routing PD gui commands back into PD via netreceive
by B. Bogart 06 Jan '06

06 Jan '06

Hey all, I had an idea for a performance that uses the communication channel between the PD-gui and PD as the raw material of the performance. So this question has two parts: #1. How can I start PD so that the PD GUI commands get sent to the regular PD port, as well as to a second port using a netreceive? I guess something like tee for sockets? #2. Any ideas on interpreting this data, it should all be ; delimited, so netreceive should see it fine, and there should be no illegal characters in it. How could I intrepret it rawly though? perhaps using any2ascii to convert each character into an ASCII value? Thanks all! This would be on OSX and/or linux. ..b.

Hi llist, was this synthÅ½s collection posted somewere? It is cause im looking for a good pd based synth. IÅ½d been looking at the docs inserts in the HansÅ½ rc6(congratulations) and in the docs of Pd++(0.39 based) but i cant find something near to what im looking for and i havent got enough time to programe my own synth. Im working in sounds for a computer environment, so they dont have to be very complex but with enough interesting qualitys. Some advice?some patch? Thanks in advantage, JosuÃ©.

Re: [PD] jpeg patchworks with Gem ?
by Ian Nault 06 Jan '06

06 Jan '06

I've had some fun with [pix_mix]... it's good for blending two pictures together... the only requirement is that the image sizes must match, which can be a pain for different sized images... additionally, if you use Gem to wrap a video file to a texture using [pix_texture] you can then use [pix_mix] to blend between the two videos... try playing with the homer.avi in the Gem tutorials, use two different instances of it running into [pix_texture] and then use [pix_mix] to blend them together... once i can figure out a way to dump to video (haven't gotten into PiDiP/PDP yet) i can show some examples, i've been playing with vnc2swf but i can't figure out how to up the framerate of it, it seems to be more gauged for video tutorials. I'll try to upload some screenshots of some of my Gem patches in action later this week... I have a sequencable sample looper (mainly for breakbeats) that uses a [phasor~] as a lookup, times the number of samples... i routed the [phasor~] to an outlet and made another patch that multiplies it times the number of frames in a video file, allows for some cool audio/video sync between a breakbeat and a video. For a fun time, have someone good with photoshop make a picture and then tweak it out, make a few different versions of it, then play around with [pix_mix]... i don't know if it'll be useful for collage/patchwork-like projects, but it's nice to mix between two or more images, especially if they're all similar. -Ian

readsf and filelength
by Ian Nault 06 Jan '06

06 Jan '06

"trying to get the absolute time of a file i want to play with sfplay/readsf~. Like a 3rd outlet which would give you the total length in samples, at loading the file. Found some old posts on the list from 2000 when the discussion arose around IOhannes writing zexy, but without success, and am wondering if this has been tried somewhen. Any Ideas?" I would recommend playing with [soundfiler] and [tabread~]. Read the help file for [soundfiler]; you need to send it a message with the filename to open and the array to send it to. [soundfiler] outputs the number of samples in the file when it loads it. I used this method to make a looping sampler that you can sequence out, using a sawtooth for lookup multiplied by the number of samples. Pretty nifty, I surprised myself when i got it to work. In my opinion it's a much better method than using readsf~, gives you MUCH more control over the playback. But really, it's a matter of preference, readsf~ is good for one-off sample playback. Hope this helps some. Peace, Ian

receiving more than one symbol
by altern 06 Jan '06

06 Jan '06

hi Just a suggestion, i was wondering if it would be nice to be able to receive more than one symbol at one atom. I know i could use several receive objects for this but i mean by using the property window. In my case i have some numbers controlling volume of different samples and i need to be able to change them individually when i load a preset, but at the same time i would like to be able to change all of them at the same time. I know this could be done in various other ways, but what i would like now is to be able to introduce in the receive-symbol field few symbols separated with a comma like : $1vol, generalvol not sure if this would be confusing, but in my particular case it is more confusing to have many wires connecting everything. bye -- enrike

hi Alexandre, you'll find attached an example that you might want to try, it's called: mozaic_photo.pd you have to launch pd with dyn~, pyext and Gem libs. sorry, i did not find time to comment the python scripts (nor the pd patchs btw). please notice that: - it uses imagemagick to compute image sizes. ("identify" command, fast). - thus it needs some plumbing to work under windows. - choose a few images first (try to use lightweight pics), in mozaic_photo.py change the rep at line 88: self.fphotos = glob.glob('/data/urban_man/photos/pietons/pieton_rouge*.jpg') please let me know if you found it interesting, what pbs you encountered, etc. best, vincent Alexandre Quessy wrote: >Salut Vincent, > >Oui, je serais intéressé par une telle patche.

using GEM in a collaborative environment
by Paris Treantafeles 05 Jan '06

05 Jan '06

Hi List, I was wondering if anyone knows of any projects which use GEM in a collaborative way. I've done some experiments with netsend and receive with more than one computer controlling a patch but in that case, the user doesn't see the end result of what they are contributing too. What I am interested in is a way for users to collaborate and see the results as well. Optimally, a user could see both what they contribute as well as a final result. I'd like to come up with a way to do this but thought it would be interesting to see what's been done in this area first. Thanks in advance, p
