I hadn't seen that one yet. The development platform with Faust is completely foreign to me--I don't think I can reply back to you with anything good. Probably, if we come up with anything in the way of top-down design, we should be able to apply the same framework to different platforms and make comparisons. Chuck

Re: [PD] pd~ for Max
by marius schebella 21 Feb '10

okayyyyyyyyy! so what I have to do is: start the help patch with max4, then open Options - DSP Status (If I try to open the panel later, I get an error saying error: Bad file descriptor) then I had to replace the opendialog with a simple message starting with "/Users/marius...", as opposed to what I got before "mac_hd:/Users/marius...". and then I clicked on this message, pd would start up and spit out a message with a lot of zeros. and then I start sound as you said from the DSP Status window. hmmm... actually trying the whole thing again, it now works by just starting pd with the pddir message and the start message and *then* clicking on ;dsp start. but only once, I cannot stop pd and start it again, that brings me into freeze mode again.. ah, it works if I turn off dsp in max before stopping pd, and then start it again, and then turn on dsp again. marius. 2009/9/1 Miller Puckette <mpuckett(a)imusic1.ucsd.edu>: > No, I mean the Max thing...

Re: [PD] 'synced' number and slider
by Jonathan Wilkes 01 Feb '10

01 Feb '10

I attached a modified version of your patch to show what I mean. On the right, you can look at the patch and figure out the behavior before you scroll the gatom box (important if you want to make sure you're avoiding a buffer overflow). On the left, you have to read the source code for those GUI objects to figure out what's going to happen. Judging from your original patch, I think you assumed that sending a float straight to the [nbx] would update the value in the slider (so did I). This turns out not to be the case: the two GUIs are only bound together if you change the values on one of them using the mouse. If someone who reads and understands c better than me can explain why the iemgui magic works as it does, I'll be happy to document it. -Jonathan --- On Sat, 1/16/10, Rich E <rich.eakin(a)gmail.com> wrote: > From: Rich E <rich.eakin(a)gmail.com> > Subject: Re: [PD] 'synced' number and slider > To: "Jonathan Wilkes" <jancsika(a)yahoo.com> > Cc: "Lorenzo" <lsutton(a)libero.it>, "IOhannes zmölnig" <zmoelnig(a)iem.at>, pd-list(a)iem.at > Date: Saturday, January 16, 2010, 8:38 PM > You can still send the set message directly > to the inlet of the numberbox2 or slider and it won't > effect the other.

Re: [PD] latency solutions... and then some
by Marco Donnarumma 01 Feb '10

01 Feb '10

> > His set uses an electric bass through Pd. My guess is > that even the un-processed signal goes through Pd to avoid echos or comb > filtering due to latency. In my (2 cent) experience to let the un-processed signal go _through Pd_ is still unsatisfying, because anyway you have to deal with some latency hiding around. Instead I usually let my external soundcard output a small amount of "direct monitor". This way my clean signal goes through the hardware to the PA with no latency (or at least a fairly un-noticeable latency), then the processed signal/s get overlapped with the minimum latency I can get. This is the cheapest and more satisfying workaround I found so far, even though it's not reliable in every condition and setup. Besides, as already said, when you trigger digital effects with an external hardware you can add more latency; to avoid it, I analyze the un-processed input signal, recognize the notes being played and trigger effects when a note is recognized. Thus I just deal with the latency created while the un-processed input reach the analysis patch. At the same time I route the un-processed signal to the effects bank. Not rocket science but hope this helps. M

Quick processor question
by Andrew Faraday 01 Feb '10

01 Feb '10

Hey Folks I'm aware that cutting the signal from an [osc~] will not actually reduce it's processor drain, nor, to my knowledge, does the frequency affect CPU usage. However, does anyone know if it'll take less processor, while not using the output of the object, to give it an argument of 0? That is to say, while the output has [*~] + 0 that zero is also set to the frequency of the [osc~] will this be any more efficient?

Re: [PD] Pd-GUI-Rewrite 0.43 status: usable
by Jonathan Wilkes 31 Jan '10

31 Jan '10

I downloaded 0.43.0-devel-20100119 (windows) and found a few things: 1) A patch like the one I attached used to have no scrollbars (all the way up to the dev version I downloaded on the 11th). Now it has scrollbars. 2) In the attached patch right-clicking and getting "Properties" or "Help" doesn't work properly. For instance, if I right-click on [bag] in the upper right-hand corner and choose "Help", it gives me intro-help.pd. If I right-click the message box with the selector "clear" in it and choose help, it gives me text-help.pd. 3) For menu->Window: is the tree structure represented solely by indentation? There was some problem I was running into with the previous build where selected text in a msg box sticks until you force a refresh by minimizing/maximizing, but it looks you fixed it. -Jonathan

soundfiler resize failed
by William Brent 30 Jan '10

30 Jan '10

With larger sound files, I've seen soundfiler fail to resize arrays, even with an appropriate -maxsize value. For instance, with a .wav file that's 45205253 samples long (about 17 minutes), this message produces a "resize failed" error: [read -resize -maxsize 4.52053e+07 test.wav sf-test( But if I resize the table to 45205253 points directly beforehand, a regular read message to soundfiler loads the complete file properly. I've searched the list to see if this has been brought up before, but didn't find anything... Am I missing something? -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com

efficiency savings?
by Oded Ben-Tal 30 Jan '10

30 Jan '10

I started putting together elements of a patch that I worked on separately and I'm getting sound droopouts. It seems I'm simply asking Pd to do too much for real-time processing. I started making the code more efficient by removing number and gui objects that I used for debugging and used switch~ to shut off audio processing in windows when not used. Any other general suggestions? Is there a method of finding out which parts of the patch are most demanding? thanks Oded
