Re: [PD] confused about $1 in messages
Thanks Jonathan for the detailed response and pointer to the docs. As a longtime (but somewhat sporadic) PD user this list behavior still becomes a bit fuzzy to me sometimes, and this helps make it much more clear. -s On Mon, Jan 20, 2014 at 1:30 PM, Jonathan Wilkes jancs...@yahoo.com wrote: I'm not sure why the people replying to you are feigning ignorance on how this situation could possibly be confusing. You're chopping off the word one with [list split] and leaving it intact on the other message; yet the dollarsign substitution gives you the same output in both cases. Furthermore, if you use [list length] on each message you will find the two message have a different number of elements. What you don't see, however, is that [list] objects like [list split] interpret incoming messages as list messages-- that is, they add the word list to the beginning of the message. Also, they prepend a list selector to the messages they send out (except for [list trim], of course). But we're not done. The selectors list, float, and symbol are special and do not get counted as elements with [list length]. Yet inside message boxes they _do_ get counted as the selector (i.e., the very first symbol atom in a message) when variable substitution is involved. Once you know those two details it gets a little easier to grasp. This is all further complicated by the fact that there is no dollarsign variable in Pd that can get the selector of an incoming message. So for list two three you can't get list with a dollarsign variable, and likewise for one two three you can't get one with a dollarsign variable. That's a real sticking point for new users, especially because they've no doubt already seen how seamlessly everything works when only numbers are involved. So I'd suggest everyone have a look at the help patch for [list], especially the subpatch labeled [pd about-lists]. In it, Miller Puckette-- the guy who designed and implemented this part of the language-- describes what is happening in some detail. In his explanation he questions his own design, even going so far as calling the very distinction you point out here ugly. It's not the easiest part of Pd to understand, and it's the reason why you're having a problem in the patch example you gave. But if you learn to use the [list] family objects when dealing with data messages it can makes things a lot easier. Since you know those objects will output messages with a list selector, then for everything other than a bang you're guaranteed that [$1( will work properly. -Jonathan On Monday, January 20, 2014 11:33 AM, Jack j...@rybn.org wrote: Le 20/01/2014 15:34, ro...@dds.nl a écrit : dear list, i'm confused about the $1 replacement in messages.

Re: [PD] Pd on Android
Seconding the dissatisfaction with real-time audio support on Android in general. I've only recently jumped on the android train (Samsung Droid Charge) and I've noticed that the only audio apps that are usable are of the sequencing / drum machine variety, because they don't depend so much on low-latency. Any apps where tapping on the screen is supposed to generate a sound exposes serious latency issues. I've heard that gingerbread made some changes to the available audio API, but supposedly they didn't substantially improve things. According to the people who know many of the latency issues are low-level (drivers and actual hardware limitations) that have as much to do with the device manufacturers as Android itself. One of the downsides of an open platform that runs on a wide variety of devices. I haven't had a chance to survey the situation with common audio CODECS being used on these devices and whether the drivers are available open-source, and/or could be hacked for better latency. I haven't been able to test much with libpd yet. So far any time any libpd-based app tries to access my microphone I get this crazy noise (actually sounds kind of cool, but definitely not the intended sound). I haven't tried building the latest from the repo, I didn't realize the binaries were substantially out-of-date (I didn't bother to check any timestamps). If that doesn't fix the issue I'll be sure to get in touch with the devs and see where the issue may lie. -s On Mon, Aug 29, 2011 at 4:54 PM, Hans-Christoph Steiner h...@at.or.atwrote: Hey Dan, I agree, Android's downfall is the poor audio implementation on the devices.

