Re: [PD] PD on Raspbian
Hi, I have never managed to get pd-extended to work properly on Raspbian. The vanilla version available from the repos works better. You can then install external libs if you need them. Cheers, Pierre. 2014-03-19 13:29 GMT+01:00 Christian Fischer m...@c-m-fischer.de: Hi everyone, two (beginner) questions regarding Pd-extended 0.43.3 on Rpi Raspbian Wheezy: - There is an I/O error message in the Pd window as there is only an audio out (but no in) on the Rpi. Just deactivating the inlet in Pd audio settings doesn't help. ALSA is used by default. What can be done to avoid error message? However sound out works fine. - When opening a new Pd window (ctrl+n), it pops up so high in the bottom left corner of the screen, that you can not see the menu anymore. Therefore the window is not moveable or usable. Used Pd already on various PCs and OS but this I have never experienced. What can be done?

There's definitely a lot of quirkiness to getting it running... for example ALSA gets in an infinite restart loop when attempting low latency on pd-extended, but vanilla starts up fine under the same settings. And then there's the fact that an issue in the kernel screws up USB audio on major distros like Raspbian. I'm using the Satellite CCRMA distro right now with much better success. So far I've got various delays, a looper, and a waveshaper distortion running within the same patch, at 20ms latency with very few noticeable dropouts. Parameters are adjustable with a QuNeo MIDI controller and with a button attached to the GPIO pins. The Pi is a bit more affordable than the UDOO boards, but then again I had to buy a powered USB hub. Ultimately for one audio input the Raspberry Pi could probably serve most purposes, while the UDOO is more likely to scale to bigger installations. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- --- Ritsch, Winfried, Ao.Univ.Prof. Dipl.-Ing.

[PD] Data structures and click event
Dear list, First of all i'd like to say that i'm very impressed by the potential of data structures in Pd. I've always kind of ignored this feature and it's a pity because it's really worth diving into it. That being said I think that help and example patches are far from sufficient for beginners, and if it wasn't for Chris McCormick's s-abstractions I would have been able to really figure out how to use them (stuff like how to make an entire polygon draggable, how to use GOP with proper scaling, etc.). I m now stuck with a question. How can I identify the element which was just clicked ? I know that [struc] outputs the events, like click, selection and change, but I thought I could identify individual elements by their pointer id. It turns out that I get the same pointer for every element, although I created them sequentially (using [append]). (I guess something must be escaping me about pointers... I've noticed that within the same template, I get different pointers for elements on different y-levels, but the same pointer for all the element on the same y-level regardless of their x.)

Don't know if it's the same issue which you're experiencing. Anyway, it seems that this was about jackd2 writing config files to different places, which can be out of sync under certain conditions. Not sure if this is a correct description but it is my interpretation. Looking at running processes in command htop, I always noticed a jackdbus processing still running when the dbus error was given. Killing the jackdbus process sometimes helped. But in the course of time I've somehow learned how to avoid it at all, by carefully considering the right order of operations when starting processes. I have PulseAudio disabled by default, so I can start Jack first, then the Jack clients, of which PulseAudio may be one. Then eventually the PulseAudio clients. When killing processes, everything in reverse order. I don't like this hocus pocus, but well, I'm happy if it works at all. On Kubuntu I couldn't get PulseAudio to cooperate with Jack.

Re: [PD] Pd as sound editor (issue with scrolling a table) ??
Wow, your patch is impressive, i'd missed that. I've looked at maelstrom's editor as well. Both will be nice things to study. i think i'll stick to data structures though because what i need is something to record and edit discrete events, not an audio signal. I don't think i have to use tables at all finally. 2014-03-04 12:12 GMT+01:00 i go bananas hard@gmail.com: just for interest perhaps, here's the sound editor i made years ago: http://puredata.hurleur.com/sujet-1295-sound-editor and probably even more interesting, here is maelstorm's wave display abstraction: http://puredata.hurleur.com/sujet-5890-waveform-display basically, what maelstorm discovered was that using [until] with a counter was not nearly fast enough to do the calculations needed for a decent zoom/scroll function, and we looked into it, and there just didn't seem to be a vanilla workaround. So he uses iem_tab objects to do the table calculations.

