I once had the same problem. Just take one or more screenshots of the
printout areas and print them in Simple Text or Photoshop.

The "jimmies" are available on the new CD-ROM of the IRCAM Forum User
Group. However, this is only available for members of that group. I am
wondering if user who did not buy MSP from IRCAM would also have access to
the "jimmies"... I'd appreciate if they could be downloaded from the IRCAM
ftp server.

Here is the list of the available "jimmies" which I extracted from the
manual, sorted by types:

Subject: unlist

unlist is indeed PPC ready, and has been since the release of 3.5. It is
part of the Lobjects (OK it doesn't start with L) and can be found on the
3.5 CD. Some of the others on the CD are out of date- you can find new
versions at http://arts.ucsc.edu/ems/music/research/Lobjects.readme.html
and some new items, like a sensible counter.

Subject: hard disk recording in msp

Is there a way, a la Super Collider, to record the output of an MSP patch
straight to hard disk or is it  a case of using record~ and a very large
buffer ?

Thanks,

Good questions.

I'm trying to build a phonetic recognition patch without having to write my
own object (cause I'm a really bad C programmer).  If I do an fft on a wave
which works in real time I need fast objects to analyze the wave and tell
me where the forments are (the 3 or 4 loudest frequencies in the signal).
Max and min could work over a specified period of time on a buffer~ to tell
me at what frequency the maximum signal is.  Its more complicated than that
but thats the general idea.

'&&~' and '||~' objects would allow me to make multiple comparisons on
different parts of the wave. For instance I would like to compare the
current signal with another signal (easy enough with the >~ object), then I
need to find out whether that signal is also greater than my stored highest
position; if it is store it, if not throw it away.  Then  when I get
through analyzing all 512 samples I can have my own maximum~ object.

My biggest problem with this is I don't know how to store just one value in
a buffer and then use it in real time dsp.  I've tried to do all this using
the sah~ as well as delta~ and I haven't got it working quite yet.  In fact
this easy object sounds so complicated to do using just the >~ and <~ that
I've pulled out my C books.

I've only been using MSP for a month now, and as when I first learned Max,
I keep asking stupid questions.  Half of my problems I figure out before I
get a response from the list.

Thanks Richard Dudas for your comments about about the pages I missed in
the MSP manual about 512 vs. 513 sample lengths and buffers.

Any other comments would be greatly appreciated.
