Well, here's one inelegant possibility, using a selector~ to switch
mid-cycle between two phasor scale factors, then indexing a cycle with the
result. It's somewhat sawtooth-like at the extremes, but based on the CPU
utilization it might be cheaper to buy an old Casio.

Subject: USB to ADB

Howdy ya'll, I have a question somone has to know the answer to. I want to
hook up a gold brick to a friends fancy clear blue G3, which doesn't have
an ADB as we all sadly know. Now I saw in a magazine an device (A cable I
think?) called the "IMATE USB TO ADB adapter"Will max see this as ADB
and be able to poll my power glove through it? It is a bit of a gamble for
$80, I wanted your oppinions first. Also do any of you have any experince
with MAX through the event electronics DA/AD cards that also have MIDI?
Thankx, Little Dave.

Subject: crashes continued

Hi List,

thanks for the notes about crashes.

one thing I have determined that MAY be PART of the problem, though I am sure
not all:

On my Mac, even if I set the relevant control panel such that the hard disk
should NEVER spin down, in fact it still DOES. Once it has spun down, there
seem to be some things Max/MSP can do which will crash the machine.

This is on a Powerbook 4000mhz with OS8.6

I am trying keeping a "stupid" patcher which reads a one line coll file once
a minute to see if i can keep the drive from spinning down.

One of the first things I did was to disable sleep mode completely. It is
incompatible with dsp, which can't sleep. It crashed msp whenever it
tried to put the machine sleep.

Subject: Re: sys error 2crash problems

I also have a lot of problems with system error 2. its happening with a
patch ive made with my own signal external, that spits out cellular
automata type buffers. the patch that im using also contains an uzi
object, that uses peek to feed a buffer into a large multislider. the
crash occurs at times when im opening a subpatch, turning on or off dsp,


changing the vector size, or changing the input of a selector object.
sometimes this will crash immediately, at other times it will run for 30
minutes without a problem. what exactly does sys error 2 with msp mean,
so if there is a problem in my external code i can look out for it?

Ninth Annual Florida Electroacoustic Music Festival
April 6-8, 1999
University of Florida

Composer-in-Residence, Barry Truax

Now in its ninth year, the Florida Electroacoustic Music Festival has
featured an international variety of contemporary electroacoustic art
music. Past composers-in-residence have included internationally
renowned composers such as Hubert S. Howe, Jr., Cort Lippe, Gary
Nelson, Jon Appleton, Joel Chadabe, and Larry Austin.


Call for Works

A call for electroacoustic art music works at fit into the following
categories:

works for tape alone
- special interest in "soundscape" works (though not limited to)
- octophonic works (see formats available)

works for tape and instrumental solo
- special interest in works including flute,
saxophone, horn, trombone, string bass, piano, and percussion

works for tape and baritone voice


works utilizing interactive applications
- Opcode's Max/Cycling '74's Msp
- IRCAM MAX/FTS (SGI O2 platform)

media formats supported: CD, DAT, Tascam DA-88/38, 1/4"
1/2-track, and 1/4" 4-track

Deadline for the receipt of submitted work(s) is: October 30, 1999

All works that include live performance need to be accompanied by a
tape of a performance or high quality realization. All submissions
must include performance materials in the available media listed
above, performance parts and/or score, brief biography (75-100
words), program notes (concise), and contact information sheet.
Incomplete submissions will not be reviewed. Please note if the
composer can provide a performer. Contact information sheet must
include a phone number, address, and if available email address, www
site, and fax number. A self-addressed stamped envelope (SASE) is
required for the return of all materials (or international postal
response return coupons). Tapes of works for performance and those
not accompanied by an SASE will become the property of the Florida
Electroacoustic Music Studio.

All composers selected for performance are required to attend the
festival; this is to provide a sense of community to the festival.
There are no travel grants available directly from the festival.
Should a composer be unable to attend the festival their work will
not be presented.

**************

Call for Papers/Presentations

A call for papers, studio reports, and lecture/demonstrations dealing
with all aspects of electroacoustic music, computer music, digital
music, acoustics, psychoacoustics, and related topics. Submissions
from all current areas of electroacoustic music research and historic
perspectives are encouraged. Special interest is given to
submissions dealing with acoustic ecology, interactive
composition/synthesis, algorithmic composition, mew musical
interfaces, and new techniques in wavelet/quantum synthesis.

Deadline for the receipt of submitted materials is: October 30, 1999

Three copies of the completed paper, studio report, or
lecture/demonstration abstract music be accompanied by a brief
biography of 75-100 words (abstract and biography should be promptly
available on 3.5" floppy or via electronic transmission upon
selection). All papers submitted will become part of the Florida

You give the (initial) IP address and UDP port number as the arguments after


"write" for the OTUDP object, e.g., "otudp write www.cycling74.com7000".

Starting with OTUDP version 1.6 (which is available from
http://cnmat.CNMAT.Berkeley.EDU/Max) you can also send the message "host",
with IP address and UDP port number as arguments, to change the host to which
the object writes) on the fly.

You should also be able to change the port number from which "OTUDP read"
reads on the fly, but I haven't made that work.

!

It depends how you would like to go from here to there.
An easy way is to use two cycle objects, one with a sine (which means set
0.75 for the phase) and one with a sawtooth (which you need to put in the
first 512 memory locations of a buffer). Feed both with the phase in the
right inlet.
add a audio-multiply at the output of both, feeding the first with 1-x and
the second with x. x should be between 0 and 1 and is the percentage of
distortion.
then add the output of the two multipliers and you are done.

But probably you want to have a closer look at waveshaping etc.
