get block-size in upsampled / downsampled patches - sample based delay?
by Martin Schied 20 Apr '09

20 Apr '09

Hi, I'm currently creating some analysis patches which have to run upsampled (simply because I don't want to wait ages). Inside these patches I need to know how many samples have been passed (or how much "upsampled time" has passed). So I can't use [delay] and made a counter which counts samples, based on current blocksize and bang~. I get the current blocksize from [bang~] [timer] and [samplerate]. (see attachment) But in upsampled patches the [samplerate~] outputs the "upsampled" samplerate, so my calculated blocksize is upsampling-factor * audio-samplerate. is there a way to get the "upsampling factor"? or is there already a blocksize based [delay] for messages i have overseen? attached the abstraction I use for block size at the moment. cheers ; artin

Hi.. is it possible to configure my PD installation to don't quit immediately when I (stupid as I am) press ctrl+q or command+q(mac)? :) tx. -- http://www.padovani.googlepages.com

Animating with arrays...
by Simon Ball 20 Apr '09

20 Apr '09

Hi list I'm trying to understand how tables/arrays work with animations. As far as I can see, I can place a set of coordinates in text file and then use an array to apply this to elements in a scene. I have been looking at various examples, notably [splinepath], which uses [line] to govern the length and speed of the movement. However, I'm struggling to understand the exact relationship between the co-ordinates written in the text file and what actually happens to an image when rendered. Sometimes I change the numbers and the animation stays the same, other times it appears erratic. I'm trying to trigger animations so that they float and rotate into place. If anyone has any ideas on the best way to approach this, or can direct me to some useful help files, I would really appreciate it. I was looking at a pdf that was packaged with PD-extended called 'GemPrimer'. The documentation was clear and insightful for someone of my level (beginner!) and hoping there might more files like this one... Mac OSX Intel Core Duo 10.4.11. PD-Extended 0.40.3. Thanks Simon

My first external: [fsm] finite state machine for pd
by lsw 19 Apr '09

19 Apr '09

Dear list, i have been absent from pd-list for a few years, but i'd like to change that. :) During the last days i wrote my first external: fsm - finite state machine for pd I wrote this with algorithmic sequencing and sequence recognition in mind. You can find builds for win32, osx and linx, as well as the sources and help-patch with examples at http://floppy35.de/pd/ I didn't test the windows and linux builds (but osx-version seems to work fine), so please tell me, if it works or if it destroys your machine and deletes your mp3-collection. ;) Unfortunately i saw a bit late that moocow had a similar idea earlier... however, my external seems to be a bit different (low-level approach), so it might be still useful for some of you. It's written in plain C and consists of one single c-file, so it should be easy to port and compile for different platforms. Feedback is appreciated. All the best, lsw~

TUIO iPhone web app and web server
by Andrew Turley 18 Apr '09

18 Apr '09

I put together a little iPhone web app and a Python web server that let you send TUIO messages using Safari. The web app sends multitouch information to the web server, which takes care of translating them into TUIO messages. I thought maybe some people on this list might be interested in it. Here's a blog post that talks a little bit about my motivations: http://www.pillowsopher.com/blog/?p=79 And here's a link to the code: http://www.pillowsopher.com/stuff/tuiotouch.tgz andy

Need help for presenting workshop
by Adityo Pratomo 17 Apr '09

17 Apr '09

Hi there everybody, My friend just told me to give a workshop about Pd here in Indonesia. Can anybody suggests what kind of material I should present? Initially I want to give 2 sessions in2 meetings, the first meeting will discuss the basic of Pd, while giving a hands-on practice on making some simple instruments, while on the second meeting I will discuss the visual side of Pd, such as GEM, pdp and pidip. But, can anybody give more suggestion about what to present? I suspect that this kind of workshop is the first in Indonesia, so I just want to give everybody a good impression on this powerful software. Thank you very much -- mataharipertama.wordpress.com kotakmakan.multiply.com

Re: [PD] can't setup midi device - maybe alsa is missing.
by Ed Kelly 17 Apr '09

17 Apr '09

Have a look at what ls /dev/midi* gives you. You may have to link the midi device to one that PD can recognise. I have to do this every time, before I start PD: sudo ln -s /dev/midi1 /dev/midi -e Lone Shark: Synchromatic: Out December 1st 2008 http://www.pyramidtransmissions.com/store Also available through the iTunes store --- On Fri, 17/4/09, IOhannes m zmoelnig <zmoelnig(a)iem.at> wrote: > From: IOhannes m zmoelnig <zmoelnig(a)iem.at> > Subject: Re: [PD] can't setup midi device - maybe alsa is missing. > To: "hard off" <hard.off(a)gmail.com> > Cc: "pd list" <pd-list(a)iem.at> > Date: Friday, 17 April, 2009, 11:43 AM > hard off wrote: > > i just installed pd-0.42-4, but i can't get midi > working. pd -listdev says > > i have no midi devices. > > > > The alsa Aconnectgui interface doesn't list pd as a > midi device either, so > > my guess is that i missed something while installing. > > start pd with "-alsamidi" (or select alsa-midi from the > media-settings) > by default, Pd uses OSS midi, that's why you won't see it > at aconnectgui. > > > fgmar > IOhannes > > _______________________________________________ > Pd-list(a)iem.at > mailing list > UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list >

can't setup midi device - maybe alsa is missing.
by hard off 17 Apr '09

17 Apr '09

i just installed pd-0.42-4, but i can't get midi working. pd -listdev says i have no midi devices. The alsa Aconnectgui interface doesn't list pd as a midi device either, so my guess is that i missed something while installing. the install.txt file says to add this flag: --enable-alsa so, i assume that means i just type in: ./configure --enable-alsa ?? the midi device i am using is an edirol UM-1A and i works fine with pd-extended 0.40
