| Hi All
We are looking at doing non clasical shaped filtering, i.e. multi
pole arbituary filtering.
Also if possible how would it do this in real time.
Thanks for the help

See filter2, kfilter2, zfilter2 in the Csound HTML manual for the most
general method to do arbitrary filters. For reasonable filter sizes they
will run in real time. There are lots of other ways, too. Check out lpread,
lpreson, lfreson in the Csound manual. Also check out Russell Pinkston's
orc's and sco's. That should at least get you started.

Hi,
I was trying to compile some files and I am getting a PMAX warning in
during compilation and my resultant file has alot clips in the sound. If
any one could please tell me what can be done about this and exactly
what PMAX is I would greatly appreciate it. Thanks for all your time.

Some of us csound users/hackers, (mostly) working on Linux platforms, have
decided to use some of the source control tools (cvs) in maintaining the
linux sources for csound. In this development tree, we intend to track
fixes and addition to the canonical sources, and add bug fixes, new opcodes
and functionalities. Likewise, we intend to submit appropriate bugfixes
and enhancements back to the maintainer of the canonical source.
The development tree, known as the csound CVS repository,
can also be accessed anonymously for reading (instructions below).
This way, all interested parties can have access to the latest snapshot
sources and also any intermediate linux release. We will continue to
maintain binary and source distributions in the usual places,
but we plan to be able to closely share the development process with
anybody interested.
Instructions to access the cvs repository (access has been tested
successefully with cvs client/server version 1.9.28, which can be found at
www.cyclic.com):

Csound for linux version 3.482.1a is available from the AIMI site in Italy
ftp://musart.dist.unige.it/pub/CSOUND and will shortly be mirrored by
Dave Phillips at his repository ftp://mustec.bgsu.edu/pub/linux.
In addition to the features of the canonical 3.482 version, this version
contains:
- fixes for diskin bugs [Nicola Bernardini]
- fixes for orchestra parser bugs [Nicola Bernardini and Robin Whittle]
- glibc patches [Robin Whittle and Damien Miller]
- standard autoconf configuration script [Nicola Bernardini and Damien Miller]
(you know, all the ./configure business...)
- new random generator with 31 bit Park Miller Pseudo Random Number
Generator - bipolar xbunirand family opcodes added [Robin Whittle]
Standard configuration allows dynamic linking of executables with
small footprint. Versions with and without X11 are also available
and static, debugging and profiling versions can be built easily
out of the distributed sources.
Enjoy,
Nicola

PMAX is the maximum number of parameter fields allowed and is currently set to 150.
The only solution is to reduce your amount of pfields to less than 150 or to
recompile CSound with a higher PMAX.
I had this problem and ask the same question to the list.
J.P Fitch said he is working on the subject in order to make it flexible.

My latest piece in Csound has annoying subtle distortion sometimes however
the signal is **never** out of range !!
I checked the range in a GUI sample editor and also Csound never said
during
the performance that there was even a single out of range sample.
anyone ?

I know that order of the standard Butterworth filter in Csound is 2, but I
want a
higher (like 6th or 8th...) order Butterworth.....Does it exist or how can
it be
created ???
I read something in the manual about a filter that can be filled in with
custom values
in its "coefficients", but that's a little way out of my knowledge on
digital sound theory..
So a little advice is wanted as I have not a clue how to use those filter
values/poles/coefficients and all that..
David.
