[PD] ubuntu portaudio unstable audio device list
Hello list, I have trouble with automatically choosing audio devices because the list of available device is not the same each time I launch pd. I am on ubuntu 12.04 / pd 0.44.3. I want to use portaudio with the pulse device because I'm running another software in parallel, that can only use pulse for playing sound. When I launch pd, the list of available device for portaudio is not the same each time... that makes difficult to choose pulse automatically. Is there anything I can do to be sure of choosing the good device?

[PD] Small work offer: Help to compile an external in windows
To whoever might interest, I wanted to compile Chikashi Myiama's leapmotion external for Pd in windows, using T Grill's Flext architecture. As I'm not a programmer, it isn't practical to learn how to prepare the building environment on my own; I also would doubt that anyone will do this work on its own in the near future, I would be interested to know if anyone with windows building skills would be interested in teaching me how to prepare my system to build this (and other?) externals. I'm doing this proposal on my own, without the support of any institution behind me. Being sure that I can't offer a full programmer's salary, anyway I would be interested to know if anyone out there is interested in making me an offer. Can you send your replies directly to my mail?

Re: [PD] direct connection from pd to webrowser, low latency
onyx, I would also check out the latency in the browser audio player. I somehow suspect that is where you are acquiring the largest portion of buffers and latency. I'm unsure, however, if you can even access and set the incoming buffer there. If not, you might have to write your own audio player...which would defeat your purpose of using the browser in a cell phone. Flash does let you set the incoming audio buffer, ...but alas, many phones can't run flash. WebRTC might be the best option on the browser side. keep us posted! suerte -august. the audio side was just standard wireless hifi headphones, using lots of headphones but only two of the transmitters.

Re: [PD] Sensors GPIO Raspberry Pi Pd
Here's a patch to display data from two D6T sensors on the same I2C bus. The clock line is switched using a 4051 analog multiplexer. The control line is GPIO_17 of the Pi connected to A of the 4051 (B, C and Inhibit are at 0V). 10k resistors to 3.3V are on each sensor's clock line at X0 and X1 of the 4051 (I2C clock connects to X). Because the code accesses the GPIO file system it needs to be run as root. I have two different sensors so the code reads two different packet lengths. Just a proof of concept, there could be up to 8 identical sensors on the same bus with this setup.

And also are you attaching the MC14051 to any type of board/adaptor or just soldering straight on to the pins? I have it in a breadboard right now, to make it more permanent I would solder a socket to a prototyping board then (after verifying the connections) plug the chip into the socket. Soldering to the pins makes it difficult to replace the IC, and risks damaging it with the heat if you're not good at soldering quickly and to the point. A CD4051 would also work, it's basically the same circuit.

[PD] Resize GUI objects in GOP ?
Hi, To make patches for friends or to show them to newbies, I need present things very clearly, and bigger. So I need to increase sizes of the font and GUIS. The standard font properties (Ctl+T) is quite nice, but boxes are sometimes stack on others. The main issue is to resize GUI objects placed in abstractions. I saw the [universal] object which could be use to resize GUIS. Use it with the [donecanviasdialog message, it could be okay. But is there someone who think about a simplier solution, with the iemguts lib for instance ?

Re: [PD] Resize GUI objects in GOP ?
Not sure if you are referring to iemgui objects. If so, check out pd-l2ork which has bevels that allow easy resizing of gui objects and repositioning of its labels, including resizing and moving the gop area itself. The latest version (to be uploaded shortly) also has a comprehensive checking for all labels and comments to see if they fit the gop window, including dynamic changes to their properties. Pd-L2Ork also auto-adjusts fonts in objects like numbox2 when they are resized so that you don't have to guess the font size that best fits that specific size.

[PD] got jump-on-click arrays working
Hi list, * I got jump-on-click arrays working. Basically you can click anywhere in the graph and the array element in that vertical column will jump to your mouse position. * Implemented bargraph style for Put menu arrays. (See attached) This is basically a multi-slider. Questions: * using bit masks, exactly how many flags can I scrunch into a floatarg? Arrays use one floatarg in a pd file to keep 1) the saveit flag (i.e., whether or not data is saved with the patch), and 2) plot style, to which I've added one more. I'd like to add a flag for jump-on-click, and if possible one for x/y ticks. * can I add a A_DEFFLOAT for plot color for arrays? * for bar graph arrays, should the user be able to specify inner/outer color for the bar, or is inner color with black outline good enough? * for arrays with a small number of elements that aren't jump on click the UX is misleading: with points-style arrays you can only click on a small undifferentiated part of the line. Should I change this so that the hot spot is the entire line?

Yes, you're right, those new functionnalities are great, thanks to developers. But I think it is useful to have a paper document to see quickly some objects organized and to print.

Re: [PD] got jump-on-click arrays working
Oh, this is great news! Can´t give you any response on the two first questions but here is a fast response to the other two...

Basically you can click anywhere in the graph and the array element in that vertical column will jump to your mouse position. * Implemented bargraph style for Put menu arrays. (See attached) This is basically a multi-slider. Questions: * using bit masks, exactly how many flags can I scrunch into a floatarg? Arrays use one floatarg in a pd file to keep 1) the saveit flag (i.e., whether or not data is saved with the patch), and 2) plot style, to which I've added one more. I'd like to add a flag for jump-on-click, and if possible one for x/y ticks. * can I add a A_DEFFLOAT for plot color for arrays? * for bar graph arrays, should the user be able to specify inner/outer color for the bar, or is inner color with black outline good enough? I think the ability to change both inner and outer color for the bar should be preferred. * for arrays with a small number of elements that aren't jump on click the UX is misleading: with points-style arrays you can only click on a small undifferentiated part of the line. Should I change this so that the hot spot is the entire line? I think, yes! Can´t really see situations where a fraction of the line as hot spot should be preferred...

I'm guessing no since you can already just make a bunch of vsliders in a row, although creating an array is much quicker. :) -Jonathan also having this as an activable option would be nice.. just my 0.02£ y -- http://yvanvolochine.com http://soundcloud.com/yvanvolochine http://vimeo.com/yv ___ 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] Sensors GPIO Raspberry Pi Pd
Hi Martin / all, Possibly overly-nerdy question here: I'm buying the various bits and pieces we require for the multiplexer and I'm noticing quite a difference in pricing options for the pull-up resistors. There's this one: http://uk.farnell.com/welwyn/rc55-10k-0-1/resistor-10k-250mw-0-1/dp/9499938 which is 86p each. Or there's something like this: http://uk.farnell.com/multicomp/mcf-0-25w-10k/resistor-10k-250mw-5/dp/9339060 which is 2p each. The former's spec sheet talks about its very low noise ratio and thinking on from reading the sensors spec sheet it's also pushed there to use low-noise components. Do you think it actually makes any difference? I have to buy a minimum 50 of the cheap ones so buying a couple of the dearer ones doesn't actually make much of a difference. It got me thinking as you mentioned that your getting virtually no PEC errors from the sensors whereas as we are getting them very regularly. I had been thinking it was the soldering of those pernickety sensors but could it also be the cheap 4k resistors currently on our board?

Re: [PD] Sensors GPIO Raspberry Pi Pd
Ordinary 5% resistors will work fine. Probably anything from 1k to 100k would work. Most likely you have a loose connection somewhere. Did you try running the bus at a lower speed? If your wiring is long ( 10cm) it may be better to run it slower.
