Hi Rich,
It's at version 1.0.1 right now so go to: http://ico.bukvic.net/Max/munger1~_1.0.1.tar.gz
Once you get it compiled you may be interested in the GUI I posted to the list several days ago. The subject was "munger1~ GOP [was Re: munger1~ binary for ppc]"
Good luck, Kevin

SOURCE INSTALL
If you simply intend to use prebuilt binaries, please skip to the INSTALL section. Otherwise take a big breath and read on...
- You need stk library which can be downloaded from:
http://ccrma.stanford.edu/software/stk/
- You need to also install latest flext library (this is a library that
allows for creation of externals for both Max/MSP and PD using the same source). Version 0.4.x can obtained from the following link:
Latest CVS version (0.5.1) is found in the Pure-Data CVS (this one is recommended):
http://sourceforge.net/cvs/?group_id=55736
- If you are using latest CVS version (0.5.1) Before compiling the source
you will need to add the following to the top of the flext/source/flstk.h file right below the #define __FLSTK_H:
#ifdef PI #undef PI #endif
This step will probably become quickly obsolete once Thomas updates CVS. Until then, this is needed to be able to compile flext against stk.
- To compile flext, read flext instructions (it boils down to running
build.sh with appropriate parameters and then editing two simple config files, i.e. "build pd gcc build" or "build max gcc" or "build max msvc" etc.)
Your will need to edit
buildsys/config-<platform-compiler-pdormax>.txt to
adjust paths to various folders.
Then you will need to edit config.txt file. You do not need to include SndObj for this external but you do need stk option to be properly set. On Windows+MSVC, STK flag at the time of this release does not work, so you will have to use included testmunger1 MSVC project file and adjust path settings to compile munger1~.
- Once stk and flext are compiled, go into munger1~ folder and type:
<path to flext folder>/build.sh <platform> <compiler>
<build/clean/install>
NB: on Mac <build/clean/install> is not needed. On Windows, please use
MSVC
and open the testmunger1 project file in the root of the folder.
- Once compiled, your binary will be created in a <maxorpd-platform>
subfolder (i.e. pd-linux, or max-darwin), followed by another subfolder which reflects whether a threaded or singlethread flext was used. Inside
you
will find your external.
INSTALL
You can either use the prebuilt externals (found in the bin/ folder) or
ones
built using the "SOURCE INSTALL" instructions above. Binaries are provided for Intel-based Macs, Win32, and Intel-based Linux OS. The included
prebuilt
binaries DO NOT REQUIRE you to install flext or stk as these are
statically
linked.
- Copy the external in your externals folder (i.e. /usr/lib/pd/extra or
C:\Program Files\Cycling '74\MaxMSP 4.6\Cycling '74\externals, or "Applications/MaxMSP 4.6/Cycling '74/externals)
- Copy appropriate help file (found in the help/ folder) into the help
folder (i.e. /usr/lib/pd/doc/5.reference or C:\Program Files\Cycling '74\MaxMSP 4.6\max-help, or "Applications/MaxMSP 4.6/max-help)
NB: Pd help file has a ".pd" extension, while Max/MSP help file has a ".help" extension.
- Start your app (PD or Max) and create object called munger1~.
Right-click
(ctrl-click on Macs) and select "help" and this should open the help file with additional documentation.

FAQ
The following is Ico's FAQ, so it may or may not reflect other project participants' opinions, including original author(s) of munger~, flext,
etc.
Q: Why porting to flext? A: Flext library (by Thomas Grill) is a layer which allows creation of externals for both Max/MSP and PD without any alterations to the code (obviously once it is adapted to use flext). While there have been a
number
of Max/MSP <-> PD external ports in the past, many of them have become outdated because such attempts required either maintaining one code full
of
ugly #ifdefs, or worse--maintaining two sources. Either way, what usually turned out to be the case is that original authors did not have the time, interest, or simply the software/hardware to deal with the newly generated overhead and/or test the code, while volunteers who made the original porting efforts eventually moved on to other projects. The result was/is outdated and/or broken externals. Flext circumvents this problem by
allowing
one clean code to compile on both platforms while also supplying in many cases cleaner (more legible) API and (as a whipped cream on top) object-oriented environment (C++).
