Check out the official announcement at: http://orpheus.ucsd.edu/dept.music/musicdept/facjobs.html ... and look for the third item, "computer music". This isn't the same as the "computer artists/educator" job -- it's real computer music, research and teaching. cheers Miller

by Tom Erbe 28 Oct '02

28 Oct '02

CEAIT Festival 2003 - January 10-12 (Friday - Sunday) - Call for Submissions The Center for Experiments in Art, Information, and Technology (CEAIT) is holding its 6th annual festival of electronic music. The festival is student-organized and, over the past five years, has presented a wide range of performances and installations, many of which integrated media outside audio such as dance, video, text and computer graphics. Presentations have included works by Maggi Payne, Todd Winkler, Pamela Z, Joe Colley, Blectum from Blechdom, Bob Gonsalves, Ted Apel, Douglas Repetto, and many others. We are accepting proposals for presentation at this year's festival, January 10-12, 2003. SUBMISSION GUIDELINES We accept pieces that are max. 15 minutes long. Pieces for: live electronics, instrumental performers with tape or computer, tape alone, video tape, or computer alone; audio and web installations will also be considered provided that the artist or group be responsible for set up and maintenance of their piece. There is a preference for live work over tape/CD only pieces, although tape/CD only pieces will also be programmed. A composer or group may submit up to two works. We accept submissions on Compact Disc, VHS, CD-ROM, or DVD. For pieces involving performers, the composer needs to provide the performers and make necessary arrangements for the performance. For pieces with image, we will have a projector with VHS, DVD, or CD-ROM playback available. All video Submissions should be in NTSC format. Please provide a representative version of what will be performed live. Please include with each submission: - bios - program notes - composer's or group's contact information including email - a list of technical requirements Please note: The festival does not provide financial support for any travel or production expenses. Any submitted materials cannot be returned unless an SASE is included in the submission.

os x.2 (jaguar) & motu usb fastlane midi interface...
by Patrick Rost 28 Oct '02

28 Oct '02

hi all, i've been trying to get cracking at miagrating all my old midi max patches into pd, but a working interface is necessary! i'm running a TiBook/500, usb motu fastlane w/ the beta drivers from versiontracker (v 1.0b4)...& pd complains [pb01:~] psnd74_% pd -> could not open midi input device number 1: Invalid device ID. -> could not open midi output device number 1: Invalid device ID. using default input device number: 0 using default output device number: 1 nchan 2, flags 3, bufs 8, framesperbuf 256 PortAudio on OS X - Latency = 2048 frames, 46 msec & upon exiting, FWADisposeMIDIStream result = 1 the interface shows up in the Audio MIDI Setup app (Applications/Utilities) i don't have any other midi software to test this interface with (and pd is the reason i bought it anyway...) any ideas, or am i doomed to just waiting some more & firing up the mac classic, because IT does midi just fine? thanks, Patrick T. Rost psound(a)queerio.com

Re: Re: [PD] fftw
by Michael Iber 26 Oct '02

26 Oct '02

Hello Thomas, Scott and list, I would like to build an external, which is a combination of the Native Instruments Spectral Delay and a trigger mechanism in the analysis stage (depending on amplitude) for single bins. I tried to build it with the objects available for PD, but although limiting it to only 200 bins, it couldn't be anything serious to use. Since as far as I know the Spectral Delay is build on the FFTW-algorithm (using the full spectrum), which seems to be the fastest freely available, I would like to use it for my external to. Thanks for your help Michael Michael Iber http://www.iberspace.de mailto://mail@iber-online.de

question about convolution
by J. Scott Hildebrand 26 Oct '02

26 Oct '02

right now everything is working as it should, except for some unwelcome "clicks" when changing the location of the sound (changing the HRTFs). i tried writing a linear interpolation algorithm but that didn't fix the problem. the location of the sound is specified by integers that are the 3rd and 4th inlets into the external. i'm wondering if the problem is that everytime i switch the HRTFs, then the whole code starts over and the previous block of samples is cut short; this would explain a click only when the filters are changed. at the end of this email is my code for the inlet/outlet declaration. are these inlets all active? and would making them inactive possibly fix the problem? i'm really stuck so if anybody can help out i'd really appreciate it! scott static void *convaudio2_tilde_new(t_floatarg f) { t_convaudio2_tilde *x = (t_convaudio2_tilde *)pd_new(convaudio2_tilde_class); x->f_convaudio2 = f; inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("first")); inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("bound")); outlet_new(&x->x_obj, &s_signal); outlet_new(&x->x_obj, &s_signal); /* second outlet for stereo */ return (void *)x; } -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

Comport working, still some problems
by Martin Dupras 26 Oct '02

26 Oct '02

Hi, Thanks to all who contributed answers. That was very useful and prompt! I have tried Comport, and I'm happy to say that it does seem to work. I have to do some more extensive, but it looks very promising. Thanks again! -martin
