mrpeach client-server file sharing
by patco 17 Sep '08

17 Sep '08

Hello, I need to send an image file from a gem computer to another, mrpeach socket objects can open and send a file, but how do we retrieve the file? We get strings on the client and I've no clue how to convert this to a file on the hard drive, best.

pdmtl file.browser
by Derek Holzer 17 Sep '08

17 Sep '08

Just looking at the file.browser from the PdMTL collection. Very nice, cross platform, cool. The one feature I miss from [playlist] in it is the wrapping function of the file index. Is there any easy way to get the total number of files in a directory out so that the file selection number can be wrapped? d. -- derek holzer ::: http://www.umatic.nl ::: http://blog.myspace.com/macumbista ---Oblique Strategy # 88: "Imagine the music as a set of disconnected events"

pd installation on Mandriva Spring
by chi ball 16 Sep '08

16 Sep '08

Hi, I've downloaded "pd-0.41-0.src.tar.gz" and I've installed it succesfully on Mandriva Free 2008 Spring (using ./configure, make, make install). But when I load it from a root terminal, it go in loop with message: error while loading shared libraries: libtk8.5.so: cannot open shared object file: No such file or directory priority 98 scheduling enabled. priority 96 scheduling enabled. watchdog: signaling pd... watchdog: signaling pd... watchdog: signaling pd... watchdog: signaling pd... ecc.ecc. The latest Tcl/Tk libraries are installed. How i can solve the problem? Exist a "rpm" of pd-extended for Mandriva-Spring? Thanks, T. _________________________________________________________________ Cerchi un locale per la serata? Chiedilo a Live Maps! http://maps.live.it/

receive from multiple symbols in an external (using pd_bind)
by Jacob Lee 16 Sep '08

16 Sep '08

I'm trying to hack plugin~ to accept a "bind foo" message that causes it to listen for messages sent to "foo-gain", "foo-drive", etc., as determined by the list of parameters the plugin accepts. Right now, every time I want to try out a new plugin, I have to do a bunch of wiring to receive a message, scale it appropriately (since I keep all my adjustable parameters in the range 0-127), and convert it to something like "control drive $1". My goal is to eliminate most of those steps with some help from plugin~ itself, which should be able to enumerate all the inputs, get their range, and listen for messages appropriately. The problem I'm running into is that if I have made multiple pd_bind calls in the same object, to receive based on more than one symbol, I can't tell which symbol the incoming messages came from. For example, if I do: pd_bind(&x->x_obj.ob_pd, gensym("a")); pd_bind(&x->x_obj.ob_pd, gensym("b")); and create corresponding [s a] and [s b] objects, I will receive messages sent via those objects -- but there is no indication which came from which. The complicated workaround is to create a new object for each symbol I want to receive on. But before I pursue that (tedious and difficult) route, is there a more straightforward way to accomplish this? Thanks, -- Jacob Lee artdent(a)gmail.com

[import] verbosity
by Phil Stone 16 Sep '08

16 Sep '08

I'm using [import] on an abstraction (as discussed earlier); this abstraction does some automatic object instantiation (via [polypoly]) and each of the generated objects has an [import ...] in it. This leads to a barrage of console output, like: [import] loaded library: 'cyclone' libdir_loader: added 'cyclone' to the canvas-local objectclass path libdir_loader: added 'cyclone' to the canvas-local objectclass path [import] loaded library: 'cyclone' libdir_loader: added 'cyclone' to the canvas-local objectclass path libdir_loader: added 'cyclone' to the canvas-local objectclass path . . . (repeat for number of voices created by [polypoly]. A great enhancement for [import] would be a verbosity control! :-) Phil Stone

hid mouse repeats wheel and relative position events infinitely?
by Martin Schied 16 Sep '08

16 Sep '08

Hello out there... I'm using 'hid' from 0.40.3-extended in ubuntu hardy. After opening the mouse device everything seems to be fine at first (all number boxes in the example patch change on clicks and wheel-moves as expected), but when I'm trying to use mouse-wheel or relative position I was little surprised that those events are beeing repeated until I send a 0 or close Mesage to the hid object. Like this i can get single events out of it, but i don't think that's a good idea, closing and reopening the device all the time. I tried a new Logitech RX1000 and an older optical Logitech USB Mouse without differences. I'll try a PS/2 Mouse later... example-patch attached.

dinosaurs: fibonnaci and taking cues from analog processes
by Damian Stewart 15 Sep '08

