Actually nothing can connect to it as there is no DNS entry for
heinous.isca.uiowa.edu on isca.uiowa.edu's DNS server.

Heinous.isca.uiowa.edu is no more. Use serial.music.uiowa.edu instead, please. Still requires Fetch (rather than Netscape).
That site will also move in a while; I'll send e-mail when it does. We're trying to find an ISP that has a sufficiently high bandwidth/$ ratio. :) At that time, we'll also change operating systems, meaning that Netscape will start working with the site (at last!)

GrainMaker 2.0 (new and improved version) can be found at the
following sites:
ftp://ftp.ircam.fr/pub/forumnet/max/sound/68k
ftp://serial.music.uiowa.edu/pub/upload
ftp://ftp.media.mit.edu/incoming
All three sites contain version 2.0 which includes several new
features including random transposition possibilities and the
ability to write the file directly to disk. It is also much more
stable than the old version which relied on a less than tolerant MAX
object. I have used this version to create score files in excess
of 25 MB with no crashing and burning!!
A new manual is located at the uiowa and mit sites but cannot be
found at ircam yet. It is also possible that the GrainMaker files
have been moved from the uiowa upload and mit incoming directories
but they should be there on the servers.
Happy Granulating!

We had minimal success using 'hrtfer., We are running csound on an SGI
Indy 2 running IRIX5.3. It was not posible to run it in 'real-time.'
What came out was a vague notion of the real sound. When not in realtime
the sound was fine but we could only get the sound to go behind us(using
headphones).
I used SOUNDHACK HRTF a few years ago and it seemed to work okay,
although I don't remember if that was in real-time or not. Again it only
works well when wearing headphones.
I hope I helped, John Beahan

Hi Hans,
I didn't try your example, but there was a paper in the ICMC proceedings of
Hong Kong (1996) on page 222-223, Kai Lassfolk: Simulation of tube audio
circuits.
Another article may be interesting, even if the is no real tube simulation:
Charles R. Sullivan: Extending the Karplus-Strong Algorithm to synthesize
electric guitar timbres with distortion and feedback, Computer Music
Journal, vol. 14, no. 3, pp. 26-37.

To use *.orc files (I better should have named them *.iif -
instrument include files) as instrument input is a little tricky.
Csound expects functions for lots of instruments to be included
in the header section of your resulting score file. That means
that all functions used by your *.orc instruments should be
defined in a 'midi2cs.hdr' file in Midi2Cs's home directory. Do
not forget to enable 'scoreheader'-reading of the *.hdr file by
editing the global 'midi2cs.pro'-file. e.g.:
scoreheader c:\csound\midi2cs.hdr ; file to be included into
scorefile (readonly)
My current midi2cs.hdr looks like Russel Pinkston's (I think he
was it but I won't swear) header section defined for lots of
instruments in his tutorials:
; Simple Sine Function
f01 0 512 10 1
; Ramp
f02 0 513 7 0 512 1
; Exponential rise
f03 0 513 5 .001 512 1
; Quarter Sine Wave in 128 locs + extended guard point
f04 0 129 9 .25 1 0
; Quarter Cosine
f05 0 129 9 .25 1 90
; Triangular Wave
f06 0 512 10 1 0 .111 0 .04 0 .02
0 .012
; Sawtooth Wave
f07 0 512 10 1 .5 .3 .25 .2 .167 .14
.125 .111
; Square Wave
f08 0 512 10 1 0 .3 0 .2 0 .14
0 .111
; Narrow Pulse
f09 0 512 10 1 1 1 1 .7 .5 .3 .1
; Exponential rise and decay
f10 0 513 5 .1 32 1 480 .01
The string instrument I used for testing looks like the
following. Please do not add instr or out/outs lines. 'instr' and
'out/outs' lines are added automatically by Midi2Cs as needed
depending on mono/stereo settings in the 'midi2cs.pro' file and
automatic instrument numbering.

You might have noticed that there's a par/endpar section in the
instrument to specify parameters for automatic use with Midi2Cs.
Parameters should be exactly as to be set in 'midi2cs.pro' and
described in the manual. These settings have a higher priority
than any midi2cs.pro file. It's not tested to death, so if there
are any errors, please tell me, so that I am able to correct
them. I am also interested in receiving intruments edited for the
use with Midi2Cs. I'd like to publish Csound instruments working
with the new GM features of Midi2Cs 0.95 them on a new web page.

