What happened to the pub/dream/newest repository? why is 3.47 out of
the repository and exists only in binary form (at least as far
as I know)?

There's a piece by James Tenney called "For Ann (Rising)" that's on his
Selected Works 1961-1969. This is based on an algorithm that's very
similar to a shepard tone. The version of this piece was regenerated in
Csound by Tom Erbe at Cal Arts according to Tenney's specifications. For
more information on this CD see:

Version 3.47 is not yet ready. However as it has rather a large
number of changes I sought assistance in finding bugs. So as anyone
using it was aware that it was not the latest version I gave it a Beta
name and placed in the platforms directory tree as it is not the
newest -- unless you wish to run any old bugware from my fingers!
When it is ready I will release binaries and sources. I have for
rather a long time now (since versions 2 at least) I have been trying
to reduce the number of variant systems. The reason I placed a new
version of teh beta is that I fixed a serious bug in cross2, and a
silly error in cpsxpch. I still have one problem in score reading
which I wish to investigate. Today I removed some tracing from
sndwarp as I am now sure it is OK. If all goes well I reckon it will
be available about the end of this month. I am also hoping that those
hardworking folk who look after Linux, Macintosh Power PC, and
possibly Atari will be able to release systems at about the same time.

Just wondering if anyone has any comments on the Nyquist blitz in the
current issue of Computer Music Journal. Dannenberg makes many explicit
comparisons between Nyquist and the Music N languages. I downloaded the
Nyquist manual and run-time--as a non-programmer, I wonder whether the
gains from Nyquist (integrated score, "intelligent environment," table-less
sound creation, etc.) compensate for the need to learn Lisp as well as
Nyquist.

The instrument number is the first parameter in the score
statement, so you can get it inside the instrument from the
parameter "p1". (I hope, don't know when instr is invoked from MIDI)

You'll find code for all of Csound at either of
ftp://ftp.maths.bath.ac.uk/pub/dream/
ftp://ftp.musique.umontreal.ca/pub/mirrors/dream
in file /newest/csound_new.zip
(this is v3.46 which is the current one, 3.47 is due Real Soon).
The current binary (with nlfilt opcode) is in directory
../platforms/mac/
There is also a mac version at Mills, but I'm not sure if they
have any 68k version, or are just doing PPC.
The nlfilt algo is given in docs as:
ar nlfilt ain, ka, kb, kd, kC, kL
Implements the filter Y{n} = a Y{n-1} + b Y{n-2} + d Y^2{n-L} + X{n} - C

Hi,
ACCCID (amsterdam examples) has three examples of Shepard
notes with good explanations. See \02\02_44_*.*
All are based on an instrument by Risset. It's also in the
common Csound collection, viz Endless.* and risset4.*
When I first heard of this, the teacher mentioned using
some bell shape for amplitude as if this was integral to
the proper effect. And so it seems; a formula in Risset's
original instrument is given as:
exp(-4.8283*(1-cos(2*pi*(x-255.5)/511)))
This is generated separately by an orchestra in the
ACCCID example.
Those who don't have the ACCCI collection should definitely
get it from
http://mars.let.uva.nl/gather/accci/download.html
cheers,

I have not yet had a chance to try Nyquist, though I am very interested
in it. The question seems to me to come down to the 'tool v task' issue.
If the task is primarily to construct sounds, then Csound/MusicN will
do the job very nicely. If the goal is algorithmic composition, (including
sound manipulation, presumably), for which Csound offers no direct support
(hence the development of score-generation tools), then Nyquist would seem
to be the more natural choice.

I have constructed Beta tests for 3.47 running on Windows and DOS.
They are available as
pub/dream/platforms/pc/csound_beta.zip
and
pub/dream/platforms/pc/winsound_beta.zip
on ftp.maths.bath.ac.uk
I know of one problem with score reading, and the MIDI output has not
been tested on any platform. I have also replaced the Mac betas with
a slight revision (only diagnostics). At present the Mac68K code does
not have complete MIDI output; I need to read some manuals first.
