Re: [PD] DesireData escaping code

Thus if you have list ah blah\ blah say there are three elements after «list», but resaving with current pd will put four elements after «list» because it will not save the backslash, so it will reload «blah blah» split at space. Stranger things will happen with semicolon, colon, backslash in symbols. Weirdness of braces is not so related to Pd's parser, but more about how it's uploading using sys_vgui. However, I remember I fixed it during the 2nd Pd Convention, but I don't remember how, though I know it has to have to do with savefn, because that's how DD sends all its patch data to the client. _______________________________________________________________________ | Mathieu Bouchard ---- tél: +1.514.383.3801 ---- Villeray, Montréal, QC

workaround for -batch -nogui delwrite~ etc bugs
by Claude Heiland-Allen 08 Aug '11

08 Aug '11

Hi all, The problem: Using pd -nogui or pd -batch, some stuff seems not set up yet when the patch is loaded, making [delwrite~] (among others) not work correctly. The workaround: Use dynamic patching to instantiate the real patch with a delay. Example: pd -batch -r 48000 -open workaround_loader.pd -send "workaround 50 500" pd -batch -r 48000 -open workaround_loader.pd -send "workaround 10 1000" Hopefully useful, thanks, Claude

stuff/synth
by Ludwig Maes 06 Aug '11

06 Aug '11

Hi, ive been playing around with the synth in the "stuff" folder and noticed some mistakes/strange manipulations, the weird thing is that it works out of the box. Originally I considered it as a serious example, but since certain things dont work properly or are strange I thought perhaps this was meant as a fix-me to learn from? i.e. as a didactical example for students to find common mistakes? I could be wrong of course so please point out what I dont seem to understand examples: *after dbtorms (_root_mean square), 2 extra roots are taken before sending it as 'amplitude' to the adsr, whose output is squared twice again... so what we get is that changing the input db by say 20, we are really only changing the output db with 5(=20/4)... I have no problem with rescaling midi velocities to sensible ranges but: one could just as well divide by 4 before the dbtorms so that the patch is more comprehensible *in the adsr patch (gadsr.pd) the attack phase is completely skipped (the rise message for the attack is sent to the line~ object, but instantly followed by the rise message for the decay, so that it rises to the decay amplitude), this is easily fixed by correcting the delay if this is a fixme, what other ones am I missing? yow!

reading a 4-channel aif
by Michael Zacherl. 05 Aug '11

05 Aug '11

Hello, for recording four channels I used [open -bytes 3 filename] fed into [writesf~ 4] in an earlier session. Now I need to split this interleaved sound file up into four mono-files for importing them elsewhere. I tried [open filename] -- [readsf~ 4] but just get digital noise. Since relying on its detection capabilities doesn't seem to work I tried to specify the parameters, starting with [open filename 0 200 4 3 b] . It changes the noise but doesn't deliver the proper audio stream. Admittedly I'm not sure about the header size How could I get this to work? many thanks, Michael. -- hear the colours of noise: http://blauwurf.at http://soundcloud.com/noiseconformist

Re: [PD] pd message order?
by Michael Matthews 04 Aug '11

> so standard objects have right to left ordering of outlet processing, but > what about send and receive for messages? if multiple objects receive for > the same name, which one gets it first? is there a triggerlike object for > messages, or should I send multiple messages each with a differentiated tag > like s bla1, s bla2, s s bla3 even when I send the same message? There is a way to sync data from multiple receives and it is to use the [buddy] object. [buddy] waits until it has received data at each inlet and then outputs everything it received through the corresponding outlet in the standard right-to-left order. It might not be a good solution in all cases since the receive objects need to be in the same patch window as the [buddy], but I have used it successfully for synchronizing receives within subpatches. [buddy] is in pd-extended, but I do not believe it is in pd vanilla. Hope this helps, Michael

Re: [PD] pd message order?
by Alexandre Torres Porres 04 Aug '11

I sometimes just get the receive as the "master receive", and then channel it down in sub receives that are numbered, and I use trigger. something like [r a] | [t f f] | | | [s a1] | [s a2] and then "a1" goes to where it first needs to be sent to. it doesnt look confusing in the code cheers

Re: [PD] Pitch Shift
by Alexandre Torres Porres 04 Aug '11

04 Aug '11

Thanks for the answers, I've seen the G.09 into an abstraction around and thought that th rjdj version could be it. It's also on the pdmtl package right? In which there's also a shifter based on the phase vocoder, anyway, the idea was to ask for something new. Thanks for the psola version julian, didn't know it, but as frank pointed, it may not suit me as I tried it and I prefer the phase vocoder version. And Pierre, in the link you sent it warns that it works best for small deviations, which can actually be good for me in one specific application, but not much on another unfortunately. I will try it, thanks! Anyway, I made a quick google on Stephen M. Sprengler's pitch scaler design and found no info on what the procedure is like :( By the way, I found this very interesting webpage about a pitchshifter~ object in Pd http://www.katjaas.nl/pitchshift/pitchshift.html But weirdly enough, I found no link to download it. By the fast look I gave it, it seemed to be an implementation based on the phase-vocoder process, right? But it also seems to differ in some way, could anyone tell me how exactly? And, well, most importantly, where is it??? thanks Alex
