Re: [PD] patch wanted: loop station
The way to deal with this in real-time is to fade in for a short period at the start, and fade out at the end. In order for that to respond in real time, I've found a good way is to delay the audio stream by a tiny value (e.g. 5ms) then fade the audio at 5ms - 1 audio block (about 1.46ms). That way, when you hit stop on the sample playback object (e.g. tabread4~ or xgroove~) the audio stops, but the 5ms delay means that the fadeout starting at that moment will happen before the audio you hear stops (because it is delayed by 5ms). I hope that makes sense. Patch enclosed!

Re: [PD] Legal restrictions for apps
Hi Dan, Miller et al. I'm still somewhat confused about the LGPL issues with regarding apps. Say I make an app that uses LibPd, and include an object or library that is licensed with an LGPL license.

Re: [PD] Pure Data, libpd, help
Hello Andrei. The Ninja Jamm patch has moved on a bit since then, but there are some things you should note. 1) Events can be encapsulated but audio paths cannot if you want the greatest efficiency from your target device (e.g. iPhone 4 - the minimum platform for Ninja Jamm). But try not to encapsulate below one level below the master patch, even for event-based subpatched, if you don't want to glitch. 2) you will probably have to write a few externals of your own if you cannot get the functions you need from vanilla Pd, and these need to be wrapped into the compilation of the app. Look at http://pdstatic.iem.at/externals-HOWTO/ for more info on how to write an external for Pure Data. Alternatively it is worth checking out the rjlib material from RJDJ at https://github.com/rjdj - v.good abstractions! I don't make the GUI for Ninja Jamm but... 3) the way a libpd patch is controlled by a GUI is by send and receive objects in Pd. In my experience it is normal to make the objects in the GUI non-callback - i.e. if the GUI objects receive a message from Pd they do not send it back to Pd, but if a message is sent to the Pd patch it can send one back to the GUI. I hope this helps.

I recently discovered your work for the Seeper Ninja Tune app. I would like to learn more about making and integrating Pd patches in apps using libpd, to get in touch with apps developers and propose the addition of procedural audio to their apps. I had a look at the screenshot of the patch (http://createdigitalmusic.com/files/2013/04/np-PD-patch-of-Ninja-Jamm-code-audio-engine.gif), and I found it striking that so much is on the main patch without using encapsulation. I would appreciate if you could share your experience about current limitations, challenges related to communication between Pd and the operating system, and maybe other issues you have found essential in integrating Pd as audio engine. Please reply whenever you can spare a minute, it's not urgent, but actual insight to the development process and understanding of it is very valuable to me.

That's useful, but up until recently you had to create a second instance of Pd from the command line anyway, since OSX would show you the instance you already had if you tried to open it from the operating system. Or...have I missed the point? My friend and collaborator always needs two Pd's, one for Gemnotes and one for audio processing, to play my musioc...and we wrote a BASH script to launch the gemnotes one after the audio one was set up. well, personally most times, when developing, I need to create abstractions and use global variables just to experiment with stuff. And if two instances of Pd are opened when you don't want it, it can be very annoying. Even worst scenario when you are teaching, student might open 4 patches at a time, and as 4 Pd instances are launched, and it's a mess. Ah yes, students. Student: But why can't I just double-click on the patch? It works for everything else? Tutor: Because the audio driver will only work with the first instance of Pd you opened.

Re: [PD] karplus drum?
Years and years ago (1996) I made a CSound script, with the control rate set to the same frequency as the audio rate, and used it to generate FM Karplus-Strong. A sine wave modulating a Karplus-Strong string model's frequency. I swept the modulation frequency through the experiment, while generating regular impulses to pluck the string and there were indeed some quite snare-like sounds in the more dissonant carrier/modulator relationships - i.e. where the ratios were more like 32:31 than 5:4. The carrier being the KS string model and the modulator being the sine wave. If you're doing everything with vd~ then you can emulate this. I think I still have it on one of my hard drives, but I don't know which or where. I'll try to dig out the audio tomorrow...(today? for some reason I am awake at 6am) and possibly even the CSound orc/sco files !?!?!

