| Looks OK. You should be able to run the DOS (csound_new) version on a 386.
Try running as
csound -v -o www.wav -W www.orc www.sco
and send me the output. That might give a clue.

I think I have moved copies to the server, and the documentation. I
am still suffering from a hardware failure, but I think I have found
an alternative transfer route.
So, I have retransferred all the files, including the documentation

In wich C variant is the canonical sourcecode from Csound 3.47 (january 98)
written ?
Symantec, Borland, Watcom, MS ?
Is there any documentation of the procedures and functions of the Csound
sourcecode module ?
Is there any documentation the elaborate explains how to write your own
Csound instruments/modules
and recompile it properly ?

A question that has nothing to do with the wonderful musical explorations
of you all, dear people,
but has anyone of you knowledge of how to get rid of that F****** junk mail
??
My Csound mail collection suffers from junk messages mixed among the useful
messages.
Is it possible to get rid of it for free ?

First decide what operating system you run!
There are 3 main possibilities, DOS, Windows or Linux.
Then decide which ftp server is closest, Montreal or Bath.
If you run DOS only, take the file
csound_new.zip
If you run Windows95 or Windows3.x and have Win32s, take the file
csound_win.zip
If you run Linux, then you need to take the file for Linux -- but I am
afraid that I cannot remember what it is called. We are expecting an
update within days anyway.
If DOS or Windows, you then need to unpack with UNZIP of PKUNZIP, and
there you are.
Or have I misunderstood teh question?

Glad to hear about the new version release! Are there any plans to
release a NeXTstep port of version 3.47 and does anybody know if the
binary will also run in Rhapsody. I was reading a little about Rhapsody
over the holidays and it looks like it will be a nice OS for both PPC and
Pentium PC platforms. Maybe someone out there with a PPC and Rhapsody
could port the 603E binary too (if the Mac pre-release is even
available). I noticed that pub/dream has a NeXTstep binary of v3.46 but
is that for the original cube or the later PC version of NeXTstep?
Since Rhapsody runs native Mac binaries in addition to NeXTstep, that may
be another alternative too....
Perhaps some of you that know more about this should speak up. Anyone?

How can i modify the pulse width of a pulse wave in Csound. I'd

Hi, all!
Can anyone, please, explain to a begginer what's a nTh order
filter. i.e. like a 2nd order lowpass and what is a 12db/24db filter?
BTW, what's resonance and how i can implement this in csound?
This is the emphasis in the frequencies near the cutoff point?
And i presume that resonance and "Q" are the same thing, is this
correct?
Thanks in advance!

It is for the original (motorola68004processor) NeXT:
on the Intel platform , the NeXT midi driver A.P.I. changed extensively,
and I (or anybody else) have not taken enough time to fix the Midi
code in csound to be compliant with the new midi libs on Intel.
>Since Rhapsody runs native Mac binaries in addition to NeXTstep
I know some Rhapsody developers: perhaps we can get a compilation going
on their box. Yes: there will be O.S. emulation for Mac and old NeXT binaries.
I cannot recommend using such with Csound: I imagine the emulation
overhead would be greatly noticable. I will get an "Original NeXT" binary
built for 3.47 soon, and upload it. But what really needs to be done is
the prot to the Intel savvy NeXt midi code. Dang, I should blow off my
employers and their petty market driven needs, and take time to port
the 10 or so NeXT midi lines to the new A.P.I...boy , I miss being
an academic, where such activity would be supported. Any tenure-track openings
I havn't heard of, guys? Sigh.

Updated to cover version 3.47, as far as the documentation
goes. I'll be updating it quietly as new docs appear.
Get it from http://hem.passagen.se/rasmuse/Csound.htm

