In messages $-names get expanded by evaluating the incoming messages. They have to begin with $ and a number as well. But $1-bigsample in an object and $1-bigsample in a message can be different! -- __ __ Frank Barknecht ____ ______ ____ __ trip\ \ / /wire ______ / __// __ /__/ __// // __ \ \/ / __ \\ ___\ / / / ____/ / / / // ____// /\ \\ ___\\____ \ /_/ /_____/ /_/ /_//_____// / \ \\_____\\_____\ /_/ \_\

Dear list. I've put on http://iem.kug.ac.at/pdwiki/ a new release of the documention dealling with pd internal messages. you can direct download from here : http://iem.kug.ac.at/pdwiki/stuff/pd-msg_04.tar.gz Here a brief resume : 1) Thoses msg are sent directly to pd (pd selector) or to a loaded patch (pd-patch.pd selector). all thoses msg has to be finnished by a ";" you can test them using : in the file menu : message pdsend the tclsend2pd in the 4.msg_from_tcl folder. Thoses message allows you (examples): To control pd without the gui : Take benefit of the no-gui option open a patch via socket... (tcl, python, sh, c++,...) modify or create new patch Create patch that will create some other Deals with massive polyphonie (100 osc~ or more...) load patchs from an other construct generative patch Create new gui etc... 2) Here an (today incomplete) list of those msg : The list of msg that pd can manage : dsp x; (turnning dsp on & off) audiostatus; open patch path ; quit + many some more that I don't know... The list that a patch can manage : obj x y text in the object ; msg x y text in the message ; floatatom x y width lowerLimit upperLimit ; text x y text in the comment ; graph array x y ??? ; scalar ???? ; connect n°OfFirstPatch? n°OfOutlet? n°OfSecondPAtch n°OfInlet? restore click motion mouseup key menusave menusaveas menuclose saveto tidy texteditor cut copy paste duplicate menufont font find findagin findparent editmode loadbang print relocate vis pop + mabe some more that I don't know... 3) Here the map of the documentation : 1.msg_and_patch describe msg that can be sent to patch. contains pd files 2.msg_and_pd describe msg that can be sent to pd. contains pd files 3.pdscript it's sh scrip using pdsend to create patch into pd. pdscript has been done by Guenter Geiger contains it's own readme + files. 4.msg_from_tcl/tk decribe how to use tcl/tk to create, open patch, etc... 5.Examples Contain an example of how a "obj x y myOsc~" message can be use to deal with massive polyphonie 4) Releases : release 0.4 : pd-msg_04.tar.gz add many message : the events messages the menu messages the cut&paste msg, etc... complete the polyphonie example release 0.3 : pd-msg Rearenge patch & examples in diferents directory. add polyphonie examples add tcl scripts... release 0.2 : self-generation add messages to open and close patch. release 0.1 : self-construction first release 5) To do list : add all msg that are not here. some are not well explain or not explain at all.

local arrays again...
by Nicolas Lhommet 14 Aug '01

14 Aug '01

I got a patch that contains and uses an array called "foo". If i want to use several abstractions of it in an other patch, i can't do it because foo is then mulitply defined. Any solutions better than passing a different name for this array to the different abstractions ? This has been discussed here already, but I still don't know how (or if) I can get really local arrays. BR nicolas

About notebook again but with PD
by Andrey Savitsky 14 Aug '01

14 Aug '01

be careful ... laptop+pd = total pd addiction. / G.G.Karman well, i have tested PD on a notebook ( thanx to everybody who was answerimg on my question about quality of sound. it turned out that my new lap is nice, there is no any extreme electrical noices on the output ( if the MIC input is stay 'mute' )). and i got a trouble. something wrong with recording from the | adc~ | module to the array (this chain used in patches which allow to record the own sample, | adc~ |----| tabwrite~ array | ). it does not happened, the array was clear. meantime i can read data from file to the array. it does work. PD said me during startup: there is no midi input signal. ok. i know. and i use WIN'98 SE. (on another computer with WIN'98 everything is ok) maybe, the reason is lack of the LINE input (exclude the MIC input) on Crystal soun card? need your help. andrey

Soundfile playback
by viridian productions 14 Aug '01

Hi all, Using qsample, I am unable to read in a .wav (not recorded through PD) to an array. Can PD playback soundfiles recorded in other programs such as Wavelab? Thanks in advance, Shaun __________________________________________________________________ Get your free Australian email account at http://www.start.com.au

Re: [pd] hyperbolic trigonometry
by Shahrokh Yadegari 14 Aug '01

14 Aug '01

"expr" (which you can find in the extra directory of pd as extra/expr~) has the hyperbolic trigonometry functions built in. So: "expr sinh($f1)" and "expr cosh($f1)" should do what you want. Hope this helps, Shahrokh. On Sat, 4 Aug 2001, Shadi el-Hajj wrote: > hello everyone, > do you know where i can find hyperbolic trigonometry objects (especially > sinh and cosh).

Max's URN?
by David Casal 13 Aug '01

13 Aug '01

(anon cow steps outta shadows) Hello All, Can anyone advise on how to replicate the URN object from Max in PD? And while we're at it, COUNTER and DRUNK? The PD-Lib project at Sourceforge haven't got to it yet...I tried with != and == constructs, even tried to do Anti-bis from RTC-Lib out of Rowe's machine musicianship, but I guess my pd skills aren't up to it yet. The main problem was trying to get the equivalent of: if ($i1!=$i2) then $i1 else out2 bang to work in PD. Tried expr (this is where I belate dumbness, surely) with no success. There's gotta be an easy way...right?

block~ <vecsize> <overlap> <downsamplefactor>
by IOhannes m zmoelnig 13 Aug '01

13 Aug '01

hi miller ! hi list ! i changed the pd-code to support downsampling in sub-patches (no upsampling yet). the upsampling method for the outlets is still very simple (set samples inbetween to zero) but it fits my current needs. i tested the code both with pd-034TEST4 and pd-033PATCH2. it is not likely to work with sources prior to pd-033. --> help-patch+sources are attached (it's only 14k, so i hope nobody minds) working with pd-034TEST4 is sometimes painful. pe when trying to "find -> last error ?" pd will crash when the patch-window that hosts the error is closed. mfg.v.drtz IOhannes
