[PD] a little phenomenon ..
Hello Miller and the pd-list, i have just felt like this is a bit of a discovery, i will accept bricks thrown at me, but i doubt that is gonna happend. i am not very sure ..may be this is purely a personal discovery, but it doesn't feel like a personal one. this was really sudden and ..basically you can see the patch in the attachment. when you use it as an abstraction you have to stick a filter after it, otherwise something might blow. so this gives us a very interesting unit generator which i'm right in a middle (expect we are still terribly long way to the actual middle) of observing of what it can do :) i didn't mean that it can launch rockets, but the energy is all being transfered ..well, i'm not too sure, basicallt i'm trying to talk about that the tangent function goes up to infinity, and if we flat that down it's like an infinite energy that we are getting form it. oops, sorry i have actually put [/~ 0.5] and that's why it was blowing my headphones and seemed to have too much energy! hell.. anyway this seems to be quite a nice ugen, isn't it? ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
[PD] pdcon09 and iscl2009
hi, I put the rest of my pics from sao paulo and bahia online. thanks to all the organizers, alex, figo, glerm, paloma, karla and all people who helped support the two events. I think pd community (...) gains a lot of energy from the events, in brazil, south america and everywhere else. http://www.flickr.com/photos/23071...@n00/sets/72157621754454542/ http://www.flickr.com/photos/23071...@n00/sets/72157621921524442/ marius. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
[PD] Help Docs: element vs. item
[list one two three( How should the help patches refer to "one" above: as the first element or the first item in the list? Currently the reference docs use both, and I'd like to pick one and stick to it. -Jonathan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
[PD] [Openlab] pubcode2 - livecoded music + vjs, London, Wednesday 5th August
++ PUBCODE2 ++ Part two in the first series of livecoded music events in London. http://toplap.org/uk/ Live coding is a new direction in electronic music and video, and is starting to get somewhere interesting. Live coders expose and rewire the innards of software while it generates improvised music and/or visuals. All code manipulation is projected for your pleasure. When: 7pm - 11pm, Wednesday 5th August 2009 http://toplap.org/uk/event/pubcode2/ Featuring: chr15m (making machines that make machines that make music) MCLD (beatboxing + livecoding, is it possible?) Yee-King + Click Nilson (algorithmic choreography) openSlub (crowdsourced livecoding) Place: The Roebuck 50 Great Dover Street London SE1 4YG Map: http://is.gd/CL5G Door tax: Free Tube: Borough (5 mins walk) London Bridge (9 mins walk) More info: http://toplap.org/uk/ ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] pdp question
ola, the pdp_glx object accepts a message : [posdim x y width height (, so a message [posdim 1025 0 1024 768( should work for a resolution of 1024x768, it should be full screen on your extended desktop. in linux, gnome doesn't let you position a window on 0, so you have to use a window manager like fluxbox. i don't know the situation on macosx. saludos, sevy budi prakosa wrote: can i use fullscreen+borderless window using pdp like gem? i use macosx thanks! ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
