for electronic music. PTL offer the composer a tools to create, edit, record and play, graphical score that looks the way he want. Contributions are needed to achieve the project.