[PD] [PD-announce] gendy~ PD + Max/MSP object and libgendy 0.6.0 released
Hi Pd-ers, I've been working off and on for a bit on a C++ library to implement a variant of Dynamic Stochastic Synthesis, a technique developed by Iannis Xenakis. For a great history and more details of the original algorithm check out Sergio Luque's thesis [1]. The library is still pretty rough around the edges and more or less completely undocumented, but the PD object that uses it should be pretty functional. Included with the code is a helpfile as well as a gui that should make it pretty easy to jump right in. The basic idea of DSS is to describe a waveform with a set of breakpoints and interpolate between them to generate the actual audio signal. The set of breakpoints forms a single cycle of a waveform, and each time one cycle gets played, the breakpoints each move for the next cycle. So each breakpoint traverses a two-dimensional random walk. One improvement I've made to some traditional DSS implementations is the use of cubic spline interpolation instead of linear, which improves the aliasing considerably. It's not a truly bandlimited signal, but is differentiable. improves is obviously subjective, and linear interpolation is also available by sending a linear message to the object. The other modification is the introduction of selectable center waveforms that the breakpoints will gravitate towards. Right now I only have flat, square, and sine implemented, but I'm planning on including basic triangle and sawtooth as well. The h_pull and v_pull controls effect how much the breakpoints are pulled towards the center waveform. The external requires Thomas Grill's Flext library.

I understand that in the current implementation using s~ / r~ pairs is the only way to create a graph with cycles (or fake the effect of one, anyways), but it doesn't seem obvious to me that that is the only valid way to go about it. If they were just invisible wires then cycles would require other treatment, obviously, but it seems like cycles could be broken and turned into leaf nodes in the graph automatically, or by requiring the user to put a 1-block delay in explicitly, instead of letting the s~/r~ pair do double-duty and add the possibility for ambiguity as described above.

You can't get much more object-oriented than that. If you mean that the object-oriented approach has been implemented using C++'s grammar instead of having to invent yet another object system in C, you are right, and that can be a relief. However, this does not guarantee anything at all on the outcome of the project. Agreed that Pd's code is certainly organized in an object-oriented way, and the architecture that Miller has constructed to do OOP in C is extremely clever and definitely nothing to throw sticks at. On the other hand, there are structures that come for free when using a language that supports real objects out of the box (such as real polymorphism) that are difficult if not impossible to achieve in C. Much of ZenGarden is designed by copy+paste, and that's something that it doesn't get any better than Pd. Meanwhile, the author claims ZenGarden has « clean code », presumably to imply that Miller's isn't, but there's no explanation at all on what it means to be clean. I think cleanliness means no copy paste. I also think cleanliness doesn't mean using variable-names that look like this_is_the_array_that_contains_the_outlets_sorted_by_horizontal_position. I'm not ready to make blanket statements regarding the overall cleanliness of ZG vs. PD code, but there's definitely a significant reduction of boilerplate necessary to create an object, which seems like a step forward. I have some concerns about the extensibility of some of ZG's current architecture (the PdGraph object has a list of all the objects it supports hard-coded in), but it's still a young project with the architecture still somewhat in flux. Then the externals API... I don't think that was compatible with anything. It's a lot easier to port your Pd externals to MAX than to ZenGarden. agreed, losing the rich library of Pd externals would be a huge problem, and developing a flext-like abstraction layer seems intractable due to the significant under-the-hood differences. It also seems important to note that the ZG guys aren't trying to replace PD wholesale, but just to provide a separate runtime library that makes Pd patches more embeddable (within other programs, on other devices). The project was started by RJDJ, so I don't imagine that dynamic patching is a high priority. -s ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] Speaker protection abstraction
Most of my live performance work involves realtime processing of upright bass, and I find myself often using a lot of very short variable IIR taps (delays with feedback). I use either my 500-watt bass amp or the house PA as output. Right now I don't have any explicit patchage to make sure I'm not pumping out any signal that's straining the amplification system, and if I watch my speakers as I play I often see them popping in and out in a distressing fashion. I'm thinking I should start including some basic speaker protection into the output stage of my patches, mostly a limiter and highpass filter to get rid of any sub-audio and DC signal. Is this necessary? I assume that either the output of the firebox or the input of my amplification setup is AC-coupled and should be getting rid of DC anyways, but we all know what happens when you assume. Are other people using speaker protection patches? Anything more sophisticated than the classic [hip~ 5] before the output? -spencer ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Check out the SVN repo with svn checkout http://pdhmm.googlecode.com/svn/trunk/ pdhmm if you're on linux you should be able to compile it just by typing scons it's still pretty preliminary, but it should work on most midi files that don't have any SysEx messages in them. One of these days I'll clean it up and perhaps add it to pd-extended. -spencer ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] unclamped pix_subtract?
I'm trying to implement a background subtractor using pix_buffer to store the reference frame, and then subtracting it from the live video input, then using that subtraction as an alpha mask for the live video. The problem is that pix_subtract clamps the output at 0, but I need it to not clamp, and then I can take the absolute value. Is there a way to do unclamped subtraction of pix objects in GEM? thanks, spencer ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] HMM library - Chroma Analysys - Midifile dump (was: Midi File Playback)