[PD] Bugs in Pd-Extended in Ubuntu LTS
Dear list, I've been using Pd-extended in Ubuntu LTS (12.04) a lot lately, and a couple of bugs are beginning to get on my nerves... first it randomly crashes and also crashes X (i get a black screen, and after a few seconds i'm prompted for my password to log into my session again), whenever I'm typing something in an object box (i haven't been able to figure out exaclty what character was causing this, it really looks random to me). I also get constant error messages in the console when using JACK (JACKerror: Cannot use real-time scheduling (RR/55)(1: Operation not permitted) JACKerror: JackClient::AcquireSelfRealTime error). The sound works sometimes though, but Pd also freezes every once in a while. I also get error messages with Alsa. I have installed Pd-extended from the Ubuntu repos. It seems to be the same version as the one available on puredata.info (0.43.4). I don't know what to do.

Re: [PD] Bugs in Pd-Extended in Ubuntu LTS
Hi all, Thanks for your replies. I get the same error message in the console about JACK, regardless of whether I start it before Pd or not. The sound works though most of the time. There is a package in the Ubuntu repos for pd-extended. It's called Pure Data with patches and a large collection of externals in the Ubuntu software Center. My Ubuntu is up to date (last update last week-end I believe). Could it be that it was fixed in 13.04 but not in the older LTS version ?

Re: [PD] audio output AND input with the Rpi?

It's fully functional as far as i can tell (it works in duplex at 44100 Hz with one input) and has been since the beginning on the RPi without any slowing down of the USB speed. I can even prove it with a video (http://www.youtube.com/watch?v=NwJNeouLqgQ) ! Problem is, i don't know how to edit the page...

Pd (gui) audio preferences allows selection of the interface for both input and output. Output only is lovely and clean but as soon as the device is selected for audio input the audio quality drops horrendously (vaguely recognisable from the original signal).. ..although what gives me hope is I CAN software monitor the input (poorly) in 'Test Audio and MIDI' with this arrangement. ..with Behringer UCA202 (at 48000khz): Output only in Pd is poor (beating and popping sound - possibly sounds like a samp rate conversion issue). When device is selected as Pd input software monitoring is possible and oddly, though the result is still poor, there is effectively no drop in quality from having the device selected only for output and the monitored signal sounds drastically better than at 44100khz. ..with Turtle Beach Amigo II* (at 44100): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and only the output is selected in Pd it works but with a lot of jitter. Selecting the device for input too causes a further drop in audio quality although again I can software monitor the input in 'Test Audio and MIDI' If plugged in after boot the OS crashes. The Satellite CCRMA (operating via ssh) and Pd-extended: ..with Behringer UCA202 (at 44100 and 48000): Alsamixer picks the device up but again the input section shows nothing. If I have the device plugged in from boot then I get the same behaviour with it as I do in Pd vanilla on the Pd-LA Raspian image, ie. software input monitoring but at an extremely poor quality. If I don't plug the device in from boot I see it in Pd audio prefs but get this: ALSA input error (snd_pcm_open): No such

I thought it was impossible (i'd never even tried, to be honest). So here's my (probably stupid) question : is this a feature ? Yes, it works fine due to the topological sort of the DSP graph into a DSP chain - but DSP is block-based, so be aware that each block is read as a whole before it is written - this probably only matters if you wanted to write to a different location for non-block-sized feedback effects. Also you might have little glitchy issues when table length isn't an exact multiple of the block size. There are some examples of [tabreceive~]--stuff--[tabsend~] in the docs, probably in the FFT section of the manual. A simple looper might be a [tabplay~]--stuff--[tabwrite~] thing with the tabplay~ and tabwrite~ both triggered from the same source, and retriggerd by the tabplay~ done bang...