Re: [PD] Error: invalid command name pd
Hi Jonathan, OK, here is a rundown of what I did to get tot working. Remember that I added elements FROM the svn version TO the downloadable verision from Krzystof's site. in the miXed/shared/hammer directory: gui.c needed all pd [concat etc] statements changed to pdsend [concat etc] as was advised. file.c and file.h: I changed the function void hammereditor_open(t_hammerfile *f, char *title); to add the third argument: void hammereditor_open(t_hammerfile *f, char *title, char *owner); and copied the relevant function from the svn version into file.c, overwriting the version that was there. Also, in the downloaded tarball from Krzystof's site (I hope I got his name right) there was an extra function I added to file.h and file.c: void hammereditor_setdirty(t_hammerfile *f, int flag); from the svn version. NOTE: I am only pasting the file.h declarations, so you'll have to check the files out for yourself. But I am including a tarball of only the files I changed. I'm pretty sure that's all I did, but the annoying thing about the download was that cyclone had its own separate copy of the shared/ directory, so each file had to be copied into it as well. That's why you'll find a duplicated of the files in the cyclone folder, where none exists in the svn folder (again - I've removed everything I didn't have to change). Also, I made sure I unzipped both the downloaded cyclone source file and the downloaded toxy source file into a folder I called miXed somewhere else from the svn copy on my hard drive. I don't know if it made any difference, but they were in the same folder I guess. That's what I did. I didn't have to edit the Makefile.common in the root miXed directory, as I should expect since my m_pd.h, m_imp.h and g_canvas.h files I always copy to /usr/include when I install a new version of Pd. But I also notice that in the download versions of cyclone and toxy there are copies of m_pd.h and m_imp.h floating around!

Re: [PD] Error: invalid command name pd
I think my problem with this, and when I tried it last time it was the same, is that I get these compile errors even after I've pointed the PD_DIR setting to either: /root/software/pd/src/pd-0.44-0 or /root/software/pd/src/pd-0.44-0/src When using miXed from the subversion repository. I notice if I download cyclone from http://suita.chopin.edu.pl/~czaja/miXed/externs/cyclone.html and toxy from http://suita.chopin.edu.pl/~czaja/miXed/externs/toxy.html ...they compile OK. So there is something wrong with the svn version of miXed perhaps? Now I still get my tcl errors from [tot] but I can have a go at fixing the tcl code now. Cheers, Ed I think the problem is with [tot .] from the miXed library. Does anyone know how to compile it? It's causing me a headache. Typing make from within the miXed library from the svn repository comes up with errors where it can't seem to find basic functions, e.g. some lines tot.c:(.text+0xbcf): undefined reference to `gensym' tot.c:(.text+0xbff): undefined reference to `canvas_getrootfor' tot.c:(.text+0xc17): undefined reference to `canvas_getrootfor' /tmp/ccctv252.o: In function `tot_getcanvas': tot.c:(.text+0xc5b): undefined reference to `canvas_class' tot.c:(.text+0xc69): undefined reference to `pd_findbyclass' tot.c:(.text+0xc79): undefined reference to `glist_getcanvas' tot.c:(.text+0xcb7): undefined reference to `loud_warning' tot.c:(.text+0xd48): undefined reference to `loud_error' some more lines Look inside Makefile.common and change the line near (or at) the top that sets PD_DIR. It looks like it's supposed to point to the src directory, but I'm not absolutely sure about that. then try make clean and make from inside the miXed directory. If that doesn't work, add to the line in Makefile.common that starts with INCLUDES = . You'll want to add a something like this: I/path/to/the/place/where/m_pd.h/lives Then make clean and make. Now it should create everything without error. All your binaries will be located inside miXed/bin, including [tot] which I guess is what you're after. At this point, you have to do this: 1) Run your patch 2) Note the errors and place in the tcl code where they happen 3) From the miXed directory, grep -r part of the erroneous code that calls pd instead of pdsend 4) Note the filename that grep returns 5) Go to the corresponding line of the offending file and change pd to pdsend. Also, I think the old pd tcl proc had an escaped colon after it, whereas the pdsend proc doesn't require one. I'm not sure whether that makes a difference or not. 6) make clean and make 7) repeat until you don't get any errors. If you're feeling generous, do this for all the toxy c files as well as the test files, until the entire library actually works with pd-0.44, then diff against the old toxy and post so we can update the code. Let me know if you have any problems with getting your patch to work. -Jonathan It gives similar outpuit for tot, and for pddplink ?

Whoa! I wonder - this was a libpd app I made, and it definitely made a difference putting all the DSP on one layer, but it was complex and I may have missed a trick here. It runs on an iPhone, and I wonder if there is a difference in how that works. resolving abstractions and subpatches with audio dropped the CPU load on an iPhone 4 from 132% to 71%.

