osc v 0.02 (sendOSC, dumpOSC, OSCroute) for Win32
by Bob Falesch 14 Apr '02

14 Apr '02

here's a new DLL version of the win32 OSC object: http://207.208.254.239/pd/win32_osc_02.zip anyone who in recent days has downloaded the win32 osc DLL should upgrade to this one (btw, the case may be changed for loading, i.e., "-lib OSC"). see the readme file for a release note and source code availability. ______________________ | b o b f a l e s c h | www.zeggz.com/raf/

[ANNOUNCE] shabby~ - a waveshaping PD external
by Frank Barknecht 14 Apr '02

14 Apr '02

shabby~ - waveshaping PD external, probably running on Max, too shabby~ is a waveshaper using Chebyshev polynoms to generate harmonics from an incoming sinewave. The required creation argument will tell shabby~ how many polynoms to which order it should create. Each polynom will then get a signal inlet to specify its amplitude in the signal. You can use shabby~ to have a rather fast additive synth that allows control over the harmonics in the course of a note at signal rate. shabby~ was written by me after finally getting my copy of Dodge/Jerse's "Computer Music" ;) shabby~ uses the flext C++ layer for Max/MSP and pd (pure data) externals. You need at least flext version 0.2.0. I did only include a Makefile for Linux, but using the Makefiles from Thomas Grills idelay~ package, you should be able to write quick Makefiles for other systems as well. Get real shabby~ at http://footils.radio-worldwi.de/get.html Ciao, -- __ __ Frank Barknecht ____ ______ ____ __ trip\ \ / /wire ______ / __// __ /__/ __// // __ \ \/ / __ \\ ___\ / / / ____/ / / / // ____// /\ \\ ___\\____ \ /_/ /_____/ /_/ /_//_____// / \ \\_____\\_____\ /_/ \_\

spaces in messages to symbol object?
by nullpointer 13 Apr '02

13 Apr '02

Hi. I am having a bit of trouble with the following.. the symbol object doesn't seem to like any spaces in a message that it is sent.. It just symbolised the text up until the first space. This is a problem because when using $1 to create a dyamic message you HAVE to have a space in the message! i.e. [12](numberbox)->[mynewcolor= $1](message) -> [symbol] does anyone know how to get around this? (and in a way that is kind of user friendly?) is it possible to have a message using $1 without a space? i.e. mynewcolor$1 (i know this can be done with creation arguments, for a unique arrayname e.t.c.) Thanks for any help Tom http://www.nullpointer.co.uk http://www.dividebyzero.org http://www.orphanrecords.co.uk ________________________________________________________ C:\AUTOEXEC.BAT C:\REM [Header] C:\> C:\>PATH=C:\PERL\BIN;C:\WINDOWS\COMMAND;\C:jdk1.2.2\bin ________________________________________________________ (all suffixes enabled)

help on vbap-config
by Juha Vehviläinen 13 Apr '02

13 Apr '02

Ok, I'll try to explain things a bit.. All you need to change should be in vbap.main.pd. Start by modifying dac~ to use four channels: dac~ 1 2 3 4. Vbap outputs its data in a format quite compatible to matrix~ and matrix from zexy. The matrix~ and matrix arguments specify the number of sound inlets and outlets. For fours speakers, change them to "matrix~ 4 4" and "matrix 4 4". With four inlets to them you can position four different signals. Ok? Next, define_loudspeakers: The first argument is dimensionality. If none of your speakers are elevated, use 2. Next, list the positions of the speakers from -180 to 180. 0 is front, -90 left, 90 right and 180 back. define_loudspeakers 2 -45 45 0 180 This would define fours speakers: left front, right front, front and back. Also, your channels should match the order of speakers. With "dac~ 1 2 3 4" channels 1 and 2 should be the front left and right speakers and 3 and 4 the front and back ones. If you have elevated speakers, their positions are defined with (azimuth elevation) pairs. That is: define_loudspeakers 3 -45 0 45 0 0 45 180 45 Front left and right speakers are not elevated, but front and back speakers are elevated 45 degrees. Use 3 as first argument. That should be it.. I just realized the help file is far too complex and not focused on the relevant stuff, should change that.. cheers Juha ----- Original Message ----- From: "Olaf Matthes" <olaf.matthes(a)gmx.de> To: "Juha VehvilÃ¤inen" <jusu(a)pinktwins.com> Sent: Saturday, April 13, 2002 9:13 PM Subject: Re: [PD] [announce] Vector Base Amplitude Panning > Hi Juha, > [...] > with 4 speakers...). > > Olaf