Dear Csounders,
I had a question concerning using Csound instruments with
Midi2Cs 0.95's GM feature and decided not only to tell it the
person who asked. It might be of general interest if I did
leave something out that wasn't obvious in the manual ...
Enjoy!

GM supported - 'midi2cs.gmi' (General Midi Instrument) config file
A new file 'midi2cs.gmi' will be created in the config files's
directory the first time you start Midi2Cs 0.95. This file is the
new General Midi Instrument's configuration file. It looks like
this:
; MIDI2CS - General Midi instrument table
; Program Number - Instrument (WAV, AIFF or ORC file)
000 "" ;Acoustic Grand
001 "" ;Bright Acoustic
002 "d:\studio\samples\gm\acpiac3.aif" ;Electric Grand
003 "" ;Honky-Tonk
004 "" ;Electric Piano 1
005 "" ;Electric Piano 2
006 "" ;Harpichord
007 "" ;Clav
008 "" ;Celesta 009
...
048 "d:\studio\csounds\strings\strings.orc" ;String
Ensemble 1
...
Just add your own *.aif, *.wav, *.orc (see Midi2Cs's manual)
files to design your own individual General Midi Instrument set.
Next time you run a conversion of a MIDIfile the instruments of
this table will be used as presets for all tracks in your
MIDIfile that contain GM program changes (the first change will
be taken).

Be warned, it's still beta, and the documentation is not up to date.
That should not prevent you from using the software with some success.
The biggest difference between the Mac version and the Unix documentation
is the removal of realtime control interface objects, so any reference to
that sort of functionality does not apply to the Mac.
I'd like to hear any sort of comments. We will try to fix and improve as
much as we can for a "less beta" release near the beginning of september.
At around the same time, a PC/Win95 beta should hit the FTP server.

KNOWN ISSUES WITH THE MAC VERSION:
This is BETA software. It works, but still has to be cleaned up. It's a
port from Unix (SGI), and even if the underlying programming language is
platform-independant, MacOS and Unix are quite different worlds
(especially in how programs communicate together). Everything seems
functional, but we are still walking on thin ice.
This package requires RAM! You need to run at the same time Csound (aka
"perf", a component of Mills Csound for PowerMac), Cecilia (and the
underlying Tool Command Language) and possibly Netscape (or something
simimar in function, for the docs). Also, TCL is not known as an
efficient processing language, so at times on non 604e machines things
may feel somewhat slowish. Cybil scripts may take a while to compile,
and the graphic updates may get sluggish when there is a large number of
breakpoints (say, over 400) in graph interfaces. The "bare minimal"
hardware would be a PPC processor with 16megs of RAM while the "nice
setup" would be a 604 with 24megs or more. My own machine, which is
working very well, is a 604e running at 180Mhz with 80megs of RAM and
OS7.6.1.
A bug with the folder selection mecanism means we cannot use the Mac file
browser to choose a directory. This is a problem with TCL, and Sun
should come up with a fix sooner or later... So for now, directory paths
must be entered by hand (but fortunately the browser works for file
paths).
There seems to be something wrong in the AppleEvent mechanism, where in
*some* hardware/software configurations, helper applications do not
launch properly (for example, Netscape does not launch when help is
reqested). If this happens to you, launch Netscape by hand, and try
again. Whatever the outcome, send some email so we can identify the
cause of that problem. Before thinking you are victim of this, make sure
to specify your helpers in the Preferences. Cecilia comes with
"pre-configured" helpers, which may not be what you are using.
The documentation does not yet cover the changes made to the Macintosh
version, so things like "Alt" modifier keys, Unix paths, "exec" and
"pipe" references have not been removed. Likewise, the new
functionalities of the Mac version have not been added. However, most of
the changes should be either explicit or invisible, so it should handle
OK. On a similar note, the builtin csound reference is not the latest
latest one.
Not all the dialogs have been updated to the Mac look and feel, so
occasionally you will stumble on a "dark" X/Motif-looking window...
Similarily, not all of the key/mouse bindings have been trapped to
Mac-wise equivalent. Some keyboard equivalents may not work, and some
equivalents may not be advertised. More importantly, the Mac has only a
single mouse button, whereas the original Cecilia platform (SGI) had
three. All the functionality has been reduced and purified to the single
button design, but some things may not be totally fluid yet. If you find
any of these, a tiny report would be appreciated.
The Cecilia files (prefs, modules, graphs and snapshots) still have bland
generic icons. This might be taken care of at some point...