I haven't made any measurements but theoreticall at least there shouldn't be any difference. i once did make measurements, and they showed that your assumption is correct. or at least, it showed that it *was* correct at that time. this was on a P2-400MHz in 1998 or so, where a 16 channel spatialization patch would eat about 95% of the CPU - regardless of whether you used a single huge patch or organized the code into subpatches/abstractions. eventually i went for using abstractions, and let the PC run at 95% for the 2 weeks show. I once made some informal tests to measure the overhead of [switch~]. It turned out it is quite big and if you're running hundreds or thousands instances of [switch~] you probably gain nothing by turning DSP off in subpatches. I don't know what the sweet spot is it seems using [switch~] is only worth for subpatches with a minimum amount of (DSP) complexity. Roman I don't know why this is so... When you add a [switch~] object, it adds a prologue and epilogue around the perform routines from each object in the subpatch. The runtime behavior is just like [block~], except when the patch is switched off, the switch prologue returns a pointer to the epilogue, instead of the next item in the dsp chain (don't quote me--I may need to read some code to find exact behavior, but that's the gist of it). To me, this is pretty minimal and reasonable. Maybe there's an unintended consequence like cache misses when skipping over part of the dsp chain.

Re: [PD] electro-mechanical piano (player piano) - Arduino, Solenoid Issue
Check Ohm's law. V=IR, so the resistor you choose is the voltage you provide to the LED divided by the current it draws. e.g. if the LED draws 20mA and you power it from 5V, then the resistor you need is 5/0.02 = 250 ohms in series with the LED. This current is drawn from the positive voltage supply through the resistor and then the LED, and then the transistor.

In this case, the on-time on the TLC corresponds to the off-time on the solenoid. Also when the arduino reboots and every time the BLANK is issued, every solenoid will act for a very short time.

In this case, the on-time on the TLC corresponds to the off-time on the solenoid. Also when the arduino reboots and every time the BLANK is issued, every solenoid will act for a very short time. This can be a big problem in your project. I did this for a 96 channels motor+led strip system, and I regret not using PNPs instead.

Re: [PD] How to reduce CPU use on unused subpatches-abstracts?
There is another catch with the CPU usage, which I only learned about while building a big libpd app. If you have subpatches within subpatches this is usually not a problem with control data. But, it really helps a lot within a patch if you put all the DSP objects on the same layer (i.e. without and audio subpatches). Of course, the most CPU efficient patch will have no audio subpatches at all. I think the reason is that subpatch audio is calculated in a block within the subpatch, and this means a separate process from the master patch and takes more CPU time. I'm not 100% sure that's the case, but intuitively it seems to make sense.

Hey dude, I got the libPd problem fixed. non-audio events need to be aligned with block boundaries in the DSP chain. Otherwise you get single block loops in the audio output (buzzing) that you have no control over. Of course this happened with my custom clock generated from a phasor, (16ths, 24th notes etc) and I wrote the external to counteract clicks in the audio generated by the delay between an audio event and it's Pd clock time (catch 22, but I bypassed it eventually).

Re: [PD] libPd hanging audio and other questions
Hi Dan, Thanks for your help. I know they're holding off the rewrite in OF 7 due to time and budgetary constraints, but we think there was another reason why it kept hanging. A, external I wrote in C gives out sample accurate events (rather that block-aligned ones) as well as a signal. The outlet_float statements were embedded within the DSP loop. You can get away with this in Pd running on a computer, but it doesn't work on an iPhone. This may be bad programming (I'm not sure - I taught myself) but it does cause Pd to crash when DSP is turned off in ofxPd on iOS. The DSP never got turned off and a chunk of audio was left looping, regardless of what the DSP chain was supposed to be doing, both in the simulator and on the device. Anyhow, I re-coded the external using a Pd clock to block-align the events and the problem went away. And I have finally learned to use clocks in Pd external coding! Ah, what fun I'm going to have ,-) Does anyone know what the standard blocksize for writing RT audio from memory to the SD card in an iPhone is? That's another problem we're facing. Drop-outs happen when recording, and we think it might be because we need to deal with the audio in certain size chunks, but we're not sure what that size might be. And do they have to synchronize with Pd's block size (i.e. 64 samples) in order for this to work?

Even just to generate a file, it would be a good idea to be able to search the libs and find out what you need to [import] to get a patch made on pre 0.43 Pd-extended to work.