Hello,
Hopefully someone will correct any mistakes I make...
> Can anyone, please, explain to a begginer what's a nTh order
>filter. i.e. like a 2nd order lowpass and what is a 12db/24db filter?
The order of the filter corresponds to the order of the differential
equation which describes the filter. A first order filter has one pole and
has a roll of of 6 db/octave. Each order adds another 6 db. An Oberheim
Matrix has a 2-pole filter so the frequency response rolls off at 12
db/octave. A MiniMoog has a 4-pole filter that rolls off at 24 db/octave.
In other words frequencies one octave above the cut-off point would be
attenuated (reduced in volume) 24 db with a 4 pole filter. The frequency
response is the ratio of two polynomials
(a0+a1*x+a2*x^2...)/(b0+b1*x+b2*x^2...)
The biggest exponent on the polynomials is the same as the number of poles.
(I think the a's are called zeros and the b's are called poles actually
but lets not get too complicated here...)
Digital filters are a bit different. Instead of the differential equation
they are based on the difference equation. The frequency response is
(a0+a1*exp(-i*theta)+a2*exp(-i*2*theta)...)/(b0+b1*exp(-i*theta)+b2*exp(-i*2
*theta)...)
Which looks to me like the zero term is an offset, and each of the other
terms traces out a circle whose radius corresponds to the coefficient. The
first term would trace out a semi-circle as the frequency goes from 0 to
sr/2 (the Nyquist frequency) (theta goes from 0 to pi) The second term
would complete a full circle, the third term a circle and a half etc.
> BTW, what's resonance and how i can implement this in csound?
One of the things that give analog synthesizers their distinctive sound is
resonance. This is a boost or emphasis of frequencies at the cut-off
frequency. (well just before the frequency starts dropping.) In the case
of the Moog diode ladder filter the phase at the cut-off frequency is
shifted by 180 degrees and an inverted signal is fed back into the system
which results in the resonance. With digital filters things are a bit
different again. For some implementations review this lists archives and
for some simple examples:
http://www.werewolf.net/~hljmm/csound/
> This is the emphasis in the frequencies near the cutoff point?
Yes, see above.
> And i presume that resonance and "Q" are the same thing, is this
>correct?
Umm yes pretty much. (I think) Although I think Q is sometimes used to
describe the band-width of a band pass filter but that's sort of the same
thing.

I am having trouble using a midi keyboard to spawn
audible events. I have done this some time in the
past, but have recently attempted it again with
3.47 without success.
I am getting instrument triggers from the Midi
keyboard, but no sound with -odac or otherwise.
Here are the specifics:
Linux csound3.47 (no luck with generic source,
or Linux Specific binary from Dave Phillips).
Pentium 150, Soundblaster Midi, yada yada yada..
***orc***
sr = 44100
kr = 441
ksmps = 100
nchnls = 1
instr 1
ivol ampmidi 10000
ipitch cpsmidi
asig oscil ivol, ipitch, 1
print ivol, ipitch
out asig
endin
***sco***
f1 0 16384 10 1
f99 100 1024 10 1
***command line ***
csound -M/dev/midi0 -o dac orc sco
I believe that the instrument is getting the proper
signals, because the debugging 'print' statement that
I put into the orc yields output like:
MIT Csound: 3.44 (Jan 9 1997)
orch now loaded
displays suppressed
midi channel 1 using instr 1
audio buffered in 512 sample-frame blocks
hardware buffers set to 1024 bytes
writing 1024-byte blks of shorts to dac (WAV)
SECTION 1:
ftable 1:
new alloc for instr 1:
instr 1: ivol = 2656.250 ipitch = 1046.502
instr 1: ivol = 2656.250 ipitch = 1174.626
instr 1: ivol = 2343.750 ipitch = 1318.436
instr 1: ivol = 3906.250 ipitch = 1396.874
instr 1: ivol = 1953.125 ipitch = 1318.436
new alloc for instr 1:
instr 1: ivol = 2109.375 ipitch = 1174.626
instr 1: ivol = 2031.250 ipitch = 1046.502
instr 1: ivol = 2187.500 ipitch = 987.739
The pitch is right. The volume is right. The instrument
is clearly being triggered. Why no output?
Thanks,
Toby

After reading the message that I sent
in about version 3.47, I noticed that
the output that I had pasted into the
letter indicated that I was actually
running version 3.44.
I fixed my PATH and ran the same test
with version 3.47. I am afraid that
the new version made no difference in
sound output, and, adding insult to
injury, actually failed to show any
activity in the instrument at all via
the 'print' statement.

When experimenting in conditional processing,
use different tone colours for each logical
choice.
David used filters that sound too similar.
This results in not being able to discern
whether there are any logical decisions
being made. Here is a sco and orc
that allow you to hear the difference
between the two things being decided:
It may sound like a submarine, but you
can easily tell the difference between
conditional choices one and two.

In my humble opinion, the WGBRASS opcode is wrongly documented :
the 3.47 release notes features the wgbrass opcode as follows :
ar wgbrass kamp, kfreq, iatt, kvibf, kvamp, ifn[, iminfreq]
where ifn is the function table containing the shape for the vibrato
(kvibf).
After the ifn, the notes state an appearantly OPTIONAL minimal frequency
(iminfreq), well
actually iminfreq is NOT optional but compulsory and also the ifn and
iminfreq slots should be swapped
so the right wgbrass opcode looks like this :
ar wgbrass kamp, kfreq, iatt, kvibf, kvamp, iminfreq, ifn
I experimented with wgbrass (because I focus mainly on dronal textures)
but I could only get an awful high pitched burst of distorted sound (almost
blew up my speakers)...
anyobody ?
David.
