Subject: Re: subdividing an integer?

<fontfamily><param>Geneva</param>Hey Sukandar,


</fontfamily>Your patch works fine except I want to be able to specify
how many sub-divisions there are, so it is not fixed at 3
sub-divisions. The number of sub-divisions should be a variable.


Of course this variable should only be allowed to be as large as the
integer that I am trying to sub-divide and not larger.


Regards,


Steve

I recently had to re-format my hard drive and found that when I re-installed my
scanner softwareI started to get a crackle every 15 seconds or so out my PB
output...same software, same computer, new noise....I created a seperate
extensions file for when I need to scan, and keep it off when I do music. You
may look for something like that in your system...

Good luck!

Subject: trigger puts spaces in symbols!

Any suggestions on how to strip a leading space in a message? I have made
the unfortunate realization that the "trigger" object puts a space before
any symbol that begins with an integer.
For example, sending the message "1 1 10" into "t b s" will give me " 1 1
10". Yes, there is a space character in there. Yes, this totally hoses
everything--the message is directed to "route," which errors "route does
not understand '' "
Please help!!! My brain (and patch) is stuck!

Peter.

I don't have a solution off hand, and the patch Sukandar sent may well
work (haven't tried it yet). I just mention that the problem of
partitioning has been handled in some mathematical and (!) musical
literature, and is pretty well understood. So, cracking a book might give


you some more insights. If you're interested in pointers, I'd suggest
[Babbitt, Milton. 1973-74. Since Schoenberg. PNM 12 (1-2):3-28.] as a
starter.

Briefly squinting at Sukandar's solution, I'm wondering if an approach
that used Peter Elsea's LObjects might not work a bit more smoothly. All
those Uzis make me a little nervous, but maybe that's just me.

Sorry not to have a more concrete contribution. This is one of those
things that I've thought a bit about without ever having had
time/motivation to sit down and find a solution.


Cheers,

Peter

Hi,

I'm working on a sound/video installation piece and are thinking about

MAX MSP.. =

does anyone know about any videotracking software wich could be useful?

Do you want a max patch, or would something in c/perl/basic/whatever
work for you?

Prepend the '1 1 10' with any other symbol, then strip it off after outpu=
t.
i.e. run '1 1 10' into a prepend symbol, then from the 's'
output of the trigger, run it through a route symbol. You get back the
'1 1 10' without a space.

Can someone tell me where in the MAX archives is the patch someone did for

hi all,
i´ve tried the Opcodes sonic port optical with OS9
the result was very noisy, not in time and maybe a destroyed pair of

I´ve asked at opcodes manny times about the release date of the mac
drivers for the port - no answer.
so i gave it back end of november.
does anybody know about any usb-audioport for powerbooks?

Don't use the Digi direct I/O driver, use the direct I/O included with MSP=

instead.
So, with adac~ 1 2 3 4 5 6 7 8,you have all 8 outs of your 882.

Hope this helps.

Subject: crusherX-Live! real-time fog synthesizer


To everybody who is interested in sound software:

I want to introduce my new shareware programm witch you can use to
create innovative electronical sounds and rhythms:

****************************************
* crusherX-Live 1.22*
**
* real-time fog soundsynthesis for PCs *
**
**
* buero </stelkens>, J. Stelkens*
* info@stelkens.de*
**
* Download: http://www.crusher-x.de*
****************************************

Concept

crusher-X is a shareware program whose powerful fog synthesis algorithm
enables you to synthesize very complex and cool waves. Based on
traditional granular synthesis, crusher-X can be used as a synthesizer
or as a versatile effects unit. You can create sounds with the internal
oscillators or external files as well as input real-time stereo
soundfiles. Internal feedback loops allow self-oscillation within
crusher-X!

Algorithm

The new crusher-X algorithm (we call it fog synthesis) is based on the
traditional granular synthesis algorithm invented in the early 1950s. In
granular synthesis, short (e.g. 50 milliseconds) sound fragments, "the
grains," come from a fixed file buffer. The starting time, length and
silence between the grains can be modulated. More than one grain at a
time is possible, so you can create complex sounds "clouds" from a
single soundfile.

The most significant difference between granular and fog synthesis is
the floating sound buffer which allows real-time input and output. In
this floating buffer the grains are created. You can apply many unusual
parameters to the grains such as pitch, filter, pan, reverse, and limit
- all with a simple, flexible interface.

All parameters can be modulated by internal oscillator sources, whose
configuration can be saved as crusher-sheets. A feedback loop inside the
algorithm enables very complex and non-linear sound processing. Also, a
multiple Undo/Redo function permits nondestructive work and encourages
experimentation with crusher-X.

Although crusher-X is a very complex and sophisticated program, it is
very inexpensive shareware. But also without registration you can have
mutch fun while testing the program.

I hope you have fun creating crusher-sounds,
i=B4m more than happy for criticism and feedback,
Best wishes,

  1. Stelkens


P.S. If you want to be removed from that list, please give me a little note.
Thank=B4s for your patience!

Subject: Re: Additive synthesis control

Georg Hajdu is doing additive synthesis in MSP with data he's converting from
Lemur:

If you look at the implementation of coll (the source to which
is an example in the Max SDK) you'll see that it uses linear
search every time you look something up.

> Does it make a difference for "coll" whether to use index numbers or a
> goto/next pair in terms of performance?

It's a linked list, so random indexing is always going to take linear time
(proportional to the number of elements in the coll). "next" is much more
efficient.

What you should be using is SDIF, the Sound Description Interchange Format,
a new standard file (and network streaming) format that CNMAT and IRCAM are
pushing on the analysis/synthesis community. See
http://www.cnmat.berkeley.edu/SDIFfor details.

Lemur doesn't yet output SDIF files, but it would be no more difficult to
convert Lemur files to SDIF than to convert them to coll files. (I'll help
write this converter if necessary.)

I've made a collection of Max/MSP objects to read SDIF files, represent them


in "SDIF-buffer" objects analogous to "buffer~"s, and pull information out
into Max lists. I've been using it for additive synthesis of large data
files; no problem. In fact, the distribution I made includes additive
synthesis examples.

I just now made a link to the MSP SDIF stuff from the usual CNMAT Max page:
http://www.cnmat.berkeley.edu/MaxYou can also find it all under the SDIF
page.
