Re: [PD] sending notes OSC

hi adrian, I read: > but I manage to send text characters, numbers or whatever to other IP > addresses using 'send' in a message box and joining it to sendOSC but how do > you send sound, OSC is a control protocol not meant for streaming sound data in a reasonable amount of time (though you could of course use: [tabread] | [pd yourOSCsender] . . (imagine powerpoint internet cloud here) . [pd yourOSCreceiver] | [tabwrite] ) > I've a little osc~ set up where I can hear my own sound on > my pc but I dont know what the object or message is to send it to another IP well in pd you could always look into the pd internal messages docs and clone your patch at the other end but I don't think that's what you want. again: OSC != streaming it was designed as a more versatile, contemporary, typed, urlstyle , physical layer independent midi replacement see: http://www.cnmat.berkeley.edu/OpenSoundControl/ HTH x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

Re: [PD] vasp, segfault
by CK 12 Nov '03

hi thomas, I read: > does this mean that you can't create any vasp object? ( i assume the vasp > library does load normally) no, I can load the lib and most of the objects (I probably missed some abstraction path) generate fine, I can also use a lot of the help stuff in vasp/pd but all the stuff in vasp/pd_ex it tested causes a segfault [...] > I'll see what could go wrong but i'm not sure if i have a solution shortly. I'll try to recompile today afternoon with -g (pd && flext && vasp) and see if gdb reveals sth. useful (if I find the time). regards, x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

vasp, segfault
by CK 12 Nov '03

12 Nov '03

hi thomas and the rest, I've just revisited vasp but I run into lots of trouble, flext and vasp cvs update today morning didn't help much whatever example I try I get several > convolve 1 0 27 0 (vasp.frames?->text) connection failed > convolve 5 0 20 0 (text->vasp.radio) connection failed > convolve 22 0 26 0 (text->text) connection failed > convolve 24 0 22 0 (canvas->text) connection failed > convolve 25 0 22 1 (canvas->text) connection failed . . and similar messages, whatever I try out immediately segfaults that is debian-ppc unstable on a g4 any hints ? x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

Some VASP questions
by Larry Troxler 12 Nov '03

12 Nov '03

Hi, I have some questions about, guess what? - VASP! I'm trying to put together a simple FFT scope. Here are some things I'm not sure about. First, How should I use the "detach" message, assuming that i want my scope to run always in a seperate thread (so that there's no issues in switching it back and forth)? Should I send the "detach" message first, before starting processing? Next, "vasp.window" apparently doesn't handle the "to" message, so how do I deal with that? I thought the approach would be to chain all the objects to gether and send the first one a "to" message to set the source and destination arrays, and everything would be well. Now about the fft stuff - I am not sure what vasp.rfft does actually. It seems like that's what I want to use, becuase I'm dealing with an audio signal. But what does it output, and how does that map into a PD array? Is it generating the full complex FFT, including the redundant conjugates? And are only the real compenents of this making it to the arrary, or is there a mag operation done before writing to the array? And if so, is there a way that I can write only the magnitudes of the first half of the output to my array? IOW basically, for an FFT of a real signal, I only want the first half, so my output array should be half the length of the input array. And for simple energy plot, each point in the array should be the magnitude vector of the corresponding point in the FFT. Is this somehow what is already done, or do I need to do something else to accomplish this? Thanks in advance! Larry

Re: [PD] Pd minimum requirements
by Emmanuel Rio 12 Nov '03

Hi, I managed to run PD (version 0.36-0) on a Toshiba Satellite 100CS, which is a laptop PC. Main specs : - Pentium I (75 Mhz) - 810 MB Hard Disk - 8 MB RAM - Windows 95 Since it doesn't have any multimedia card, I could only test control stuff (actually, a metro and a bang). With a PCMCIA ethernet card I have, I could also test a netsend/netreceive connection with my current laptop (which has audio/midi capabilies). It works. I see two configurations for which it could be usefull : - for people who want to learn basics of control/programming approach in PD. - for a remote/shared control (via the network) of a "normal" multimedia PD.

Pd minimum requirements
by huolong＠arcor.de 11 Nov '03

11 Nov '03

hi list, i first thought on making the tutorial/manual only for windows, but as the chapter-C will cover the usage of Pd (will be huge) and that is allmost 100% compatible with any OS, so i thought i make the install and launch chapter also for linux and osx. for starters, i could use some help on defining the "minimum requirements" for Pd. please correct these points where you can: Microsoft Windows - Windows 98 (i don't think we need to mention win95) - 300 Mhz (if someone can test this, let me know if it's too slow) - 64 mb ram (should be enough) - 20 mb free on harddisk (maybe we could spare this point) - TCP/IP Protocol - Audio card (optional: for audio input/output) - MIDI card/device (optional: for MIDI input/output) - OpenGl compatible graphic card (optional: for GEM) - Video card/device (optional: for GEM, video input/output) well, it's not quite logical to mention that multimedia devices are "optional" for Pd, but you can use Pd for "normal" programming too... Macintosh OSX - osx version ? - ? mhz - ? mb ram - ? mb free on harddisk - TCP/IP Protocol - ? GNU/Linux - hardware same as windows ? - depencies ? - gcc version ? - kernel issues ? - ? IRIX (do we need this?) - ? question: Pd does audio signal processing even if you don't have an audio card ? (just input and output are not available ?) thanx -andre ps. as usual, you can mail me direct at huolong(a)arcor.de

More PD install on linux
by Wade McDaniel 11 Nov '03

11 Nov '03

Thank you for your help! I have another problem. It turns out that I may have set up the alsa stuff correctly (xmms plays...), but the compile of pd was hanging on portaudio. I installed portaudio, but now it hangs on pd_pablio.h. Portaudio's site says this is some subset (a python extension of portaudio) of portaudio, but i cant see where to install it from. Any tips? Thanks again for all your help! Viva open source! -wade