[...] * new standard library that is larger and more consistent than what's in vanilla, things like all math and logic objects both message and signal included, rather than needed to load a library (i.e. zexy) for some of them. It would prioritize correctness and consistency over backwards compatibility. That's a royal waste of your time. I'm certain you wouldn't advocate _moving_ objects from various libs to one standard lib-- as that would break backwards compatability-- so you must be advocating copying them. Both would have the direct affect of confusing users-- the former by _breaking_ all kinds of help docs, tutorials, and lots else that's more or less part of the standard Pd world at this point; and the latter by returning two results in a search for an object that happens to be in the standard library. Either is also a royal waste of the users' time. If there are specific objects inside zexy or hans that need to be superceded by an object with a better design in order to get more consistency, or if there are objects that haven't been created yet that would add needed functionality, let's talk about those cases. But [import hans zexy lib_to_be_coded] is a perfectly reasonable interface for loading 90% of what the user needs, so let's not go breaking stuff for the sake of theoretical consistency. For the other 10% it's just fine for the user to search for that functionality and use the prefix that is shown in the search results, or click the info icon to read about the relevant library, or use [import], or do all three. Yes, it'll be a chunk of work, but I strongly believe it'll be worthwhile. Python3 is a good example of this kind of thing. All the existing libraries would remain as they are, so backwards compatibility would be fully available. I agree theoretical consistency is not a worthy goal, that's not the point here at all. [import zexy] is a good example. Let's say a user is looking for objects to make and manipulate symbols, how about calling tat library symboltricks or something descriptive, rather than an arbitrary name 'zexy'. In python, if I want to work with URLs, I load a 'urllib' or maybe 'urllib2'. The point is that the old way of organizing libraries was around the author, not what the library does, like zexy. Newer libs like iemguts, pmpd, log, etc. are organized around a topic, and that makes much more sense. That's a very widely established paradigm for libraries across basically all languages. Honestly, in the long run I think this will be less work than maintaining the system as it is now. There are so many exceptions and quirks that is really is hard to make progress because some forgotten quirk comes back and bites you. * no libraries but the standard library loaded by default. * the possibility to load distro profiles for compatibilityYes, it'll be a chunk of work, but I strongly believe it'll be worthwhile.

In the search plugin I'm judging vanilla objects based on whether the help patch is inside 5.reference, and returning them first in the results. I asked you awhile back if the subdirs in doc are subject to change and you said they were a standard part of Pd that wasn't likely to change. If want the vanilla lib for the sake of consistency, you won't get it because the vanilla help patches must remain in 5.reference.

[PD] Fw: Help to load sound
Hi Romain, Please also read the other posts about the -maxsize option for soundfiler. Sound quality for readsf~ is as good as it gets. The only difference is it reads the ound from the disk as it is playing, and this is better in that you can load a soundfile while playing the patch without dropouts. When you load a file into an array or [table] using soundfiler, the audio switches off for a moment, so you have to load all sounds before you start playing. With readsf~ you can load a new sound in the middle of a performance without affecting the audio.

May I make a suggestion?

By far, that is currently the fault of the software-- the documentation is currently too slim and core pd building blocks (and interface) too crude for the question how do I find more objects to be anything like an ancillary question. A static out-of-date list is better than nothing, but as far as potential dev energy I'd really rather see that put into core docs like the ones listed on the bug tracker, which are extremely lacking. That FLOSS list will hopefully become obsolete, but the help docs won't-- even if they're dropped from Pd-extended they're still publicly available. -Jonathan While I have agreed and disagreed with various points in this discussion, I think Jonathan's two paragraphs above sum up my feelings on this topic too. Jonathan has put together a really great system for help from the meta data to the search plugin, now we need to put actual content and meta data in our help patches and it'll all be findable in a multitude of ways. All this could even be used to generate the static listing in the FLOSS manuals: just take the object name, then get the library and description from the [pd META]. Yeah, and we need the spec for [Pd META] to be known. For devs maybe en entry in the externals HOWTO? There are some great ideas here that need further investigation. 1) Generation of static web documentation from [Pd META]. It's the only way such online documentation could be kept up-to-date as Pd is indeed a moving target 2) This would require [Pd META] to contain more information than just the library name, author and version. Since this is already universally applied across Pd extended, it's ready to be modified and extended. Does this sound like a good idea?

Re: [PD] GUI overload
One other occasion where I used to have the same thing happen to me which might shed some light on the situation. Remember Brazil? I tried all evening to get my GUI-intensive patches working. Fortunately we did, in the end, get some music. It was all down to that pesky firewire interface, using Jack. I had to run Pd in -rt mode, and I have found that running Pd in -rt often causes the GUI to seize up completely in my patches, in exactly the same way as it did for the latest one. I don't use Jack any more, nor do I ever run Pd in -rt mode. Without -rt I find I can do things like create a new [table] object and copy audio data from a recording of the [adc~] into the table, without any audio dropouts.

