[PD] freeverb crashes on new computer
Hi, im trying to run old patches on my new computer but freeverb~ always crashes , from time to time it stop doing sound and i get nan if i conect an env~ object after it. ive tried putting a clip~ -1 1 before freeverb~ but its still crashing Do anybody have an idea why is this behaivor and how to solve it?

[PD] [OT] SSE/MMX tips?
I am trying to code a simple operation using SSE2 instructions where possible. I have a feeling that what I want to do is just a matter of a couple of shufps and haddps instructions but I can't get it. Lazyweb please help! The operation is integration. I have a vector of 4 single floats (v4sf) and a carry-in float to start. For example CI F0 F1 F2 F3 5 1 0 10 -5 Yields F0 F1 F2 F3 6 6 16 11 So far iteration on plain floats seems to be the best I can come up with, but HADDPS is tantalizingly close to what I want to do. Any hints? Thanks, Bill Gribble ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] family affairs
Hello list, im trying to use the patch Frank posted some years ago in the list about parent- child relation with sliders. The idea is that with the parent slider you control the child values, but rather than just setting the child to the parents value the patch add the parents value in the childer sliders. but the patch has a limitation( bug? ): it just work when you have the parent value set to 0 , if you dont have the parent slider set to 0 and you change the childs sliders value and then the parent slider it wont work you are going to get jumps in the childs sliders. Which would be the best way to avoiding these jumps and make it work not only then the parent slider is set to 0? thanks here is the patch family_affair.pd Description: Binary data ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

But I don't remember whether I tried it or not. That's a speedup without even using MMX/SSE... theoretically, it can double the speed of a summation like this, and you can apply this boost to sum-of-products to get a certain amount of speedup too. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Hi Rick, your patch won't work. There are several wrong idioms, please take a look at the help file of [textfile]. The idea is you write each single line with the [add ( message and eventually write the whole text to a .txt file. The [print ( message in your patch is not needed. Also be careful while using [pack]. Remember that whenever it receives something on the first (hot) inlet, it outputs all the values it stored. In your patch [pack] behaviour is controlled properly. See also [pack] help file. A proper use of [pack] wouldn't require the [bondo] obj. cheers, M I can create the data but the questions I have 1) I keep getting a write failed. 2) how can I get the commas between the values? 3) is there a way to do leading zeros?

Well, it prints an error because there *is* an error in the patch. The author should never have converted a float to a symbol and expect to still do float calculations with it. Yes, I think it ought to be up to the external to implement its own symbol-to-float converter since there is no universally valid way of doing it. The same pattern will have different meanings in different context and Pd can't be expected to know what is expected in a specific case. Martin That sounds like a recipe for disaster, then we end up with multiple, incompatible ways of doing this. I don't think anyone is proposing that symbols like four get converted to 4, but only symbols like 43, 5.22, -234, etc. Things that can be directly converted from a char* to a float with a standard function. I think someone might well want to make an external that can take 'four' as 4. Or a symbol '4+2' that would become a float 6.0. And obviously Pd should not be doing that all the time because most of the time that is not the right thing to do. The disaster would be if Pd tried to guess what the user intends based on some general idea of what Pd is 'for'. For instance I've been working on an xbee external where I need to specify numbers like 0x0a060123 for the remote address. I do that by interpreting the symbol as a 64-bit integer internally but I would not expect any other external to do this unless it needs to. Otherwise the user would have to manually convert the number (which is conventionally given in hexadecimal form) into a bunch of decimal numbers small enough to be represented as float and then the external would combine them internally. Martin Yeah, I agree, I have no problem if someone wants to make an externals that interprets 4+2 or four as 4, but it doesn't seem like something that should be in the core. About hex 0x form, that could conceivably fall under the anything that looks like a number is a float, as least for programmers. In most programming languages, 0x10 is just a number like 16. .hc If you are not part of the solution, you are part of the problem. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Once I thought that with some commutativity you could speed things up like this : (f0+f1+f2+f3)+(f4+f5+f6+f7)+... can be rearranged as : (f0+f4+...)+(f1+f5+...)+(f2+f6+...)+(f3+f7+...) But what I said does not apply to your case, because you want a scan, whether I didn't really read and assumed a fold. I don't know how to optimise a scan. This is really interesting. Your compiler probably knows how to optimize this kind of information. SSE3 is really about memory allocation. The instructions pack floats into a bigger section of memory. In SSE3, this means 4 floats in a 128-bit single operation. SSE 4.2 has 256-bit wide (8 flops per clock)--the latest increase in single-threaded computing power is in favor of single-precision float (lucky for Pd-ers) ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] [OT] SSE/MMX tips?
I noticed that your suggestion did not apply, but assumed it was a subtle riddle taunting me for an offtopic post! I think the best I can do is 2 vector adds and 2 shifts in place of 4 float adds per 4 floats. Not much of a savings, but with the loop and fetch overhead it may be worth it. I'll benchmark and see! It's really just for fun anyway.

Re: [PD] OSC Confusion
Have you tried [O] | [import mrpeach] then [udprecieve ] (the is whatever port your are using), | [routeOSC] etc?

Re: [PD] OSC Confusion
hello, mrPeach OSC objects, and many other ones are stuffed into pd-extended's nightly builds, you can find them at this url: http://autobuild.puredata.info/auto-build/latest/ - Jim Aikin midigur...@sbcglobal.net a écrit : I've been using Pd 0.41.4-extended in Windows 7 64-bit.
