external-writing question about inlets
by J. Scott Hildebrand 08 Aug '03

08 Aug '03

right now i'm converting my convolution external to take as many inputs as the user would like. i'd like to call it like this: multiconvo~ <number of sources> is there a way to do this? here is the current code i gotta play with: static void convaudio2_tilde_dsp(t_convaudio2_tilde *x, t_signal **sp) { dsp_add(convaudio2_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 convaudio2_first(t_convaudio2_tilde *x, t_floatarg f) { x->firstfloat = f; } static void convaudio2_bound(t_convaudio2_tilde *x, t_floatarg f) { x->secondfloat = f; } static void *convaudio2_tilde_new(t_floatarg f) { t_convaudio2_tilde *x = (t_convaudio2_tilde *)pd_new(convaudio2_tilde_class); x->f_convaudio2 = f; //additional signal and float inlets inlet_new(&x->x_obj, &x->x_obj.ob_pd, &s_signal, &s_signal); 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")); //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 convaudio2_tilde_setup(void) { convaudio2_tilde_class = class_new(gensym("convaudio2~"), (t_newmethod)convaudio2_tilde_new, 0, sizeof(t_convaudio2_tilde), CLASS_DEFAULT, A_DEFFLOAT, 0); class_addmethod(convaudio2_tilde_class, (t_method)convaudio2_tilde_dsp, gensym("dsp"), 0); class_addmethod(convaudio2_tilde_class, (t_method)convaudio2_first, gensym("first"), A_FLOAT, 0); class_addmethod(convaudio2_tilde_class, (t_method)convaudio2_bound, gensym("bound"), A_FLOAT, 0); CLASS_MAINSIGNALIN(convaudio2_tilde_class, t_convaudio2_tilde, f); -------------------------------------------------------------------- "640K ought to be enough for anybody." -- Bill Gates, 1981 --------------------------------------------------------------------

convert in vst or exe
by Roman Haefeli 07 Aug '03

07 Aug '03

hi i'm sure i'm not the first with this question. is it possible to create vst-plugins or .exe-files with your own patches? it would be nice if have only one file wich i can give to my friends who don't know pd well but like using my patches. thanx

hi list, some questions: where's the information on cvs checkout? are there pbprojects for pd and gem, or other favored compilers? does pd and/or gem run better on linux then osx ( i have only macs, but want a dedicated comp for video). are there any other packages for video running on g4 (osx or linux). thanks, adrian

audio glitches using arrays?
by evan raskob [PD] 06 Aug '03

06 Aug '03

hello pd gurus, one big issue i'm having is that you can't load audio files into arrays without having the whole system pause for the new file to load. In fact, any time I change an array, the whole system pauses. is that because of lag, or because the arrays aren't multi-threaded? the writesf~ object seamlessly writes sound files in the background - why can't i load/record them into arrays just as seamlessly? (I use OSX and pd-0.36) thanks, -evan raskob

dv gem or hi-res video
by unorosso＠mac.com 06 Aug '03

06 Aug '03

Have you any experience to share on using gem to _play_ high res video? I am working with a friend to a simple video sequencer, but the main problem is using the right compression codec to me. I don't mind a brute force solution, but so far some codecs crash gem with full pal. If someone has also a pointer I'll aprreciate very much :) fredd ----------SUb-------- | www.submultimedia.tv |

there should be a file called 0.INTRO.txt, located in pd/doc/5.reference. which version of pd are you using? marius. ----- Original Message ----- From: <Loislaplace(a)aol.com> To: <marius.schebella(a)chello.at> Sent: Wednesday, August 06, 2003 12:24 PM Subject: Re: [PD] glossary Dans un e-mail datÃ© du 06/08/2003 11:57:46 Europe de l'Ouest (heure d'Ã©t, marius.schebella(a)chello.at a Ã©crit : > otherwise, when I do right click on main frame, i obtaine the popup window > "propertie, help" > loÃ¯s > > yes, and then select help. isn't that what youre looking for? > marius. sorry marius, but when I click on "help" nothing happen maybee a good file is not in the good folder in my configuration. what do you think about this ?

In fact I am looking for a glossary of the codes that can be use to create object as for ex : osc~ 440 to create a sinwave. otherwise, when I do right click on main frame, i obtaine the popup window "propertie, help" loïs

hello, I got pure data two days ago, it seems to be a really fantastic software. Does anyone can tell me where it is possible to find a glossary of all the term that can be use to make some patches ? thx, loïs

RE: [PD] GUI idea and some other thoughts

> also, in my opinion Pd is weak as a typical artist's tool to make music. In my opinion as, what I guess would be a typical artist, it is the most powerful tool I have ever used. I think people just need to change their 'typical artist' mindset. If you go into it thinking you are going to get LIVE or Cubase you will be very disappointed. If you go in thinking you get a blank canvas to literally do whatever you want, you will be freaked out and happy, and maybe a bit overwhelmed at first. > i know it's a lot of work but > might be easier for somebody who's written such a program that's > open-source... to learn a bit about Pd's framework and port/modify their > existing stuff. The main problem is basically your first sentence. It's a lot of work. I have been doing more experiments lately with the data structures that sort of mimic some of the functionality I want to bring over from other programs. Using Krzysztof Czaja's Toys you can even start to build GUI stuff (if that is what you want to do, I'm leaning towards using as much of the base PD stuff as possible). Any way you approach the problem it's a big long development time. For what in the end? A copy of logic? Premiere? I would rather experiment and find a new working style. And if you really wanted to have something that was Cubase or Nuendo, why not just buy that? It is out there and it will most likely have a lot less bugs than anything I would write in PD that tried to emulate it. The main reason I'm doing this stuff is to really learn about everything PD has to offer, I give myself a problem like, if I want and arrange window like Logic in PD what would I have to do to get it, and I gradually build something that isn't quite the arrange window, but is pretty interesting and does some cool stuff, plus I learn a ton more about PD in the process. m.

My point exactly. I currently am using it more as a learning tool. Whenever I start looking at something new I need to be able to have a focus in order to really learn the ins and outs of the program/language. For PD that focus has been, lets start with some things whose logic I completely understand, and which will let me explore PD capabilities, so my first 2 big patches were a step sequencer (control signals) and a 3op polyphonic FM synth (audio signals), once these 2 are done the next problem I am setting for myself is, what project can I do to explore Data structures, and I think for me that is going to be some sort of sample/sequence arranger, akin to the arrange window in cubase or logic. I'm sure my end product will be more than what I am expecting, and completely different from the commercially available stuff, but my goal really is to know Data structures, which I am sure I will accomplish. m.