Re: [PD] translate the Start Here! page
OK, no need to fight. This is about a version of Pd-extended that has been a very long time coming, that had many issues to resolve, that went offline and was unavailable at the start of the workshops I teach. I also can't get my students to download a version of Pd-extended that isn't finished and won't run on their machine. This is their first experience of programming. They'll give up straight away! It sounds like it will be finished soon, and then we can all relax. Until then anything I can do to help my students achieve some traction with Pd, including pointing to a list of objects - until search is finished AND in the release version, is pedagogically valid.

Learning Pd from scratch is not easy unless you are already a computer scientist. How do I know what the objects are called is I agree, the wrong question in so many ways. Pd is basically just rectangles containing words, connected by lines. Each box should do one thing and do it well, to draw from the unix philosophy. Lines connect the input of one box to another so that complex problems may be solved by combining many simple, clearly-defined building blocks to one another. Aside from the particulars of controlling the flow of data through the diagram, what other question is there than, How do I know what the objects are called? However, 80% of my undergraduate students basically give up at that point if they can't find the answer, and probably 60% of my masters students, often after saying I hate Pd. Of course they might also have just found out what happens when you try to click Undo more than once in a row. Or they projected a patch on a screen for a demo and tried to enlarge the patch by making the fonts bigger, and Pd mocked them by making a mess because well, they didn't tell Pd to also scale the x,y positions and Pd isn't about to make any assumption at all about what the user wants because then it would be coddling them. Also they can't change the colors. Also in tk 8.4 the fonts hurt their eyes. Also the tk menus respond to clicks in a slightly different way than native tk menus. Also moving an array (which also is limited to black and white) not only causes dropouts but animates with speed similar to an Apple II. Also every time they load a soundfile they are in danger of a dropout. Also patches look slightly different on different machines so that Alice may send perfectly designed patches to Bob but Bob sees overlapping text and wonders silently why Alice is so sloppy. Also any time they consider improving any of this behavior they are faced with a graveyard of revisions by people much smarter than they are which are way more elegant than anything they'd ever come up with. Pd _clearly_ hates them from their perspective. Provably, because as you said they're already using advanced software that has tons of quality documentation and teams of devs devoted to caring about how well-designed the interface actually is. And let's hope they don't come on this list and see the general ethos that while Pd is barebones, real men build patches from the ground up and eschew pre-fabbed solutions. (Again drawing from the unix philosophy.) Fine, but somehow that translates into a programming environment that's less accessible for people with vision problems, and a single undo history? That's absurd. I wouldn't criticize them for not being Nelson Mandela

I think it can be both, but I don't want to kick away the ladder... Perhaps the problem lies more with standards for documentation across the whole community - it's never going to happen (remember Pdpedia?) because the Pd community can be somewhat anarchic. Hats off to Hans - making Pd-extended work is like nailing jelly to the wall I guess. There are some small things we could do. For example, a description of what lies in each folder of externals and what they are for may well be enough, followed by a list of objects. My students are _scared_ of Pd because it is so utterly different to anything else they have ever engaged with. A bit of documentation that isn't in Pd itself eases the pain somewhat. A static web page will never be up-to-date since the pd externals folder is always a moving target. But it is better than nothing. It was really hard persuading students to learn Pd when Flossmanuals didn't exist. It's still hard, but it does open some doors to my students.

Re: [PD] mastering to vinyl live w/ pd
Hey Mark, RIAA - the original RIAA curve is the one, forget the variants, especially the IEC variety. It's a high-frequency pre-emphasis filter that overcomes the inherent surface noise of vinyl by boosting the HF, and reducing the. bass so that the needle doesn't jump out of the groove. Also, the curve you most commonly see is the reproduction (de-emphasis) curve (the one which slopes downwards) - this is irrelevant, since anything you play the vinyl back on will have this frequency response built-in. The recording curve is the one which matters - I think it should not be too hard to implement the original equation in C, or even using exp~ or fexp~ - just to send it to the lathe. The problem is that the mechanical nature of vinyl means that, a standard 6dB/octave single-pole highpass filter won't work, because the amplification needed to restore the bass would be too great. It's a sort of kinked highpass filter. See this article: http://www.stereophile.com/features/cut_and_thrust_riaa_lp_equalization Also, the mix must be mono compatible. This mostly means keeping bass frequencies in-phase and trying to make everything below about 220Hz mono. Metastudio 4. I call that a lost metastudio, because I variously did and didn't distribute (leak) it on a personal basis (I was slack/busy, I had kids, you know...)