[PD] How to make a looper ?
Dear list, i've been working on a simple looper (the sound on sound thing, Eno Fripp, Eno all by himself, you know what I mean). I decided to use two tables, write to T1 while reading T2, and write to T2 while reading T1, adding the input and the currently playing table together before writing. I'm faced with two issues. One is a click I hear everytime I record a new piece of sound (I m almost certain it happens while switching from one table to the other), and another is final volume. What is the proper way of reading two tables continuously and alternatively ? And conversely, what is the proper way of writing continuously to two tables alternatively ? I'm currently using threshold~. About the final volume, the problem is that the first sound i record gets burried in the later recordings, and it all ends up distorting because it too loud in the end. I suppose I should use a limiter on the input, and maybe compress the output. Is that correct ? Can someone point me to a good compressor/limiter in Pd ? Or maybe there's a much better way to make a looper in Pd... Cheers, Pierre. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

So based on it i've made a very crude [shell]-based omxplayer controller in Pd, see attached. As omxplayer can be controlled via keystrokes, you can expand this patch's possibilities very easily. For now, you can choose a file, play it, pause and resume, restart the video, quit omxplayer, increase and decrease volume. I encounter an annoying bug when restarting a video : one can briefly see what's behind the window, be it a console or lxde's desktop. Happily, omxplayer has also a counter-bug thats prevents the desktop to refresh itself (it stays black : you have to move the mouse all over the screen to refresh). So to keep the restart prettier, you have to launch the desktop manager. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] IR reverb and partconv~
Hello, While readin Katja's website i discovered the [partconv~] object from Ben Saylor's library. I had actually used it long time ago with some IR reverbs, but I then judged the latency to big to be usable live. I gave it another shot this morning, and realized that the partition size could be set in [partconv~]. A lower partition size reduced the latency to something usable, which is cool, but it also cuts the tail of the reverb (it sounds very unnatural will low partition sizes). Could somebody please explain to me whether it is possible to fix this behaviour ?

Re: [PD] Message from the boss of Raspberry Pi Foundation !
Hi, Ok, so Charles Henry has been working on this, good. Anybody else would have something to propose ? I'd love to help but my technical background is far from sufficient. Bringing this to the attention of the RPi foundation is about all I could do I think. @Hardoff : the patch i'm using in the video requires 16 ms of latency, because it uses phase vocoding. You can drop to 10 ms without it, and I guess even lower would be possible. I use the very first version of the Pi, with half the RAM the new model has. If we can get the GPU to compute the audio i hope that we'll be able to get to really reasonable latencies (to me 6 to 8 ms is really enough to play live). Also, i use the regular Pd fro the debian repos. I can't tell you whether Miller's or Katja's version work better. Cheers, Piere. 2013/2/8 Simon Iten itensi...@gmail.com pierre wrote in his blog that he can go as low as 10ms, later in the settings he writes about 16ms.

[PD] Raspberry Pi : DSP on the GPU ? (WAS : Message from the boss of Raspberry Pi Foundation !)
Hi again Katja, I just read through it. Couldn't find anything about having the GPU process some audio. It's really mostly about why it's a bad (or good) thing to keep the GPU closed-source (at least that's what I understand [?]). So I guess there isn't must we can do on our own to access the GPU. But then, what can Eben and his team do about it ? I'd like to know what answer we can give him. If he says just waiting for an application like this I am assuming that it must have aroused his interest somehow. And I believe that it would be great if people in the Pd community got involved. All I can provide is some testing, but others could contribute more (if i'm not mistaken, Miller Puckette did a great job fixing the analog out for instance). I think we should try and play a part in the development of the Pi. And if we're lucky we'll finally have that Pd box people have been dreaming about for years.

