Run and complile a external
by Enrique Franco 05 May '02

05 May '02

Hi, Somebody knows about a site and/or document with a step by step guide to run a external in PD. I have write the code and compiled in Visual C++. I have put the .dll file in the externals but I guess there are other files that I have to put there..(makefiles?????) I have writtes the code for the example "Helloworld" and there's a message when I run Pd: load_object: Symbol "Helloworld_setup" not found externs/Helloworld: can't load library Cheers, Enrique

GEM: Change buffer without destroying?
by David Sabine 05 May '02

05 May '02

Hello, I'm using GEM to render a number of different visual effects and ONE of those structures requires a gemwin buffer value of "1" while all others work best at "2". These structures don't need to render simoultaneously - but it would be nice. However, when I try to change the buffer size by sending the value to gemwin, the GEM window starts acting erratically. Hence, I'm guessing that the buffer size can only be changed after destroying the gem window before creating a new one (am i right to assume this?) So the question is: How can I change the buffer size of the gem window without destroying the window? sub-question: The gemlist that I'm having difficulty with is similar to gemPixDataSimple.pd from the GEM examples. Why does that type of structure require "buffer 1"? How can that example patch be modified to work with "buffer 2"? Thanks... Dave S

RE: [PD] GEM: Change buffer without destroying?

David, Ben's description is correct. In theory, someone could make it so that you could draw to the front buffer, instead of the back, in double buffer mode. This would allow you get both styles of rendering.

asio device number.
by Matthew Nish-Lapidus 04 May '02

04 May '02

hi, maybe i'm missing something obvious, but... i can't seem to get the -asio flag to use anything but the default device bnumber, which is 0. i've searched through the list archives and tried all the solutions i found, but nothing seems to work. here are a couple of the command lines i've tried: pd -asio -soundoutdev 1 pd -soundoutdev 1 -asio pd -asio 1 ...etc. matt.

hi again, well, i can get audio one-way using 'pd -noadc -sounddev 1'. It gets rid of the 'bus error' message for now. nick -- Dr Nick Fells, Music Department, University of Glasgow, Tel: +44 (0) 141-330 4096 Glasgow G12 8QQ Fax: +44 (0) 141-330 3518 UK. http://www.music.gla.ac.uk/~nick

samples
by Matthew Nish-Lapidus 04 May '02

04 May '02

hi, i have two questions about using samples in PD... 1. is there any way to aviod the puase in audio output while loading files in arrays? i want to be able to have continuous sound even while loading new samples. 2. is there a way to not have to press load before play for the readsf~ object? so you can play the sample over and over again without pressing load each time... thanks, matt.

length of wav header...
by Nick Fells 04 May '02

04 May '02

Hi, sorry, I'll stop flooding the list soon... anyone know the length of the header of a wav file made by ProTools? I'm trying to load samples using Soundfiler, but it doesn't like the PT files ('unknown or bad header format'), so I'm using -raw flag... nick -- Dr Nick Fells, Music Department, University of Glasgow, Tel: +44 (0) 141-330 4096 Glasgow G12 8QQ Fax: +44 (0) 141-330 3518 UK. http://www.music.gla.ac.uk/~nick

Re: [PD] OSX and Tk...
by Nick Fells 04 May '02

04 May '02

Hi all, Latest in the saga... Downloaded Miller's latest release, (test22 for mac osx), tk now works fine without the '-nosound' flag. Problem now is no audio: trying './pd -sounddev 1' gives the following: could not open midi input device number 1: Host error. could not open midi output device number 1: Host error. nchan 2, flags 3, bufs 8, framesperbuf 256 PortAudio on OSX - Latency = 2048 frames, 46 msec Bus error And Pd quits (though the tk window's still there...) Any ideas here? cheers, nick > -----Original Message----- > From: Ben Bogart - FMPM/F1999 <bbogart(a)acs.ryerson.ca> > To: Nick Fells <nick(a)music.gla.ac.uk> > Date: Fri, 3 May 2002 09:45:21 -0400 (EDT) > Subject: Re: [PD] OSX and Tk... > > Same goes for mine... > > On Fri, 3 May 2002, Nick Fells wrote: > > > Hi Michael, > > > > Thanks, yep i got your earlier mail about this - indeed it does say > > > > set pd_nt 2 > > > > But I didn't have to change anything (that's what it says in the current > > 'OSX test' tarball version...) > > > > Nick > > > > > > "Michael A.

Crash with Win2K...
by Peter Warden 04 May '02

04 May '02

Hi all, just a quick note on a crash I've been experiencing as I've been trying to get GEM and some avi playing patches working on my new install of PD. After using a precompiled gem.dll (ver: 0.87), I compiled my own and ran it through the debugger to try and track down the problem. Looks like inside pix_filmNT::realOpen(), AVIStreamOpenFromFile() is returning something non-NULL, but then AVIStreamGetFrameOpen() returns NULL. This is then stored into m_getFrame, which then eventually causes a crash down the line inside the render. I'm guessing from MSDN that the NULL return value is because it can't find a codec for the file? This I'm confused about because both VirtualDub and Media Player are quite happy with the multiple avi's I've tested it with. Anyway, if anyone could shed any light on what's happening, I'd be very grateful. For the moment I've added the following code after line 82 in pix_filmNT.cpp, after m_getFrame = AVIStreamGetFrameOpen(..., and it at least stops the crash from being fatal: if (m_getFrame==NULL) { error("GEM: pix_film: Couldn't decompress file: %s", filename); return; } I'm running on Win2K, SP2, GeForce3 Ti 200, Athlon 1700+, 512Mb. Let me know if you need any more details. Thanks, Pete

[ANNOUNCE] turn the knobs, fix the bugs
by Frank Barknecht 03 May '02

03 May '02

Hi all, somehow I really missed a knob gui object in PD, so I wrote one. Well, in fact, I only changed g_hslider.c a bit. My knob looks very much like the knobs in a popular new audio software made in Berlin. That's intended, because I like those knobs. ::from_the_readme:: "knob" is a new gui object for PD based on the IEMGUI-hslider included in PD. It is only tested on Linux, but it should work on other platforms with little changes. Distribution form is as a patch to PD in version pd-0.35-test17.linux.tar.gz This is the first known bug: knob should be an external! It has at least one other known bug: While moving the knob, the dial line is wrong. Also the computing of geometries needs to be cleaned up and the Properties dialog still includes the not used height entry renamed to NONE, to make clear that this value is ignored. I will fix these bugs someday, but I'll have to dig the hslider code some more. Maybe someone wants to help??? Also maybe some have ideas how to extent the knob, make it more ergonomic and such. Knob is available at http://footils.radio-worldwi.de Screenshots are there as well. Direct download adress is: http://footils.radio-worldwi.de/knob-0.01.tgz It was written reusing very very much IEM code, so props go out to Thomas Musil. ciao, -- Frank Barknecht _ _______footils__