Re: [PD] GUI overload
OK, well in fact the problem was not arrays updating. It was all the other GUI
objects (sliders, mknob, num2 etc) that would freeze, and this is running on
GNU/Linux. This was a real problem, since I could change them with the mouse,
but the results of the change were not shown (e.g. the pattern-number in one of
my sequencers).
Changing sys_pollgui() did fix this, so perhaps what we are actually dealing
with is two separate issues, one concerning arrays and another concerning the
rest of the GUI.
Ed
I tracked down the commit that seems to be causing the problem that Porres
reported. I think its a totally different problem related to Pd-0.43's new
portaudio implementation. It does not affect GNU/Linux, which doesn't use
protaudio. I haven't tested it on Windows.
https://sourceforge.net/tracker/?func=detailaid=3573542group_id=55736atid=478070
Ed, if part of your problem is arrays that stop updating and you're running
on Mac OS X or maybe Windows, this might also be affecting you.

that sys_poll_togui() never

Re: [PD] Licensing issues (was rjdj is gone, robotcowboy is coming ...)
My 2pence worth: Working with libpd for an iOS application, to be distributed through the app store: I found it necessary to 1) re-license my own library of externals ekext to BSD license. I know Apple has a problem with GPL - or more specifically, GPL has a problem with closed-source code. Miller's original Pd was licensed to MAX and became MSP (oh, the irony) and this could only happen because Pd is BSD (not GPL) licensed distribution. 2) code new externals when I wanted some special functionality, such as a resonant filter (mvcf~ in the ekext subversion repository). This code was released BSD. There is so much in the rjdj library that can help, but a lot of lateral thinking is needed if you're used to Pd-extended objects. For example, I use [goto $1, this( a lot with [msgfile] to organize lists of data, sequences etc. You can't do that with [textfile] so you have to: [f] | [t b b f b] | | | \ | \ | \ | \__|_\___ | | \ \ | [until] | \ \___ | \ \ \ | \ \ [textfile] | | \ [0 ( [1 ( \ // [spigot] ...perhaps there is another way? 3) If you organize tables with a hierarchical naming system then you can avoid most of the woes of using arbitrary symbols (unless you are using readsf~ for example, where file names have to be stored). For example: [t f b] | \__ | \ [f] [f] | | | [makefilename wav-%s-%%s] | / | [set $1( | __/ |/ [makefilename not-set-yet] | [set $1( | [tabread4~] In the [makefilename] object, %%s becomes %s when it's output. s becomes %%s, so you can have more levels of hierarchy for naming conventions. 4) If you ever need song position pointers per bar or something, the [sieve] external from ekext is invaluable. For each bar number you can store another number containing a parameter (such as a table name etc). It's BSD licensed and ready to go. Apologies but I can't post the source code for the app I made for legal reasons (! - that's the rub) but these are some tips. While I believe in GPL and have benefited a great deal from it's existence (Linux anyone?) I think it would be a good time to start getting an libpd add-ons library of externals together, that developers didn't mind being used for commercial projects.

Re: [PD] soundhack
[declare -path path/to/library] this only takes effect when opening the patch. This method has several advantages over the path preference of the application. For instance that you can redistribute a patch with a folder where the abstractions are in and you can declare that relative path in your patch. Yes, you can do that. Or alternatively...I am working with a percussionist who has to run his patches on a Mac. I have a version of the external I am using for a Mac inside a folder ext/ which is inside the directory that contains the patch. Instead of typing the name of the object into the object box when it is created [gemnotes_counter] I type... [ext/gemnotes_counter] and the external is always the right version, since I make sure the extern is distributed with the patch. I also have versions for Windows and Linux in the same folder, so in theory I could run it on any machine...

Re: [PD] pd-extended 0.43.1 - objects not loaded
Hi Athos, hi, I installed pd-extended 0.43.1 on my ubuntu 12.04 machine. I'm experiencing a strange behaviour: at some point it started failing at loading some pd-extended objects like mux~ or ezdac~. In the log I see that all libraries are loaded correctly.

Ed I thought to try with 0.42 but as far I understood there's no easy way to install it on ubuntu precise. Did anyone experience the same behaviour?