I'm working on a score following toolkit using the GHMM library for hidden markov models, and as part of it I wrote a simple object called midiopen that takes a midifile and dumps all the data on its outlet. There's a simple PD patch called midiplay.pd that uses the midiopen object to play back a midifile using vline~ to schedule the whole thing. So far I've just written it for my own use and it's very hacky and I think it chokes on sysex messages, but feel free to check it out. The chmm object is something I'm working on to allow the creation of state machines with probabilistic emissions, and the selection of the most likely state sequence given a system and a sequence of emissions. It doesn't work yet, but it's a fun project. release early, release often, right? Compiling the whole thing requires libfftw3 and libghmm, but you can compile just the midiopen object without them. for those interested, there's also an object called chroma~ in there that takes audio input and each time it receives a bang spits out a 12-element list of how much energy it has received in each of the 12 half steps of western classical music since the last bang. check it out with svn co http://pdhmm.googlecode.com/svn/trunk/ pdhmm to compile on linux just type scons to compile on other platformsI'm not sure. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Is there a technical reason for this limitation? you can create a table the same size as your new blocksize, and use [tabsend~] / [tabreceive~], although i think that might bring in a one block delay, which might not be what you want. I could also use a delwrite~ and a delread~, which shouldn't introduce a delay if I force dsp calculation order using other subpatches.

[PD] PD on a DSP?
Has anyone had experience running PD using a dedicated DSP? I'm going to be starting an embedded PD-based project and my plan has been to use PDa on an ARM, but I'm wondering if I might be able to get more speed by offloading some of the maths to a DSP. If I used a floating-point DSP could I port mainline PD? I guess that PDa has to emulate the floating point for the message passing, which I suppose wouldn't be well-suited to a DSP anyways. Anyways, I'm just rambling... -spencer ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] timing question
Here's a patch that outputs the actual time of the bangs from a metro, and also shows the phasor~ clone generated using vline~. You can see that the actual time that the metro outputs is +/- 5ms (on my system), but the phasor has a constant period anyways! Craziness. So if I wanted to use PD to schedule some other program or device, would I want to send along some sort of timestamp based on the logical time to keep the timing tight? Perhaps this is a solution for some people who have been running into scheduling sloppiness when controlling hardware devices? It probably would be very doable to have an arduino do micro-scheduling of events based on a timestamp received along with the messages that are supposed to trigger the events. is anybody doing this already? -spencer --- #N canvas 193 278 652 300 10; #X obj 62 136 realtime; #X obj 62 189 -; #X obj 62 160 t f f; #N canvas 0 0 450 300 graph1 0; #X array \$0-waveform 1000 float 0; #X coords 0 1 999 -1 200 140 1; #X restore 395 68 graph; #X obj 62 217 print realtime; #X obj 201 162 vline~; #X msg 201 140 0 \, 1 10; #X obj 254 162 metro 100; #X obj 139 86 metro 10; #X obj 139 109 t b b; #X obj 167 7 tgl 15 0 empty empty empty 0 -6 0 10 -262144 -1 -1 0 1 ; #X obj 167 28 t b f f; #X obj 200 186 tabwrite~ \$0-waveform; #X connect 0 0 2 0; #X connect 1 0 4 0; #X connect 2 0 1 1; #X connect 2 1 1 0; #X connect 5 0 12 0; #X connect 6 0 5 0; #X connect 7 0 12 0; #X connect 8 0 9 0; #X connect 9 0 0 1; #X connect 9 1 6 0; #X connect 10 0 11 0; #X connect 11 0 0 0; #X connect 11 1 8 0; #X connect 11 2 7 0; - On Dec 17, 2007 11:58 AM, Derek Holzer [EMAIL PROTECTED] wrote: OK, now I've got it.
