I think that if you're going to emulate analog electronics using Pd, you will have to create a new subsystem aside the messagesystem and the signalsystem, which will work sort of like the signalsystem but will take into account two-way interaction between components. Analog circuits don't have much to do with dataflow, it's just that most readymade components are made to approximate dataflow because it's a model that is easier to think about than something that needs you to solve linear equation systems just to find what anything is doing. For those who'd rather face the analog electronics, this could be a really cool project. I'm curious how you'd implement the following in Pd: .-[ohm 22]-.------------[ohm 15]-. | | | A ----| `-[ohm 33]-. |---- B | | | `-[ohm 47]-'----------'-[ohm 68]-' such that if a [ohmmeter] gui object is plugged into A and B it will find the right voltage. I don't really know how existing algorithms work. Do you plan to use existing algorithms or come up with more efficient ones? What is the samplerate required at the analog-simulation level in order to be able to produce a pitch like [osc~ 11025] in a rather faithful way? I didn't distinguish inlets and outlets in the above diagram. This is because a resistor doesn't distinguish between inlets and outlets. In your system, what would be considered an inlet and what would be considered an outlet and why? I copied this to pd-list because I don't see anything off-topic in the idea... _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada

PixelTANGO requirements?
by Kyle Klipowicz 08 May '06

08 May '06

Hi guys/gals~ I'm starting to get into pixelTANGO, after all the neat video freakout stuff that's been appearing on the list. I've got it running and everything, but can't get the List_Files module to list the directory. I noticed that there is a py object in the code: do I need pylib or whatever it's called? I added the scripts folder to my path, but can't get it to work! Thanks for any help, ~Kyle -- http://theradioproject.com http://perhapsidid.blogspot.com (((())))(()()((((((((()())))()(((((((())()()())()))) (())))))(()))))))))))))(((((((((((()()))))))))((()))) ))(((((((((((())))())))))))))))))))__________ _____())))))(((((((((((((()))))))))))_______ ((((((())))))))))))((((((((000)))oOOOOOO

change to pd-ext
by João Miguel Pais 07 May '06

07 May '06

Hi, I am now changing from pd "normal" to pd "extended" (latest test3) on windows, and wanted to report some things: - /bin/pthreadVC.dll was missing - pd started anyway after complaining. I copied the file from the previous installation and everything was fine. - scale gem/maxlib clash (on a separate thread) - I'm used to having a .bat file for different configurations of pd (different sound cards, etc.), so I find the registry parameters not so flexible - in pd you can only "officially" set 10 paths/libraries. I deleted all variables from the registry, as I won't use them. Maybe a handy feature would be not just a more flexible/dynamic tcl/tk menu with all options there, not just a flag field, but also the possibility to save different configurations: pd -preset 1 ? It's always possible to do different .bat files, but it would maybe cleaner that way (?). - as usual, I keep an updated 0.INTRO.txt file. I will try to update it to pd-ext asap, and leave a copy on my pured.org page (might take a while) - the following dlls from unauthorized couldn't be loaded: playlist, sonogram~*, stk*~ - in /doc/4.audio are all available .pd files there? In my other version they went to K06, here only to G09 - the following externals couldn't be found: bartlett~, blackman~, connes~, cosine~, gaussian~, hanning~, hamming~, kaiser~, lanczos~, welch~, bthresher~, buzz~, the fftease library for pd, cverb~, exp~ (from gge?) - is there any option to define the start position of the pd window?

emulating early video synths - sync
by Paris Treantafeles 07 May '06

07 May '06

Hello List, I've created a few patches with PD/GEM to emulate early video synths such as the Sandin, etc. which I'm quite happy with. At the heart of these patches is pix_sig2pix~ One thing I can't figure out though has to do with preventing the image from "rolling" - i.e. to stand still. The early video synths did this by having a "sync" input to oscillators. So if you fed one oscillator a vertical sync (~60 Hz) you would get stationary vertical bars whose width would depend on the main frequency of the oscillator. Doing this with another oscillator receiving a horizontal sync (~1500 Hz) results in horizontal bars. By mixing these and perhaps another (and adjusting the attenuation of these), various shapes appear. I can get all of this and more (e.g. add some filters for subtractive synthesis) but what I'm missing is how to do the sync correctly. Trying various values as reset inputs to say "phasor~" doesn't do it. I'm wondering if this is in fact related to blocksize~ instead. e.g. should the reset values of the oscillators be related in someway to the value set in blocksize~ Does anyone have any ideas about this? Thanks for any suggestions! Best, p

How can I get PD to address more than two channels?
by Maik Hester 07 May '06

07 May '06

Dear members of the pd list, I just wrote a simple patch to output 8 different osc~ signals to 8 channels of my Hercules FW 16/12 Interface. Unfortunately PD refuses to address more than channels 1 and 2 although I have set the number of channels to 8 resp. 16 in the audio settings. How can I get PD to address all the recommended 8 channels? Thanks for your help, Maik.

Tuning a Mac
by Chuckk Hubbard 07 May '06

07 May '06

I've had this problem before, can't recall if I solved it. This Mac happens to be playing flat, about a half-step. I tested a 440 Hz tone from a keyboard (I checked its mastertune and scale), and to get Pd to play that pitch takes about 451.2 (less than a half step, but way off). I checked the sampling rates, everything is set to 44.1 kHz. And the ratio doesn't correspond to 48000/44100. I know it's not just the keyboard, because I noticed it in a composition first.. How could something like this happen? -Chuckk -- "It is not when truth is dirty, but when it is shallow, that the lover of knowledge is reluctant to step into its waters." -Friedrich Nietzsche, "Thus Spoke Zarathustra"

How to remove duplicate elements from a list???
by David Powers 06 May '06

06 May '06

Hello, Is there a way to remove duplicate elements for a list? I can figure out how to do it in code, but trying to figure out a way to do this with lists just makes my head hurt. I want to do Boulez-style pitch-set multiplication with lists, and typically after such an operation, duplicate elements are removed. I already made an abstraction called "Schoenberg" which I will post shortly, which allows one to do basic serial operations using lists (ie. transposition, retrograde, inversion, and rotation, all using one simple abstraction). I know that serialism has been out of style for 40 years, but nevertheless those methods make a lot of sense to have available, if one is making nontonal generative/aleatoric music. ~David
