Try Gabriel Maldonado's version of CSound, which you can download at www
.agora.stm.it/G.Maldonado/home.htm. It's got all the new opcodes, as well
as some real-time MIDI stuff specific to that version.
As for the field problem, it's most likely because the example is in mono
and you're trying to compile in stereo, which takes more fields for some of
the opcodes. This isn't well-documented, and it took me a bit to figure it
out when I first saw it. Hope this helps.

Has anyone hit problems compiling Csound under Visual C++ V.5?
On compiling the file lptrkfns.c I hit an Internal Compiler Error, which
seems to relate to the floating-point optimiser. A get-around is to go
to the Code-Generation part of the Setting Dialogs, and use Custom settings
rather than the blanket 'Optimize for Speed'.
Microsoft claim a 35% increase in f/p performance under the new compiler, which
is pretty impressive, if it is safe.
More insidiously, when compiling the standard CARL implementation of the
Phase Vocoder (our CDP port of the original Fortran code to C), the
compilation completed normally, but pvoc generated an obviously incorrect
output. Changing the Settings as described above restored pvoc to correct
operation.
This is obviously a worry, as it means that a Release compile cannot be
guaranteed to be correct. I have never had a problem with VC++ V.4.

VC++5 changes the floating point unit to use less resolution it appears.
In the 3DFX 3D chip programming newsgroups they talk about how VC++5
reduces Floating point bit resolution to something like 24bits and has to be
fpu has to manualy be told to use more resolution in assembly code or
by some other means.
This is just speculation but it appears that some 3D programmers have
are getting the same not so accurate results and other float related problems.

Subject: How Client's Sales Doubled...
Sender: owner-csound-outgoing@maths.ex.ac.uk
Precedence: bulk
This is a one time Announcement only.
How Client's Online Sales Doubled in Four Weeks -
by opening four new locations for their business..
and you can too...we make it easy, affordable and
guaranteed.
Recent Letter received from Client:
"We wish to take a moment and thank you all for your
fine on line support, encouragement you gave us ....
Our sales have DOUBLED since coming on board with you
a month ago..."
SEVEN STEPS TO SUCCESS PLAN:
1. We mirror (copy) the first page of your existing
web site and install it in our 4 locations.
The total traffic to these sites is over 1.3 million
hits a month.
2. We link back to the rest of your pages. Your
current web pages are not changed in any way.
3. You are assigned 4 new URL's (http://) addresses.
4. We give you the http:// of a site to fill out
a form once for each of your new addresses. This
is automated software that will put each address
on 130 different search engines/directories.
This gives you immediately over 500 new listings.
5. Your 4 new locations are not only widely advertised
individually, you also take advantage of the
"accidental shopper" - shoppers who were not looking
for you to begin with.
6. Its just common sense. Who becomes more visible,
you with a total of five locations, or someone who
just has one. We took the concept of the offline
shopping centers that spread from town to town, and
have applied this to the Internet. A business with
a chain of five locations is serious about doing
business. This is the way many new chains were
built and brand names established.
7. Plus, right now, we are still offering summer rates.
** All 4 Locations - just $275, **
40% off regular rates.
Offer ends July 31st
Includes all set up and one year's rent
OUR GUARANTEE: You must double your money in gross
sales, or you get ANOTHER YEAR FREE...
Just e-mail back for full no-obligation
details - Hit reply and type DETAILS in subject.

Hello there,
just wanted to see if anyone knew of csound instrument code for
pitch shift and/or frequency shift. I know that some of csound compilations
offer the pitch function as pre-compiled ugen, or via the pvc
pre-analysis. I however wanted to create "from scratch" those things (i.e.
pitch and freq shift algs...)
I probably would opt for the "built" in functions but Csound on PPC
(Mac) doesn't have a non-pre-analysed pitch shift compiled (at least I am
not aware of such). Also, there is a case of frequency shift effect which
is again - different to pitch shift alg.
Well stay cool - Leon.