Re: [PD] opinions on the issue of concurrent implementations (was: getting sample rate of file loaded into an array)
We should use C language only when we need it, in the example of [waveinfo] vs [soundfile_info], both aren't the good way for me, we just need the [binfile] external for reading the header, and all the other stuff can be done into a pd patch. we don't need [binfile]! Pd is proven to be turing complete, so it should be easy enough to write an operating system entirely in Pd (that is: a patch) that will allow you to read/write soundfiles in any desired format. mgdasr IOhannes True, but looking outside of the scope of audio for a second... A student of mine did a project based on microwave background radiation measurements taken from radio telescopes, in order to deal with data that was truly random in some way (I'm skipping a debate about the randomness or otherwise in cosmological terms, the big bang etc.) He accessed binary files to generate points. Admittedly this was in Processing, but the ability to deal with any binary data and decode it on an ad-hoc basis was essential for this project to work. The point I am trying to make is that Pd should be able to read and write any file, with interpretation of the data implemented on an ad-hoc basis. In this way, mrpeach/binfile is incredibly useful. Obviously non-audio files will mostly generate noise if played back as audio, but Pd provides so many other ways in which data can be sonified, visualized etc...

I've made a test patch to demonstrate - highpass filtering on a modulation signal to an [osc~] object. If there was a significant DC offset then the carrier frequency of the [osc~] would be offset slightly as the modulation index is increased.

Something gets corrupted in Pd but I don't know what. the problem is, that on w32 file-handles can be incompatible between different c-runtime versions and each dll uses the c-runtime it has been linked too. this means that file handles opened by one dll (e.g.: Pd-core) might not be closeable by another dll (e.g. Gem). Thanks IOhannes, So there is some sloppiness in Windows, which is hardly a surprise since it's not created with the integrity of a *nix system. Fortunately for me, this piece has to work only on Mac OS X for now - on the percussionist's MacBook. I can use my old laptop to develop the project for now until I fix my new machine's Ubuntu/Pd/Gem issues. It's good to know there is a solution on the way though. Ed on the other side, Pd0.43 would only provide a function to open files (using all those search paths), but none to close them. this means, that whenever a file is opened via the search-path feature (and Gem uses that a lot), it is impossible to close it - effectively leading to a file-handle leak. now with Pd-0.43 there finally is a sys_close() function that allows those file-handles to be closed in the proper context (that is: the pd dll). unfortunately this does not mean that the problem will magically go away by upgrading to Pd-0.43 - the caller (e.g. Gem) has to use the new function in order to have an effect. starting with Gem-0.94, Gem should be able to handle the problem (and even continue to work with older Pd's - at the expense of keeping the file-handle leak with Pd0.43) fgamsdr IOhannes ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] array size (was Re: arraysize)
I think you can't fix a bug in a core object and retain complete backwards compatibility in terms of the audio result of old patches, unless you implement a pre-0.44 mode or something. But why would you want to do that? Perhaps a method can be used to switch between the two modes in hip~, but that might introduce a small overhead. I think the integrity of the objects in terms of what they should do is more important than total backwards compatibilty - old patches will still load, but they may not sound _exactly_ the same. Personally I'd like hip~ to do highpass filtering properly, and so my expectation when I invoke hip~ is that it will do exactly that. Having a patch that works like this but I don't know why is a bad thing. I'd be sure to find the tiny DC component a nuisance at some point. Ed For the hip~ problem, I'm fine with just fixing it in 0.44, leaving it as hip~, and being done with it. I agree with Jonathan: the default behavior should be the non-buggy behavior. The issue I am addressing is the -pre-0.44-hip idea and other ideas for providing backwards compatibility. Namespaces provide a nice, clean technique for doing this, on top of other advantages. And if we implement them right, people will only need to know about them if then need to do advanced things like running a patch in 0.44 while using a 0.42 compatibility mode. Most users are just going to see the [import] or [declare] statement in a patch. I think that's proven to be a much more newbie-friendly way to load external libraries than command line flags, especially on Mac and Windows. Namespaces are part of general programming, and are essential unless you are willing to greatly limit the domain the language is used for. I think we can implement namespaces that are simple and Pdish. I think we're close. Even C requires the use of a crufty form of namespaces. Try writing a C program without a single #include. .hc On 10/02/2012 08:33 PM, Miller Puckette wrote: Right, the two demands I'm trying to reconcile are keeping the name hip~ (so that old patches remain comprehensible) and yet making hip~ work correctly -- it's a bug fix. Seems to me one ought to be able to fix bugs without diving into library version confusion.

One thing libc did not do is break backwards compatibility of functions. I think the libc example is a better approach than the -pre-0.44-hip flag or the aliasing to work around the existing versions of [pow]. My central point is that Pd should have a fully functioning namespace like modern languages do (C++, Obj-C, Java, Python, Ruby, Lua, Haskell, etc. etc.) That's one lesson that we've learned from C. Part of that is having a standard library that can be overridden. Then if people want to have old versions of the standard library, they can easily be accomodated by adding the version number to the name of the library. .hc On 10/02/2012 07:02 PM, Miller Puckette wrote: The libc way is just to have one libc and kludge your way through compatibility problems.