Because of the patches I'm wanting to run I do need to have the gui so am wondering if anyone has some tips to squeeze a little more out the pi? Have updated Raspbian to most recent, done the usb tweak to 1.1, removed pulseaudio. I'm running the pi via ssh through my laptop. I'm also running vncserver on the pi and xvncviewer on my debian lappy. Also have an imic, so don't need anything other than usb-audio. So things like: is it worth disabling some of the audio and midi modules, that kind of stuff, well you know, anything really?

[PD] Pd launched via rc.local can't search path
Hi, I'm trying to get Pd to run at startup. I've put the command in /etc/rc.local. Everything works fine, except that Pd seems to be unable to search the paths I specified (either in .pdsettings or directly in the command line). I'm trying to use a patch with the reverb described in the audio examples (G.08 I think), and there's an abstraction in it which lives in 3.audio.examples. Every time I boot Pd starts all right, but I get errors because it can't create the abstraction. It's a bit weird because the very same command works like a charm once i've logged in. Any clue ?

Re: [PD] Raspberry Pi does denormals
Hi Katja, I tried on my laptop (Intel dual-core 2 duo, 1,66GHz), and it works fine I guess. It takes a little to go from 0 to 1 and back, but there doesn't seem to be any particular issues with NAN and INF numbers. Now on the Pi : sending a NAN to the lop~ makes it hang. Sending 1 works fine, but sending 0 after that results in a different behaviour compared to that of my laptop : the number of non-zero digits seems to grow much faster, and it never really actually goes to 0. It (apparently) hangs with still about 30 non-zero digits to the right of the very long number. I guess you're not the only one, are you ? Cheers, Pierre. 2013/1/22 katja katjavet...@gmail.com Hey Pierre, I've commented patch denorm-test.pd in such a way that it explains the topic a bit more (see attached). Now I'd like to ask you, if you can run the patch on a 'normal' computer and on your Raspberry Pi for comparison. If you have Pd gui on the Pi, you should be able to check if your Pd install has a denormals issue. It's hard to believe that I would be the only one experiencing this issue, but I need to be sure. In my previous mail I stated that it is easy to avoid subnormals by just feeding a very small number in objects that may decay into subnormal range (feedback delay lines and most filters). But in practice, this is not always so easy, as I am now experiencing while trying to make a big patch work well on the Pi. There are many more filters than I was aware of. For example, following a bit-mangling operation a [hip~] was added to remove DC. Now if the bit-mangler stops receiving signal input, [hip~] starts to chew subnormals until it will receive signal again. I found that each filter struggling with subnormals eats at least 6% CPU time (while they do some 0.25% in normal state). Pd objects should really take care of this in one way or another, it's too confusing for the user to sort it out. I'm going to try recompile Pd with PD_BIGORSMALL checks enabled, and see what it means for the normal performance of the filter objects.

Every time you post something here I feel like some messages from a technical NASA mailing list are being accidentally sent to pd-list! Cheers, Pierre. 2013/1/21 katja katjavet...@gmail.com Pierre, the way how denormals can impact performance on the Pi, is whenever a an object with feedback delay (IIR filter, reverb etc.) stops receiving input signal, it's values decay into the subnormal range, which causes substantial increase of CPU load. Such situations can be avoided by adding a tiny DC value to the object input, like [+~ 1e-21] (note the minus sign in the number notation). When a normal audio signal is present, that number is too small to be added (because of limited precision), but when audio stops, it prevents subnormals. Another thing is, one should be careful not to accidentally send 'inf' or 'nan' into such objects, as they can not recover from it. This would be particularly annoying in a public performance, since you'd need to reload the containing patch to recover. It is possible to prevent denormals via C code, as it is currently done for Pd on Intel processors, but this implements a lot of conditional checks and it means performance loss for many objects. For current Intel computers the extra load is not so much of a problem, but for poor Raspberry Pi one would rather like to save a few instructions, instead of adding more.

