how do I edit puredata.info ?
by Mathieu Bouchard 30 Jul '10

30 Jul '10

how do I edit this page ? http://puredata.info/downloads/other_members/ I can't see how to add any entries, now how to edit the «GridFlow» entry. Clicking «Modify» only seems to be about the text at the top of the bullet-list. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

Pd-vanilla 0.42-5 on Maemo N900
by Koray Tahiroglu 30 Jul '10

30 Jul '10

We, together with Jari Kleimola, compiled Pd-vanilla 0.42-5 successfully on Maemo 5 in N900. After a major Maemo 5 update, it was pretty much straightforward with libasound2 Alsa support and minor changes when it complains touch and tk related things in makefile. However, Alsa in N900 is a plug-in and DSP can be blocked as it can be in use by some other tasks. So, even with 22050 sample rate and 100-500ms buffer, we get huge audio cuts. Currently we are planning to implement an Alsa backend for Pd usage in N900. Seems like making Jack work might take more time/effort. Does anyone have suggestions/ideas/implementations on Alsa backend ? It is a native Pd-vanilla, not PDa or any other token, so you can make your pd files work on N900 directly without any need for a specific platform. I will post a link later when we document the necessary things.

iemguts, [#many]
by Mathieu Bouchard 30 Jul '10

30 Jul '10

In the end, GridFlow will not depend on anything in iemguts, because iemguts is being removed from pd-extended. Too bad for the case where anyone loads [iemguts/propertybang] after [gf/propertybang] : [#many]'s properties dialogue will not open after that. Oh yeah, two new things in 9.10 : [#many] has a properties dialogue abstraction called [#many-prop], and it's made with [gf/propertybang], which is also new. Well, there are more new things than just that. btw, [#many] is going to change soon in an incompatible way : arguments $4 and $5 are going to disappear and be replaced by something else more convenient and automatic. I suppose that this will be the last incompatible change for [#many]. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

Line comportments.
by Olivier Baudu 29 Jul '10

29 Jul '10

Hi, I noticed different strange comportments with [line]. 1) When I send, for exemple, [100 10000( to a [line] for the second time the line give me 100 during 10 sec. I expected it no to give me anything as it is said in the help-file : "You should also note that if you click that [bng] again a second time, nothing happens. This is because [line] is already at 1000, so sending it new instructions to ramp to 1000 is meaningless and has no effect." 2) When I send [stop( to the line I can get the last send value in the [number \ I've put under. OK. But this last value is not use as the new beginning of the next ramp. It's the last ramp's beginning that is. Whereas if I send new taget and time during the ramp it's the current value which is use as the beginning value for the ramp. 3) I tried to put a [sel ] under the [line ] (with sure sent value by the line) to reset the line, or to stop the ramp. But the result is different if the bang is send from the [sel] than if I click it manually. --> If I bang manually [stop( the ramp stop, an I get the last value. --> If the [sel ] bang [stop( the ramp stop but send me the last beginning value. I try to put a [i]--[change] under the line expecting to solve the 1) problem... but it doesn't work. Is it the same for everyone ? I use 0.42.5-extended-rc5 on Ubuntu Lucid. Thank you. 01ivier.

pd on armv7 (beagleboard): crackles [SOLVED]
by Damian Stewart 29 Jul '10

29 Jul '10

hi all, i fixed my issues with Pd on my Beagleboard running Ubuntu. the solution (thanks to Julian Oliver's help) was to load the oss module (sudo modprobe snd-pcm-oss) then run pd using the oss driver (pd -oss), and it sounds just lovely. thanks for the other help nonetheless! cheers, damian -- damian stewart . @damiannz . damian(a)frey.co.nz frey . contemporary art . http://www.frey.co.nz

new readanysf~ for mac intel
by august 29 Jul '10

29 Jul '10

Hi, So, after squashing bugs, making updates, and compiling on the ever-so-handy pd farm, there is now a new readanysf~ binary for mac intel machines. I don't own or use a mac, so I can only build it blindly without testing. please download and test. http://aug.ment.org/software/readanysf~0.40_MacOSX-Intel.tar.gz This should solve the dangling file handle problem and a few others. Unfortunately, I was unable to package the lastest gavl that would solve the wav file problems that Derek posted. -august.

Auto unique number tagging of gui objects
by saint 29 Jul '10

29 Jul '10

Hi, Is there a way to scan a patch (and then it's child subpatches and theirs etc. etc.) and assign a unique consecutive number to each graphical object? For example say I have 4 sliders in a patch I want to number them so that the labels now read say 001, 002, 003 and 004 and they now respond to messages sent to r-001, r-002,..etc. and they are now sending information on s-001, s-002,..etc. And also this patch calls upon an abstraction that has 3 toggles and I want them to be labelled, sending and receiving through 005, 006 and 007 etc. etc. I want to know if I can automate this task so that I can apply it to patches I've already made. I know I am probably re-inventing the wheel here but I want to do this in vanilla hopefully. My goal is for any gui parameter to be able to modulate any other parameter (as long as they are of the same type) simply by typing two numbers into number boxes that will link them. A simple modulation matrix of sorts. Cheers as always, John.
