This report was written with WinWord 6 and contains embedded diagrams. Sounds interesting. I could put it on my web page, which would make it available worldwide, and people could read it online to boot, if I convert it to html (not that hard). -- ------------------------------ Date: Wed, 2 Nov 1994 17:00:06 EST From: Jason Price Subject: Re: CAN >>First there was a demand for my report of my studies on >>the CAN network.

To Borris and Shawn: Please keep the other subscribers and myself posted on the development of the Idea of putting Borris' report on the internet. I am very interested in getting my hands on it.

I've made some calculations for the real time abilities of the M-CAN in the music domain and it came out that to send a worst-case event (a 3 byte message like a note-on or note-off), it will be slightly more that 10 time faster than midi, sounds good. For longer messages (up to 8 bytes, like syst. messages), it should be almost 20 time faster. As i'm far to know everything about midi, i would like to know if some people here would like to help me, maybe there's a midi specific discussion somewhere, i don't know. I need some informations about the midi hardware, (the exact timing of the messages), its restrictions and advantages, do you have ideas ? If so, please help me, i will not be able to do anything good without any help. Regards, Boris. ---------------------------------------------------------------------- We're livin' the Orwellian age...

They are concerned with the fact that the MIDI bandwidth is not large enough to allow for the amount of information their modern controllers can support (such as guitar or violin controllers). The use of several different continuous controllers simultaneously can easily eat up the bitstream, and that is only one instrument. Also, MIDI makes no provisions for a note-update event: pitch and velocity are set at note-on time, and unchangeable. This is fine for keyboard type instruments, but what about those instruments which have a varying pitch (slide trombone, glissando on a violin, etc.)? Matthew Wright (Center for New Music and Audio Technologies (CNMAT) Department of Music, University of California, Berkeley) is publishing an article in thw winter Computer Music Journal about ZIPI. Actual ZIPI devices are slated for early '95 release. I also have his faq about ZIPI, if someone wants to tell me the address of the ftp site I will put it there.

I can't see ZIPI getting anywhere until there are software packages (and computers fast enough to cope and to present the information), and ZIPI computer interfaces (and computers fast enough etc.). Until then, ZIPI offers not much over the usual audio (except the ability to control one instrument from another; are there any rackmount ZIPI modules yet?).

Until then, ZIPI >offers not much over the usual audio (except the ability to control one >instrument from another; are there any rackmount ZIPI modules yet?). True Nick......until then, however. I doubt there are ZIPI anything(s) except on paper. I still find it interesting and am willing to pay $10 for the CMJ issue. I think something you may benefit from in your work are the realtime control changes that the protocol seems to offer. i.e. altering the course of events midstream. I like that. I guess the one thing that bothers me the most (that can't seem to be overcome by creative MIDI filtering/processing/routing) is the damn velocity range of 0-127 fixed into MIDI. Squaring it to 16384 might be excessive, but I'll take it. _ -john ___ __/ | ___ | | JKrikawa@CCIT.Arizona.Edu | |___ ________ \______/ \__________ Tucson, AZ ___../\./\/ \____/ \____ ------------------------------ Date: Sun, 27 Nov 1994 08:34:25 +1000 From: David Rodger Subject: Re: ZIPI: CMJ article should be interesting. Hi Nick and all who have contributed to this thread, The originator of this posted it under the subject title > ZIPI: CMJ article should be interesting. Is there a CMJ article? I haven't seen it, but then my uni library takes a while to get CMJ. Any other references would be useful, too. Regards and thanks, David ------------------------------ Date: Wed, 30 Nov 1994 16:27:14 -0500 From: "Leo T. Nutley" Subject: midi protocol I've been trying to find the format for sending basic midi messages (note on/off etc.) and haven't had any luck. The librairy here in San Francisco has lost every book on the subject and i'm stuck. Either a faq or a book reccomendation (future basic, pascal, or..) would be appreciated. With the service that i'm on, ftp sites are not as available as i'd like, so even though the info on such places is good for future reference, i have to go to more old-fashoned sources. bla bla bla. 577 subscribers * us$3.50/pint = $2,019.50. They'd love us at the old 'Pig and Whistle'. leo ------------------------------ End of the EMUSIC-L Digest ******************************
