GEM: pix_multiimage multiple instances
by Mark Havryliv 14 Aug '03

14 Aug '03

Hi everyone, I'm trying to have more than one pix_multiimage under the same GemHead but I can't get it to work. I have used separator properly and perform both pix_multiimage's after their respective separators, but only one will let me change images. The whole process works fine if I replace the two separators with two GemHeads. Is this a feature of pix_multiimage or a bug or am I missing something? Cheers, Mark Havryliv _________________________________________________________________ Hot chart ringtones and polyphonics. Go to http://ninemsn.com.au/mobilemania/default.asp

GCC for MacOSX/Flashserver
by Willem Paling 14 Aug '03

14 Aug '03

OK, So I'm trying to get my university (University of Technology Sydney) to let me install PD and the Flashserver internal in the computing lab so I can use it for a project I'm doing this semester. They've kindly given the OK and we installed PD today. So Olaf says here http://www.akustische-kunst.org/puredata/flash/flash.html that the sources only compile with PD 0.37, we have PD 0.36 installed. So I downloaded the file flashserver-0.2g.zip and found there was no binary for OSX, so I couldn't install it. So the first thing I want to know is, given that v0.2h will not COMPILE with PD 0.36, is there anything wrong with a binary version? If so, can anyone either point me to somewhere that I can acquire GCC for macosx so that I can compile v0.2g myself (I've had a real hard time finding it, everywhere seems to imply that you need developer tools installed regardless). Or better still, if there if anyone can send me a binary for macosx of v0.2g, that'd be swell. I did briefly test the v0.2h binary with PD 0.36 on OSX, and found that it worked ok. But I wanted to be sure, as I'd rather get it all setup properly to start with rather than having to annoy the lab admin by making him come and fix it up for me all the time. Thanks Willem

multi source convolution help
by J. Scott Hildebrand 13 Aug '03

13 Aug '03

the way i want it to work is have the first inlet be azimuth, the second inlet be elevation, and the third inlet be which signal inlet to use. at creation time the user specifies how many inputs they want, and i think i have that working now... finally. the first three inlets will be floats, and the other ones will be signals based on how many the user wants to use. additionally, i'd like to store the pointers to each signal inlet in an array somehow, so that i can access a specific one based on the select input (i'm not sure how to do this). any help is appreciated! here's the code i have so far that only makes a specified amount of signal inlets, but i don't know how to get rid of the first DSP inlet and make that a float. static void multi_source_convolution_tilde_dsp(t_multi_source_convolution_tilde *x, t_signal **sp) { //dsp_add(multi_source_convolution_tilde_perform, 6, x, sp[0]->s_vec, sp[1]->s_vec, sp[2]->s_vec, sp[3]->s_vec, sp[0]->s_n); } static void multi_source_convolution_first(t_multi_source_convolution_tilde *x, t_floatarg f) { x->firstfloat = f; } static void multi_source_convolution_bound(t_multi_source_convolution_tilde *x, t_floatarg f) { x->secondfloat = f; } static void *multi_source_convolution_tilde_new(t_floatarg f) { int b; //int a = (int)atom_getintarg(0, argc, argv); //int i = (int)atom_getintarg(1, argc, argv); t_multi_source_convolution_tilde *x = (t_multi_source_convolution_tilde *)pd_new(multi_source_convolution_tilde_class); x->f_multi_source_convolution = f; x->i_count=f; //additional signal and float inlets //inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("first")); //inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("bound")); for(b = 0; b < x->i_count; b++) { inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); } //i = argv[2].a_w.w_float; //i = argv[2].a_w->w_float; /* i = atom_getintarg(2, argc, argv); if(argc == 2) { for(a = 0; a < i; a++) { inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); } } */ //two signal outlets for stereo outlet_new(&x->x_obj, &s_signal); outlet_new(&x->x_obj, &s_signal); return (void *)x; } //setup declares new classes and their properties void multi_source_convolution_tilde_setup(void) { multi_source_convolution_tilde_class = class_new(gensym("multi_source_convolution~"), (t_newmethod)multi_source_convolution_tilde_new, 0, sizeof(t_multi_source_convolution_tilde), CLASS_DEFAULT, A_DEFFLOAT, 0); class_addmethod(multi_source_convolution_tilde_class, (t_method)multi_source_convolution_tilde_dsp, gensym("dsp"), 0); class_addmethod(multi_source_convolution_tilde_class, (t_method)multi_source_convolution_first, gensym("first"), A_FLOAT, 0); class_addmethod(multi_source_convolution_tilde_class, (t_method)multi_source_convolution_bound, gensym("bound"), A_FLOAT, 0); CLASS_MAINSIGNALIN(multi_source_convolution_tilde_class, t_multi_source_convolution_tilde, f); } -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

CPU: I think [switch~] is going to be my friend, I'm just going to have to set up some sort of mechanism to make sure it gets turned off when the amplitude envelope hits 0. Voice loudness: I think just dividing the 8 outputs before they get to the main out is the first thing I will try. T3: Frank's Drum tutorial will hopefully someday help us :) but until then I'm going to try and systematically figure out what the list of numbers is doing. m. > -----Original Message----- > From: Josh Steiner [mailto:josh@vitriolix.com] > notes, looks like you ran into all the same hangups i did, namely: > > "The envelopes are [line] and [line~] driven.

Web interface for PD patch
by lists＠martinmalm.com 13 Aug '03

13 Aug '03

Hi everyone ! I need to control a simple PD patch via a webinterface. Since I know a little bit of Java I would like to use some kind of applet, but I don't know If this is possible ? What other methods / frameworks would work ? For this installation I only need oneway WEB -> PD, but it would be fun to know how to implement two way comunication also. I would be really happy if someone who has done stuff like this before could point me in the right direction or maybe provide a simple example. All the best / Martin Malm

Hello all, I'm looking for something that will take a sequence of atoms (floats) and package them into a list, regardless of how many there are... Any ideas/externals? Thanks B

here's some code i'm messing with. i want to get the second argument from an external declaration, and then use that number to create a certain amount of inlets. here' the code, and there's some shit commented out that i was just playing around with but couldn't get to work. static void *multi_source_convolution_tilde_new(t_floatarg f, int argc, t_atom *argv) { int a = (int)atom_getintarg(0, argc, argv); int i = (int)atom_getintarg(1, argc, argv); t_multi_source_convolution_tilde *x = (t_multi_source_convolution_tilde *)pd_new(multi_source_convolution_tilde_class); x->f_multi_source_convolution = f; //additional signal and float inlets inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("first")); inlet_new(&x->x_obj, &x->x_obj.ob_pd, gensym("float"), gensym("bound")); //i = argv[2].a_w.w_float; //i = argv[2].a_w->w_float; /* i = atom_getintarg(2, argc, argv); if(argc == 2) { for(a = 0; a < i; a++) { inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); } } */ post("OUTSIDE"); if(i == 0) { post("zero"); } if(i == 1) { post("one"); } if(i == 2) { post("two"); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); } else if( (argc == 1) || (argc > 2) ) { inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); } //two signal outlets for stereo outlet_new(&x->x_obj, &s_signal); outlet_new(&x->x_obj, &s_signal); return (void *)x; } -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

After all it is a >tool for developers and not a distribution channel. > you could use some tags to identify stable releases or at least useable ones...hum, anyway i find it strange that the latest tarball of Gem is so old given the amount of development there have been here. well, my 0.2 euros.. hasta la vista, sevy
