Hum.... there was a classical off-by-one error in linseg, which led to
stupid overshoots etc. I now have a version which looks correct.
I am still rather uncertain is the error is in expseg as well -- I
think it is but for totally other reasons it does not show.
So, expect a new version soon! Anyone using source who wants more
information, mail me.

True, but in practice carefully hand-optimized code turns
often out to be hard to maintain and thus tends to lead to
secondary inefficiencies.

It might be worthwhile, given the differences, to upload a number of
compiled versions (or the fastest one if that can be established) for
those who do not compile their own Csound and have to use the executable
that is made available at the Bath ftp site. This would then be in
addition to the one placed there by John ffitch. Same perhaps for other
Csound flavors.
I'm using Csound on Windows and I for one had no idea that the Intel C
compiler would give much better results than MSVC. I suppose similar
observations hold for Csound for other OSs. I usually don't compile
Csound and just grab the executable, so contributions from people who
really know about building software and compilers are / would be greatly
appreciated.

I have a Celeron 300A w/ Abit BH6 motherboard, overclocked to 464Mhz.
76 oscillators
163 oscillators
852 oscillators
It's interesting that my osc/Mhz ratio is higher. The Celeron
has it's L2 cache on die and running at the same speed as the
processor.
Not bad for a mb/cpu combo that only cost $180.

You might try -m686 or even -march=686. You're compiling
386-optimized code. The first gives PII optimized, and the second
uses PII opcodes. You might also want to try -O9 (if you're using
egcs) since this may allow even more optimization. Also, optimizing
for size instead of speed may make things faster; using sine and
cosine could be faster (!) than a lookup table if the table's big ---
memory is *slow* so if you're short of cache, and Pentia have good
floating point.

Let me know if it helps... Not that thisi is especially relevant to
the original poster's question.

Problem is csound doesn't recognize program changes (message
type 0xcN, where N is the channel number). So, in order to
get MIDI files to drive csound you'll have to manually remove
these messages and add their delta times to the delta times
of previous non-program-change messages.
Or go fix the csound sources. :)
Attached you will find the test material: midiin.{orc,sco}
and {no,}progch.mid
Then run
csound -F noprogch.mid -o dac mididin.{orc,sco}

Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Sender: owner-csound-outgoing@maths.ex.ac.uk
Precedence: bulk
Csounders,
I have placed some new examples of my microtonal music on MP3.com. For
those interested in the use of Csound in a musical
context, you can listen to RealAudio snippets or MP3 compressed versions
of the files. All were created with Csound and some sample files from a
variety of sources. The site is http://www.mp3.com/PrentRodgers . The
source code (macro files and Csound .sco and .orc) are available at my
personal web site: http://pws.prserv.net/Music1 . The source code goes
through a macro-processor I wrote to simplify composition using
microtonal scales and complex rhythms, with a healthy dose of
indeterminancy. It produces .sco files, which I then send directly
into Csound sample based orchestra.
The new songs are:
- Speaking into the Air, a jazzy percussive piece with a simple
theme and challenging modulations around the 11 limit tonality diamond.
The piece stays in an identity for a random number of measures, and
wanders some more.
- In the Tongues of Men and Angels, which uses only the tones of
Partch's Incipient Tonality Diamond, which is limited to the 5 limit.
The piece uses only 6 tones at a time, which I call A-, C, E, F, G,
which is kind of like an A minor, without a B; and Ab, C, E--, F, G,
which is like an Ab major, again without the Bb.
@ Incipient tonality diamond with 1:1 set to C

Which unzipper are you using? I found that one called
Powerzip consistently does the same thing. I just got
a different unzipper. BTW I haven't tried unzipping
the new version of csound yet.

Dear John and Csounders
Had no troubles loading in the New one
In your notes you did not mention that it works about 3x as Fast!!!
I am running it on a clunky ibm cloney and minute and a half pieces were
previously a "run to the store or shower while" affair
Is this Just a pleasant Bonus for Winsound or is it across the board?
Beautiful regardless
Thanks

I have a PentiumII/350. My results were _very_ dependent of the
compiler switches (egcs-2.91.66):
-O3 -mpentium : 650 oscillators
-O3 : 700 oscillators
-O3 -funroll-loops : 890 oscillators
-O3 -fomit-frame-pointer -funroll-loops : 1036 oscillators (Daddy-oh!!!!!!!!)
After that, I will recompile my csound with these switches...

Whoops.
I _must_ have confused my versions of oscillates.c ... the one I thought
was Ed's is not the same as his message at all. I should have checked
that before posting.
I just re-copied Ed's code into a new file, compiled it with egcs
-m486 -ffast-math -funroll-all-loops, and it's running right now, over
400 oscillators and counting ... no glitches with X and emacs running at
the same time.
Final score: 720 oscillators, daddy-oh!
gcc with the same flags scores 690 oscillators.
Csound doesn't fare nearly so well. Compiled with gcc -O2 (at the
moment, due to a buggy .config file, I can't compile it with anything
else), I get 200 super-simple oscillators from this orc. ( I get about
160 if I use oscili instead of oscil, and only about 40 if I use
oscil3).
I can increase the performance with the -b flag: best for me seems to be
-b 4096, or -b 2048, which both get about 220 oscils. Even down at -b
256 I can get up to 200 oscils, which is pretty low latency for realtime
MIDI. I think I can say that small buffer sizes work better on this
machine than they did on a Pentium 133.
; begin orc
sr = 44100
kr = 2205
ksmps = 20
nchnls = 1
instr 1
ipitch = p5 + 200
a1 oscil p4, ipitch, 1
out a1
print p5 ; this tells us how many oscils.
