[PD-announce] xxxxx_workshop_44 Berlin: PD sensor input part II
by Derek Holzer 22 Apr '08

22 Apr '08

April 26th 2PM: AVR/HID Sensor Input into Pure Data with Derek Holzer & Martin Howse We will continue last month's investigation of quick and cheap ways of getting sensor input into the Pure Data programming environment, using either USB game controllers or ATmega8 microcontrollers and the HID (Human Interface Device) protocol. Participants should bring the AVR/HID boards and/or hacked joysticks from the previous workshop. Those who did not attend the previous workshop are welcome, and ready made sensor boards can be purchased as part of the participation fee. Please RSVP to <m(a)1010.co.uk> if you plan to attend, and indicate whether you will need a sensor input board for Saturday. A few (!) sample sensors will be provided, but participants are encouraged to bring their own sensors (light, pressure, motion, etc...) for experimentation. The Pure Data programming environment will be used to get the sensor information into the computer and map it to different parameters, ranging from MIDI to direct control of audio or video. Windows users should be aware that the possibilities for input on their systems may be more restricted. GNU/Linux and Mac OS X users should not expect any problems. Some links for those interested: http://1010.co.uk/avrhid.html (AVR/HID board documentation) http://puredata.info/downloads (install PD-Extended 0.39 from here!) http://www.sensorwiki.org/index.php/Main_Page (comprehensive list of sensors for musical use) ---What to bring: Essential: 1) Laptop running Linux, OS X or Windows (be advised that Windows users may have fewer possibilities) 2) Pure Data Extended 0.39 installed from: http://puredata.info/downloads (please mind that it is Extended and 0.39!!!!) 3) Soundcard (internal or external, quality a non-issue) 4) Headphones 5) EUR 10 participation fee (+ 8 euros if you need a sensor board) Recommended/Suggested: 1) Sensors of any kind 2) USB game controller of any kind 3) Microphones or other sound inputs 4) Your own project ideas for discussion ---About the Teachers Derek Holzer [USA 1972] began working with Pure Data in 2001. Since then, he has taught and performed with the program across Europe, North America, Brazil and New Zealand. His work focuses on field recording, networked collaboration strategies, experiments in improvisational sound and the use of free software such as Pure-Data. He is currently writing a beginner's manual for Pure Data. http://www.umatic.nl/info_derek.html http://www.umatic.nl/workshops.html http://flossmanuals.net/puredata Martin Howse operates within the fields of discourse, speculative hardware (environmental data in open physical systems), code (an examination of layers of abstraction), free software and the situational (performances and interventions). http://1010.co.uk ---_______ xxxxx_workshops A (more-or-less) weekly series of constructivist workshops emphasising making and connection within the field of the existent.

dialogue box for quit message
by gilberto bernardes 22 Apr '08

22 Apr '08

Dear PD users First my excuses for the silly question, but is quite important for me. Can someone tell me if there is a way to quit PD through a message like (; pd quit) with a dialogue box requesting if I really want to quit, and not suddendly like it happens? Thanks in advance, Gilberto Bernardes www.bernardes7.googlepages.com _________________________________________________________________ Receba GRÁTIS as mensagens do Messenger no seu celular quando você estiver offline.

stk osx

hi, I discovered the experimental stk external in ggee. I tried to compile it first with the latest stk release (4.3.1) which seems to be incompatible, because some files are not more present (RtDuplex.h). but there is also another error, and that stays even after I switched back to stk 4.2.1. nyc-calling:experimental marius$ make -f Makefile.darwin g++ -ggdb -DPD -O3 -fPIC -funroll-loops -fomit-frame-pointer -W -Wshadow -Wno-unused -Wno-parentheses -Wno-switch -I/sw/include -I/Users/marius/devel/pd-rsync/pd-extended/externals/ggee/experimental/stk/include -I/Users/marius/devel/pd-rsync/pd-extended/pd/src -c stk.cpp /Users/marius/devel/pd-rsync/pd-extended/externals/ggee/experimental/stk/include/Mutex.h:65: error: Â‘MUTEXÂ’ does not name a type /Users/marius/devel/pd-rsync/pd-extended/externals/ggee/experimental/stk/include/Mutex.h:66: error: Â‘CONDITIONÂ’ does not name a type /Users/marius/devel/pd-rsync/pd-extended/externals/ggee/experimental/stk/include/Thread.h:62: error: Â‘THREAD_FUNCTIONÂ’ has not been declared /Users/marius/devel/pd-rsync/pd-extended/externals/ggee/experimental/stk/include/Thread.h:90: error: Â‘THREAD_HANDLEÂ’ does not name a type make: *** [stk.pd_darwin] Error 1 did someone get this working on osx already? marius.

Re: [PD] streaming audio

Rob, I have heard of ogg and mp3cast~ but have been unable to find them/ get them to create in pd. any suggestions? are they part of the extended package? I'll start looking again, now that I know for sure that they are around.

Remember that two different notes can share coincident partials, hence harmony/consonance. This is especially true of strings that vibrate in all harmonic modes. > In equal temperament the frequency of those coinciding harmonics turn out to > differ by a few hertz which creates beating, as I'm sure you would know. > If one was able to aurally isolate that beating it would make tuning a lot > easier. The beating will be at a low frequency, just a few Hertz. It may be more difficult to isolate these low frequencies and you wouldn't be able to directly hear them as they are below the frequency threshold for being heard as sound. You could however use them to modulate a third source like noise. > So is it feasible to have an application that does this fairly automatically > from interval to interval as one tunes? It would have to be able to isolate > that beating as it is changed by tuning the notes in real time. I think so. Perhaps some of the guys who understand pitch perception better will have something to say here. It seems like you need to track the fundamental so Hardoffs suggestion of employing [fiddle~] is good. > > I know I'm not explaining this very concisely but I would appreciate it in > someone was willing to hash over this with me.

rank, beginner (actually haven't even begun) with a question
by Jeffrey Atkisson 22 Apr '08

22 Apr '08

Hi, can someone please enlighten me re: what I am calling real time DSP. How possible would it be to create following scenario. 1. create real world acoustic sound (e.g. piano note) 2. mike that sound 3. monitor sound over headphones 4. analyze and process according to analysis in real time (immediate). for example play note isolate per instructions an upper partial/harmonic in that note and equalize (or whatever you would call it) to have just that partial be heard. So that in real time you are hearing just that harmonic. Thanks in advance if anyone is willing to answer this.

pc mac sharing netsend and netreceive
by nick burge 21 Apr '08

21 Apr '08

Hello list, does anyone have experience of sharing data between pc and mac using the netsend netreceive objects or perhaps OSC? Is extra software necessary for example? Scenario: I want to share the data coming off an arduino with my colleague who runs a Macintosh whilst I run a Windows Vista PC. (Since we will be side by side on the stage we could use a LAN cable connection) Nick Burge.

Disconnection Methods in PD
by Jonny Martyr 21 Apr '08

21 Apr '08

Hi Everyone, I was wondering if there is a way to send a "disconnect" message to a subpatch, in the same way that you can send a "connect" message, in order to break a connection between two objects. Does anyone know of a way to achieve this? Many thanks in advance for your help.