I'm working on a drum machine to be used in a mobile game- it's a trading card game. Right now, I have a 64 step grid with 5 instruments ready (although a tad messy :D) and I can manually write patterns in by hand using toggle boxes. In every turn, the game features many different game states, like deck building, defense, attack and so on. It would be great to have a drum machine that can change beat patterns based on those states, and maybe generate fresh patterns in a controlled way. Two different problems, I know, but I was wondering first of all how you would solve the saving of patterns inside the instrument. I would basically create arrays with patterns in them, name them appropriately and then tell PD when to change to specific patterns via message. Is there a better way I'm missing? The idea is to create a very dynamic drumsound, which is closely related to what's happening on screen. We can already change the tempo and mix sounds in and out, but the real fun starts when patterns will become more flexible! Thanks for reading, any advice is greatly appreciated!

Re: [PD] Video synthesizer emulation
Perhaps a good place to start is to work out what the aliased value of 3.2MHz is - i.e. when you divide 3.2MHz by the number of lines over which the signal is spread (625 for the PAL system).

My starting point is the LZX system, an old school analogue video synth which has been rebuilt today using modern circuitry components. Obviously that wonderful tool is way too expansive for me so I thought I could build something similar using Pd. My first goal is to succesfully emulate the Video Waveform Generator: http://www.youtube.com/watch?v=pbpFgvttBZw Here is a detailed description: http://www.lzxindustries.net/modules/video-waveform-generator I've tried to use [pix_sig2pix~], it works quite nicely and the patterns I get are almost identical to the ones in the video (including all the fm and pwm stuff). The problems are in the second part of the video, when they use high frequencies (~ 3mhz) to generate vertical bands. I'm pretty sure I can't use the same approach with Pd. The other option would be to use GLSL shaders, but it has two major drawbacks: first, it won't be using raw signal but control messages (no sound generation); second, it won't be patchable, once the parameters are converted into an image all the informations about frequencies are lost and I won't be able to use it to modulate another shader. I'd like to know from somebody who has much more experience than me what would be the best approach. Are there any limitations or constraints within the [pix_sig2pix~] object or Pd itself that I should be aware of?

I'm writing an external to be built into an iOS app that's running Pd. The
catch is I need to interface with a C++ library within the external.
The external builds and runs fine if I'm using the C compiler (in Xcode) but I
can't access the C++ library functions. If I switch it to compile in C++ (by
changing the objective-c file from .m to .mm) then I can use the C++ library
functions but it complains that it can't find 'class_addmethod'
'No matching function for call to 'class_addmethod'
I've tried declaring the setup function as C code like Katja explains on her
site:
extern C void external_tilde_setup(void) { }
But that still didn't seem to work. I was also going through the list and
found this thread but I'm not sure if it's the right approach. Plus I'm more
of an audio guy than programmer :)

Re: [PD] [Pd] Compile external with C++ compiler?
It's really easy actually.
You make the object in C, compile it and then build your patch in pd vanilla +
the object.
Then in the xcode object you just call the setup function for the object, the
source code for which gets included in the xcode project.
That's all I know. I'm not responsible for the Xcode/C++ of this app, only the
Pd patch and Pd objects, so there may be more to it. It's quite simple though,
my developer colleague tells me.
Don't forget, C is a subset of C++!

Hi Charles,
Thanks for replying!
I don't believe it's a problem calling C functions, you just have to declare
them with 'extern C' to avoid name mangling (I think??).
The issue is, when I want to use C++ I have to switch the implementation file
to .mm, which is a Objective-C++ file. As soon as I do this Xcode starts
complaining about 'class_addmethod()' in my setup function. The weird thing is
that it only applies to 'class_addmethod()'. For example, 'class_addbang()',
'class_new()' all work fine.
It seems like it's an issue only with this function, and it looks like
class_addMethod is already a function used by Objective-C I think maybe
there's some namespace issues, but I have no idea how to resolve this.
wrote wrapper functions to export a C-callable public interface to C++
functions.
Yep, this is what I'm doing now. A bit annoying because I was so close :)
Thanks for your help!

Joe: I've built externals that just call C++ functions that I declared
with extern C or wrote wrapper functions to export a C-callable
public interface to C++ functions. Best suggestion I've got is to
identify which functions you've got are going to be public and which
ones are private and plan out how you're going to declare them.
