Thanks, Joerg; I'll try to check out your suggestion. I am sure the
Tandy 1000TL has an ancient version of DOS, perhaps (as I recall--I seem
to remember not being able to upgrade it) in ROM! Could this be a major
problem? Can anyone comment?

There is not really a "new" optional argument in pvoc, but the "ispecw"
argument, which did not work as described in the manual has been fixed
and now seems to do what it is supposed to do.

Hi all,
I've just been catching up on the latest versions of csound. I have  
just managed to compile 3.46, after a bit of fiddling.

The changes made to sread.c in the stof function DO NOT work on NS.  
I had to revert to the commented out section (glad that was left  
there). It compiled ok (before my patching), but complained about  
illegal number formats in score files.

The reason I was getting the latest version was to see if a  
particular score/orchestra sent to me by a student would work.  
Previously it complained with an indexing overflow error. It still  
does! From my cursory glance through the oload.c code I can't really  
understand what is going on, and I don't understand the role of the  
indx variable. Perhaps someone can explain those to me, with  
particular regard to the example (appended) which has the indexing  
overflow error.

Lastly, I would love to get the latest MIDI driver for NS/I  
integrated into Csound. Has anyone out there attempted this?

Thanks very much,

The new edition of the Dodge book is not out yet.
It will probably hit the shelves sometime in july, though
it could still be delayed some by the publisher,
so take that as "roughly" july.

Hi,

When fading out on my mixing desk i think the bass fades quicker
than the trebble. Is there an equation / rule for this?

A constant fade filter might be interesting.

Bye.

Hello CSounders!

We're expanding our facilities and were considering getting an SGI
workstation for, among other things, running CSound. However, I was
wondering if anybody here could inform me about what hardware/software
combinations they were using for audio I/O. We would love to have balanced
lines for analog I/O and also AES/EBU, preferably four-channel or more. The
idea is running the workstation directly to a mixer/amp as part of an
interconnecting set of sound design/composition workstations. Am I asking
for something impractical or inexistent? We were considering the new O2 or
maybe even an Octane computer...

Thanks for your help.

get an ordinary O2 or Octane with ADAT card.  This gives you 8 channels
ADAT, plus stereo AES/EBU, which you can route to whatever digital
equipment you want to.  Doug Cook's audio page has all the info on
both, the machine and the card, at

   http://reality.sgi.com/employees/cook/audio.apps/

The machines have stereo analog I/O, but it seems you are better off
with digital for your purposes.

Re software: I just tried the new SGI compilers on csound (vers. 3.46)
and got a good 30% performance improvement so far.  Ill post my benchmarks
set in the near future.


Hope this helps,


-Tobias

Take a look at an hearing curve and consider the lower hearing threshold in 
the base as compared to 3 kHz. Also look at the loudness curves as they 
changes with frequency.

> A constant fade filter might be interesting.

Hint: Do you recall those "loudness" buttons or pots on your old stereo?

Magnus

 G> 1) Where is the manual of new "FOG" opcode?
In Huddersfield.  As i said I was still waiting for a final tweak and
documentation, but I did not want to remove the code or to delay
getting all teh fixes out.

 G> 2) What are the bug fixes of "igoto"?
It was possible to have opcodes not initialised but still called at
k-rate.  If the initialisation involved creating structures this led
to general collapses.  This is now checked.

 G> 3) What are the improvements in "pvoc" and what is the new additional
 G> optional argument?
Richard Karpen has answered this

 G> 4) In what case "endin" statement had not noticed before the fix?
In the previous system omiitting teh endin opcode at the end of the
orchestra led to rather obscure errors at performance time.
