ZeroConf for Max/MSP

Are you still using the old osc-bonjour? there's now the more flexible zeroconf.browse, zeroconf.resolve and zeroconf.register externals that let's you browse, resolve and register any kind of zeroconf services.

http://sourceforge.net/projects/osctools/files/

They are much more integrated with Max5 than osc-bonjour was, using attributes... etc

Field (not Fluid)

Marc Downie finally released its Digital Art framework called Field written in Jython and released under the GPL3 license.

Closed

I'm no longer working at Ircam. So I will no longer update this page in the future.

However I'll keep this page online for backup and I can still be contacted from there or from my independent smartelectronix webpage.

I've disabled comments until there's a better anti-stam for sphplog.

Oscbonjour update

Thanks to Charles Bascou from GMEM there's an update to the oscbonjour maxmsp externals for UniversalBinary.

see the old article for the download location

MaxMSP externals with ObjectiveC

yes, it's possible because ObjectiveC is a strict superset of C. You just need to use a *.m extension so that Xcode compiles it as ObjectiveC and not just C.

I already used C++ to write maxmsp externals so I knew it should be possible with another C based language. But I needed a proof of concept. here it is:



#include "ext.h"

#import 



@interface Fraction : NSObject

{

	int num;

	int den;

}

- (void) setNumerator: (int) d;

- (void) setDenominator: (int) d;

- (int) numerator;

- (int) denominator;

- (void) print;

@end



@implementation Fraction

- (void) setNumerator: (int) d

{

	num = d;

}

- (void) setDenominator: (int) d

{

	den = d;

}

- (int) numerator

{

	return num;

}

- (int) denominator

{

	return den;

}

- (void) print

{

	post("%i/%i",num,den);

}

@end



typedef struct

{

	t_object o;

	Fraction *frac; // to show how we can store an ObjectiveC instance inside a C struct.

} objc_t;



static t_messlist *objc_class = NULL;



static void *objc_new(Symbol *s, short ac, Atom *at)

{

	objc_t *o = (objc_t *)newobject(objc_class);

	Fraction *frac = [[Fraction alloc] init];

	[frac setNumerator: 1];

	[frac setDenominator: 4];

	[frac print];

	o->frac = frac;  		

	return o;

}

static void objc_free(objc_t *o)

{

	Fraction *frac = o->frac;

	if(frac)

	{

		[frac release];

	}

}

int main(void)

{

	setup(&objc_class, 

		  (method)objc_new, 

		  (method)objc_free, 

		  (short)sizeof(objc_t), 0L, 

		  A_GIMME, 0);

}

oscbonjour for maxmsp draft

beware this is just a draft

here is a max/msp external for OSX (UniversalBinary) and windows doing Bonjour/ZeroConf service discovery and announcement:

basically there are only 3 messages:
browse: browse for available services of type _osc._udp
resolve name: get hostname and port number from service name
register name port: register and a service of type _osc._udp with specificied name and UDP port number

here is the download link:
oscbonjour.zip

and the old one
oscbonjour_ppc_win.zip

for the windows version you'll need to install Bonjour for windows:
http://www.apple.com/fr/macosx/features/bonjour/

SourceCode

the sourcecode is available on sourceforge under a BSD license, you'll need 2 modules: oscbonjour and zeroconf, here are the commands you need to run:

svn co https://svn.sourceforge.net/svnroot/osctools/trunk/oscbonjour oscbonjour

svn co https://svn.sourceforge.net/svnroot/osctools/trunk/zeroconf zeroconf

Update

osc-bonjour for Max/MSP is no longer maintained, please use the more general zeroconf.browse, zeroconf.resolve and zeroconf.register externals instead.
They are much simpler and powerful and let you work with any kind of zeronf services, not just _osc._udp.

NIME06 day four

Open Sound Control meeting @ NIME06

We had a very interresting meeting with about 20 OSC developpers on thurday June 8th 2006 about the future of OSC standardization.

the meeting was lead by Matt Wright(CNMAT) with participation from David Wessel(CNMAT), Ali Momeni(CNMAT?), Emmanuel Flety(IRCAM), Seb Beaulieu (Plogue), me(IRCAM) the JazzMutant's team and many others whose names I don't remember.

Matt has put online an overview of the hot topics of the meeting:
http://www.opensoundcontrol.org/group_book/developers/nime06meeting

the highlights are on the usage of ZeroConf/Bonjour/Rendez-Vous for service discovery and registration,
OSC namespace discovery

NIME06 day two

NIME06 day one

the NIME06 conference that happens at IRCAM this year has officially started this morning.

Choreographic computations workshop II

We had very exciting and animated discussions during this workshop.

here are some picture I've taken before the battery of my camera went empty.

Scott Delahunta and Frederic Bevilacqua introducing the workshop.

Antonio Camurri

Marc Downie talking about his work with Trisha Brown using his own application framework called fluid

He told that Fluid (Java + Python) should be released (escaped?) in october under a "militant" GPL license.