Re: [PD] Raspberry Pi versus BeagleBoard ?
Hi Miller, Thank you for your reply. I didn't know there could be such a difference in performance between two ARM chips. It seems very attractive indeed, and i think i'll contact the people at CCRMA to ask about the latency they achieved. If it's low enough i'll definitely give it a try. Cheers, Pierre. 2012/12/17 Miller Puckette m...@ucsd.edu I could be wrong, but I believe the Beagleboard is ARMv7 and the Pi is ARM v6 - so BB could easily have twice the floating-point erformance of Pi.

Hi, I wrote an e-mail to the guys who made the Satellite CCRMA image for the BB, asking about latency and quality of the built-in audio interface. I didn't get a reply to any of these questions, so I guess i'll have to buy one and figure out myself. One interesting news though is that they are preparing an image for the Raspberry Pi.

Hm, ok. So if it's the satellite distro then Pd should run in rt with JACK, which means that the latency you mention is fairly close to the minimum one can get. Am I wrong ?

Re: [PD] pd-extended 0.43.3/ raspberry pi (wheezy) - start patch on boot?
Hi Epic, I got Pd running at startup on the RPi without modifying /etc/init.d/pd-extended. All I did is add a line in /etc/rc.local, something like 'pd -nogui -audiobuf 100 -noadc /home/pi/mypatch.pd' This will start Pd, without GUI, with a buffer big enough for the RPi, without audio in (there's no capture on the RPi), and open the patch called 'mypatch.pd' in the home folder. This should work a fresh Raspbian install. Pd will start without the user having to login, nor start X. There's also an alternate solution involving the cration of a bash script. I described it here on my blog : http://guitarextended.wordpress.com/2012/08/28/running-pd-on-a-headless-raspberry-pi/ Cheers, Pierre.

Cheers, Pierre. 2012/10/5 Hans-Christoph Steiner h...@at.or.at I think there is mp3write~ in 'unauthorized' lib but I've never used it. There is the pdogg lib, which has oggwrite~. .hc On 10/05/2012 06:55 AM, Pierre Massat wrote: Dear List, How would you go about recording the audio output of a Pd patch directly to mp3 (or any other compressed format actually), without using the object from the Unauthorized library ?

[PD] Get metadata with readanysf~ ?
Dear list, Any idea whether it's possible to get the metadata off a stream playing in readanysf~? It seems like webradio streams only broadcast metadata at regular intervals an not continuously, so i would expect the solution to be non-trivial.

Re: [PD] Satchmo Awards (small-scale Pd+RPi SuitSup equipment awards)
Excuse me, what is Miller's RPi system image again ? I must have missed something. Cheers, Pierre. 2012/10/11 Joe Deken newblank...@newblankets.org The first Satch-Suitsup Awards (4 X Raspberry Pi kits with Miller's RPi system image as a starting point) have been sent out on their merry way, and the first four teams are busily out there now doing their individual/connected things: 01: Gi Vania and SIU team 02: Theron Trowbridge and CrashSpace LA team 03: Phil Stone (UC Davis) 04: Rick Wagner and SDSC (San Diego Supercomputer Center) team (Of course the Satchmo Awards include an original honorary Satchmo 00 that went to Miller ... but msp has an extremely large team, and a pretty full schedule of other interests, so he gets his own list.) == NOMINATIONS/APPLICATIONS STILL WELCOME New Blankets is still keen to make a few additional Satchmo Awards to additional interested/qualified Pd folks. NB would particularly like to include some RPi SuitSup hackers who are associated with patching circles -- and in that regard it would be great to have some SuitSup patching-circle activity in other countries outside the U.S. where Pd activity is flourishing. There is now also a rudimentary mailing list for questions, (and for sharing SuitSup Pd patches, tips and SuitSup hardware tricks) available at: suit...@newblankets.org === ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Pdsend on Raspbian...
Thanks for your help, it worked. I hadn't actually installed Pd. I used apt-get install pd (it only installed puredata-core), instead of apt-get install puredata.
