I downloaded the .tar.gz file and reconstituted the contents under 
Windows 95 using WinZip 
(http://tucows.rucc.net.au/awinzip/wztucow0.htm)

I have not looked at it in detail, but the index is especially 
welcome!

I understand that John Fitch's next release will include my ugrw1 and 
ugrw2 ugens, details of which are below.

Assuming that this goes ahead, how can I contribute documentation of 
these to the new manual project?  

Could you explain what software you are using to generate the HTML, 
RTF, ASCII and Postscript versions of the manual?

I can use a Mac if this is required, but would be happier to do it
under Win3.1/95 or Linux.

- Robin


ugrw1
-----

1 - Table write ugen - for writing directly into function tables at i
    k or a rates - with i or k rate control of the table number. (See
    tabread.doc for krate control of table reading ugens in my ugens2.c.)  

2 - Ugens for manipulating data in tables: tablegpw, tableleng, 
    tablemix and tablecopy.

3 - Ugens for reading and writing to table locations sequentially 
    from a rate variables.

4 - Patching of i, k and a rate signals based on numbers generated at
    i or k rate.  This is called the "zak" system.

5 - Simple ugens to read the time elapsed since the start of the 
    piece or the initialisation of the instrument.  Could be mighty
    handy. Also intended to be a lasting part of Csound if people like
    them.

6 - Two ugens for printing k rate variables as numbers on the screen.
   

ugrw2
-----


1 - kport Like port, except the half time can be controlled at k
    rate.

2 - ktone, katone, kreson and kareson Like tone, atone, reson and 
    areson except:
    a - They work with k rate signals instead of a rate.
    b - For kreson and kareson, the default for iscl is 1.

3 - limit ilimit  These set upper and lower limits on i, k or a rate 
    variables.

Newbie question:
Are all orc's supposed to work with all (or different) scores? Or are the
scores generated specially for the orchestras?

I have some orchestras that just generate errors with any score I try.

The way I see it, every orchestra should work work with any score,
otherwise Csound doesn't make much sense.

I've been using a Pentium 133 for the last year or so, which is just a
little too slow for the kind of things I've been attempting with Csound.

I've been looking at published benchmarks in the magazines, and reading
between the lines it looks very much as if the vastly more expensive
Pentium Pro 200 is less than twice as fast for floating point work. While
obviously an improvement, I'm not convinced it's worth the extra outlay at
this stage.

Meanwhile, the new Klamath chips aren't going to be much faster. They run
at 233MHz, but the off-chip cache slows things down making the performance
roughly similar to the existing PPro200. 

So - does anyone out there use a Pentium Pro, of any flavour? How does it
compare to a Pentium for Csound work in the real world, away from Intel hype? 

Also - is it possible to optimise Csound for MMX?  

All observations gratefully received.

Thanks,

R.

Neither. Each orchestra uses a fixed number of parameters called pfields.
The number of pfields in the orc must match the number of pfields in the
score. Otherwise you get errors.

Orcs also assume implicitly that the numbers passed by pfields are in a
certain range. For example, if a pfield is being used for panning then the
range is usually 0 - 1. A number outside this range may choke the orc and
make it complain.

As long as you understand this and arrange your scores to suit, you can
create any number of scores for the same orc.

It often helps to understand the basics before jumping to any conclusions. :)
