Subject: Call for Shoes From: "Henkjan Honing, UvA (++31- 20 - 525 4698/2181)" <honing(at)MARS.LET.UVA.NL> Date: Tue, 28 Sep 1993 13:43:49 +0100Dear Colleague, We think it would be a good idea to bring together the contributions of different researchers to the field of automatic foottapping, beat or metre extraction, and tempo following for interactive computer music systems. This could take the form of a demonstration and/or paper session at ICMC 1994. We would like to add a fun side by supplying a platform of MIDI controlable mechanical shoes for a demonstration of the systems and an educational side by somehow presenting an overview of the methods used. Do you think this is a good idea? Do you want to participate? Could you make your algorithm available? Any more fun ideas? Please e-mail you reaction to desain(at)nici.kun.nl Best regards, Peter and Henkjan The next text has been submitted to Array: ======================================================================== CALL FOR SHOES Beat-tracking (also referred to as tempo-tracking or foot-tapping) is a difficult problem, crucial to enable good interactive composition systems. This proccess extracts from incomming (MIDI) events a periodical pulse at an appropriate metrical level (tactus). The beat is an essential reference for many subsequent structural analyses (at least for some kinds of music). Many ideas and systems exist, all more or less successfull. For the ICMC 1994 we would like to submit some sort of demonstration or installation in which different foot-tapping algorithms will listen to the same music, each with its own mechanical MIDI-controlled tapping shoe. Researchers are invited to submit an algorithm and a shoe. And all ideas about how we can make this into an enlightening experience are welcome. We would be very happy if, with your help, we could learn from individual approaches and uncover an inventarisation of the methods used. Apart from the installation itself, we think of proposing a foot- tapping paper session. Students who could help getting this realized as part of their study - please repond too. Please send Email before shoe.