Q: Why bother with PD <-> Max/MSP cross-platform compatibility... ...when I use only
<insert-your-favorite-application-here>?
...<insert-your-favorite-application-here> is better? A: Choice is what makes us human (this is also what makes Arts so vibrant and exciting). And while everyone's welcome to express their own preferences, we also have to realize that in this case these same preferences are also the main cause of a virtual divide which manifests itself at everyone's detriment. Wouldn't it be nicer if we could share externals transparently, or even better, open PD patches in Max and vice-versa? This would help in both the cross-pollination of ideas as well as creative efforts. This project has also taught me that creating flext-ready externals is as easy if not easier (due to the aforesaid API's legibility) than native objects (whether that be PD or Max/MSP). Finally,
if
all else fails, such externals are bound to reach wider audience, and are much easier to maintain if cross-platform compatibility is to be pursued.
Q: If flext is so cool, why don't we see more porting efforts? A: Good question. The fact is that flext is much more widely known among
PD
users than it is among the Max/MSP community, so this seemingly one-way
road
may have contributed to the current situation. One could only hope that projects like this may help reverse this unfortunate trend.
Q: So, is all really that peachy in the flext-land? A: Well, our lives teach us that nothing is truly free in this world.
Flext
is no exception. Its "fees," however are not tied to our checkbooks.
Rather,
they manifest themselves in a slightly greater CPU overhead in signal flow due to message translation. Thus, one could consider flext a
"middle-person"
between the <app-of-your-choice> and the external. This, however, in
today's
world is so negligible that during the testing phase I was unable to
measure
any noticeable CPU-overhead difference.
Another consideration is that flext might not be complete (see KNOWN
ISSUES
for an example). That being said, in its current state it did the trick
for
a relatively complex external such as munger~ or even FFTEASE collection which had been ported several years ago. All this leads me to believe that it is more than ready for the day-to-day use.
KNOWN ISSUES
munger1~ has been tested extensively on Linux+PD, OSX+Max/MSP and Win32+Max/MSP setups, suggesting that it should work on other setups as well. Your mileage may vary, though.
Currently there is only one known issue in the wild which requires changes to flext in order to be fixed. Namely, if you use munger1~ object in conjunction with an external buffer in PD (known as an array) and if you dubiously decide to delete that particular buffer in the middle of your performance while munger1~ is still associated with it, this will [unsurprisingly] crash PD. Max/MSP currently has a check implemented
against
that via flext layer so Max/MSP will simply stop outputting anything until buffer is reset. The flext author is aware of this and PD fix should
appear
in the flext CVS hopefully soon. That being said, the lingering question
is
why would you want to do this in the first place...
FYI, even though munger1~ allows up to 500 simultaneous grains per sample and has been compiled with all available optimizations (SSE, Altivec is supposedly available via flext but has not been tested), on MBP (Core Duo 1.83GHz) I was unable to get more than 160 simultaneous grains per sample (or ~32,000 grains/second) without dropouts, even though CPUs were not getting maxed out, so something else might be the cause of this limitation (flext?). Win32 machine (3-year old AMD64 3000+) fared marginally better
at
around 165 simultaneous grains per sample (or ~33,000 grains/second)
before
its CPU was maxed out. Linux on the same AMD64 3000+ hardware fared the best. It topped off at 47,999 grains per second at 48KHz sampling rate
which
for some reason the sampling rate appears to be the upper limit ( i.e. if
you
run PD or Max/MSP at lower sampling rates, your upper limit will be restricted to the sampling rate), even though the code allows for multiple initiations of grains per cycle. This, however, is also the way original munger~ works.
An interesting bit is that while on Linux/PD combo 48K grains are already reached when we get 64 simultaneous grains, on Win32/Mac even 160 simultaneous grains yield only ~32-33K grains. Could this be a flext bug?