15 Sep '08

hey list, back when i started using pd, some years ago, i can remember struggling to find anything made using it that sounded _good_. it seemed to be great for making 8bit sounds and tinny FM synthesis; but not so good for the big lushness one might expect a DSP synthesis thing to be capable of. so.. over the last year i've been developing a bunch of techniques for making things sound 'rich' in the way that analog gear can sound. the techniques are based on ideas of inexactness and shifting over time, recognizing that in an analog system concert A will never be exactly 440Hz, and it will shift over time as the conditions change, disrupting our brain's pattern-recognition systems and leading to a more rewarding sonic experience. the thing i'm most proud of right now is [d-fbdelay~], which is a stereo feedback delay with built in highpass and lowpass filters and a tape-flutter emulation effect. the tape-flutter is responsible for much of the richness of the synth sounds, i think. it works by smoothly changing the delay time of the delay channels slightly - by 1% or 2% - over time, to simulate an every so slightly worn out tape motor. it also effects the filter parameters. (for a nice demo grab the lowpass filter slider and whip it up and down quickly - it should make a click that disappears beautifully off into the ether.) the other nice thing is [d-modes] which outputs MIDI notes for incoming scale degrees based on a current tonal mode (eg ionian, dorian, phrygian, lydian..), and includes a small amount of random detuning to further break up the randomness. scale degrees are being triggered by a random function with a fibonnaci distribution so that the tonic and dominant are triggered more often. then there's the [d-biquadcalc-*] objects, which rebuild ggee's biquad filter objects in pure pd. these are a work in progress. and [d-reverb2~] just wraps [rev3~] from the help patches. anyway. attached you'll find dinosaurs.tgz, which contains _dinosaurs.pd and a bunch of support files extracted from my own dlib (which, yes, i still need to get around to releasing). it is pure-pd and will definitely work with any Pd >= 0.40.3, and perhaps earlier. it might throw some errors about mrpeach objects but don't worry about that, i'm not using them yet. at the moment the only real problem is that the biquad filter clicks sometimes when you change the sliders. i don't think there's a way around this, unfortunately. i might have to do a new external version of [biquad~] that internally ramps the values to avoid this. let me know if you like it. myself, i could listen to it for hours. it's very late, and i should be in bed, et cetera; but i think this might be the way to make the phantom music i hear sometimes in fans and ducts and air conditioning systems in empty offices and industrial spaces; the sounds of pieces of machinery slowly wearing themselves down to nothing, the sound of dead dinosaurs burning, ruining our winters. and what do you know, it's just the fibonacci sequence... d -- damian stewart | skype: damiansnz | damian(a)frey.co.nz frey | live art with machines | http://www.frey.co.nz

[feat. request] close window notifications
by y 15 Sep '08

15 Sep '08

Hello. I dunno if it's possible but it would be *really cool* to be able to turn the window-closing-notifications off (== no more "Close this window?" or "Really quit?"...). Or at least turn it off if the patch that is being closed is already saved ? Cheers, _y

mp3cast~ question
by Peter O'Doherty 14 Sep '08

14 Sep '08

Hi, Is anyone using this successfully? I'm using the example setup in the mp3cast~ help file and everything seems to be set up correctly here, confirmed by these messages: mp3cast~: connecting to port 8000 mp3cast~: logged in to localhost mp3cast~ : using lame version : 3.98 mp3cast~ : lame initialization done. (1) mp3cast~: initialising buffers mp3cast~: mp3 streamer version 0.5, written by Yves Degoyon LAME mp3 settings: output sample rate: 44100 Hz bitrate: 128 kbit/s mode: stereo quality: 4 mp3 chunk size: 2304 server type is IceCast 2 However, when I open the stream on VLC, the VLC counter runs but there is no sound. This seems to be a only small glitch but I can't see what the problem is. Does anyone have any ideas/ suggestions? Many thanks, Peter ---- Peter O'Doherty http://www.peterodoherty.net http://www.myspace.com/peterodoherty ----

netpd
by Josh Lawrence 14 Sep '08

14 Sep '08

Hello list, I just recently discovered netpd, which is frigging AWESOME for those of us newbies that can't program PD very well just yet. However, I have a problem - when I open up _chat.pd, it's looking for people on my own LAN. Can I jam with folks across the internet? Is there a main server or servers that I can connect to? And if so, can you point me to the RTFM on that? Thanks! -- Josh Lawrence http://www.hardbop200.com
