This is a variation on the well known "Good Times" hoax. Viruses cannot
be transmitted via email. There has been some interesting debates about
this hoax which dates back to ~1994. Some say it *is* a virus of a new
kind: ie: the virus is the message itself, propagating through the
well-intentioned warnings that self-multiply over e-mail, discussion
groups etc...

A word on viruses: While they do exist, the ones that do damage are
*extremely* rare. For the better part, they constitute an urban myth
that keeps the anti-virus industry healthy and profitable. In 25 years
of daily computing in small and large computer instalations, I have yet
to experience a damage inducing virus.

For the final word on the hoax, see:

Not again ;-)

What is described is technically impossible. The message you send is the
'virus' in itself and you just propagated it violently ;-). Read the
message using that point of view, you'll see, you'll have a "good time".

Cheers,

Not that I want to turn this into a virus discussion list, but in less than a year
of daily computer support in a corporate environment I have seen a good lot
of damage induction by several nasty viruses, notably Michelangelo, Monkey,
and Form. The infamous "Word Macro Virus" family is quite pernicious as well:
though not technically destructive, in ubiquity it is capable of producing a
sizable collective headache.

And as for viruses-by-mail: the greatest dangers are those cute little attachments
people distribute to their friends--little executables that make animals run around your
screen or wish you a merry christmas. Left unlaunched/undetached they should
be harmless, but who can resist trying them out?

I am currently working on a virus to include in Csound v3.46 that will force all
Csound composers to state in no uncertain terms their position on the moral
value of MIDI. The results will be compiled via automatic email, rendered aurally,
and submitted to television stations worldwide as a substitute for the test pattern
soundtrack.

how do i set duration parameter in i statement in mm (metronome) units
assigned by tempo?
example. starting with:

instr	1
amp	linseg 	0,8,20000,8,0,8,15000,8,0
asig	oscil	amp,cpspch(p5),p4
out	asig
endin

t	0	60
f1	0	8192	10	1
i1	0	32	  	1 	6.06
e

figure ok. here it is: p108 manual. let's just double tempo thusly:

t	0	120 blah blah blah

but what i hear is just half of original linseg:

instr	1
amp	linseg 	0,8,20000,8,0
asig	oscil	amp,cpspch(p5),p4
out	asig
endin

tried putting t statement everywhere. then tried stick a t in front of dur
to see if it would notice. nope.

Also: can i set a different tempo in sco for each i statement?

working on exhaustive kinderfaq.

thanks again!

unlimited numbers of stages, however, I think you're going to have to go
with some form of table look up and reinitialization. In other words, use
gen 2 to fill as large a table as you need with your envelope segment data,
in the format val1 dur1 val2 dur2 val3 dur3 val4 dur4...etc.<

The idea is to set up your linseg
in terms of the duration of the note:

instr 1
	idur	init	p3
	ivol	init	p4
	ifront	init	.1
	iback	init	idur - ifront

	kenv	linseg	0, ifront, ivol, iback, 0

	...
	...
	...

//

That sort of thing.

Hi all,

A work of mine for percussion and tape is being premiered in the Boston
area. The tape part was (surprise, surprise) created with Csound. HUGE
Thanks to the folks at Mills (and all you other Csound fiends who keep this
code available and working) for their work on Csound for the Mac and for
the nifty score generator that I used extensively in this piece. The
concert should be a lot of fun---hope you Boston-area folks can make it!

Not that I want to turn this into a virus discussion list, but in less than a year
of daily computer support in a corporate environment I have seen a good lot
of damage induction by several nasty viruses, notably Michelangelo, Monkey,
and Form. The infamous "Word Macro Virus" family is quite pernicious as well:
though not technically destructive, in ubiquity it is capable of producing a
sizable collective headache.

And as for viruses-by-mail: the greatest dangers are those cute little attachments
people distribute to their friends--little executables that make animals run around your
screen or wish you a merry christmas. Left unlaunched/undetached they should
be harmless, but who can resist trying them out?

I am currently working on a virus to include in Csound v3.46 that will force all
Csound composers to state in no uncertain terms their position on the moral
value of MIDI. The results will be compiled via automatic email, rendered aurally,
and submitted to television stations worldwide as a substitute for the test pattern
soundtrack.

Much like the Keyboard Magazine article.