map map map...
by Krzysztof Czaja 13 Apr '02

13 Apr '02

hi, being constantly informed about (ignored) unmapping may get quite annoying (esp. when in need to frequently switch between virtual desktops). I think either line 831 in u_main.tk (test17), reading bind $name.c <Unmap> {puts stderr map} should be commented out, or replaced with something like bind $name.c <Unmap> {pdtk_canvas_map %W ""} (I have not made any research, though, which way is better, and how the replacement behaves outside of linux...:) Krzysztof btw, there is, at least in my setup, another hostile pd.tk line, 834: after 1 [concat raise $name] but this one hurts (that is: takes ages to complete) only if running Gnome... wonder if nobody runs Pd under Gnome?

Re: [PD] pd-35test17 and audio in and latency?

hi with and without asio, pd (w2konly?) "forgets" 2 channels. if i have -inchannels 4 and -outchannels 2 i can use 2 in and 2 out, and they are working. but still, latency is longer than portaudio prints out. i measured |dirac~| --> |dac~| --> cable connection to the inlet of the pc --> |adc~| --> |table1| against |dirac~| --> |table2| and the difference of the two signals was about 1530 samples. is this the normal value, ... thats what my pd-startup-message says: nchan 2, flags 3, bufs 4, framesperbuf 256 [...] PortAudio : minSize = 128 PortAudio : preferredSize = 128 PortAudio : maxSize = 128 PortAudio : granularity = 0 PortAudio : User buffer size = 256 PortAudio : ASIO buffer size = 128 PortAudio : Minimum BufferOffset for Input = 128 PortAudio : ASIOCreateBuffers with size = 128 PortAudio : InputLatency = 128 latency = 2 msec PortAudio : OuputLatency = 128 latency = 2 msec marius. ----- Original Message ----- From: "joge ." <gboy(a)nycap.rr.com> To: "pd-list" <pd-list(a)iem.kug.ac.at> Sent: Saturday, April 13, 2002 3:15 AM Subject: Re: [PD] pd-35test17 and audio in ? > i am using win2000 with a yamaha DS-XG sounds card on my sony vaio z505ls > laptop . > i have a simliar situation as marius [sme] has , i am not using the -asio > flag . > ..... > .... > .... > .... > > after some testing i have narrowed my problem down to the -inchannels <n> > flag . if i have a <n> value if 2 , then sound in doesnt work . if i use a > <n> value of 1 it seems to work . i even get both left and right channels > it seems in 1 . perhaps the inchannels is not counting from 0 ? not sure . > > joge . > > ----- Original Message ----- > From: "Miller Puckette" <mpuckett(a)man104-1.ucsd.edu> > To: "joge ." <gboy(a)nycap.rr.com> > Sent: Friday, April 12, 2002 1:22 PM > Subject: Re: [PD] pd-35test17 and audio in ? > > > > I don't think so... do you know something I don't?

deleting list items
by Orm Finnendahl 13 Apr '02

13 Apr '02

Hi, is there a way to delete items of a linked list, stored with pd's template/data mecahnism? I couldn't find a way to write-access the pointers of the scalars in a list. The set and get objects just access the value part and you can only read the pointer (and store it in another pointer object). I finally gave up and hacked a linked list structure object in C to be able to do some dynamic storage/retrieval efficiently (I know, it could easily be done in scheme, but it has to be really fast). I would rather do that with standard pd though, especially since I might have to reuse these structures in the future. Yours, Orm
