creating new breakpoints in "scalars" with the GUI
by Hans-Christoph Steiner 21 Apr '04

21 Apr '04

So I am in the processing of figuring out how to manually edit "scalars" (core part of Pd data structures). I was wondering whether anyone knew if there is a way to create new breakpoints when editing "scalars" with the GUI. .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

Re: [PD] hdsp & pd (again..)
by thewade 21 Apr '04

21 Apr '04

Preface: I am running Hammerfall hdsp multiface on a dell i8000, using FC2t1 and the standard 2.6.4 kernel > - what is the best interface to use an hdsp with ? oss, alsa, jack ? > - what is the typical nice setting for pd with an hdsp > (blocksize/latency) ? what latency do you usually have ? IO is right, there is no real way to run the hdsp on oss, though oss emulation as done via the kernel seems to work fine for me. Alsa, and jack on top of alsa works for me. The jack I run is this, for pd: sudo jackd -d alsa -d hw:1 -r 48000 -p 256 Which should give me a 256/48000 sec buffer of latency (approx 5msec). Takashi\'s latency testing module says that my machine can go to 3.9 msec latency http://www.aproximation.net/test1/ > - is there any objective/obvious reasons to not use a 2.6.x kernel ? No. the 2.6.x kernel works better for me, though I have heard some people complain of larger latency. I have no such problems. If anything my latency went DOWN, though I wasnt using any of the super-duper kernel patches for 2.4.x... > - as modern computers/devices handles irqs in a more smart way now, > would it make a \"real\" difference to have the hdsp set in a higher IRQ > number? Im not sure about what your talking about here, but I have seen some texts about modifying irq\'s to reduce latency. Ive had to do no such thing. The hdsp worked \"out of the box\" for me, after some attempts at configuring the kernel correctly. the .asoundrc and esd.conf file helps a lot too, for standard apps like mozilla and xmms (though xmms worked in oss emulation too). I didnt get the xmms-jack plugin to work though. It would be nice to listen to xmms while coding pd... Hope this helps! -thewade

hi there: thanks for your help, but i am still at bit at lost. here is what i got. please correct me where i am wrong. 1: put below into a text editor and save it as .pdrc -path /home/sonicvariable/pd-externals/cyclone:/home/sonicvariable/pd-externals/my_pd_externals -lib zexy:cyclone 2. call it from the terminal as '~/.pdrc' i got 'permission denied' at this point, and am i calling it correct? many thanks yours CHUN

Problem Compiling VST~
by PAYLING David 21 Apr '04

21 Apr '04

Hi I am attempting to compile and run the VST~ object from Thomas Grill but have a couple of problems. The first one is that the version 1.4 (no 1.5?) will not load into MSVC .NET 2003, but the 1.3 version will. The message I receive is that the file is corrupt even though I can open and read it in a text editor. When I run the 1.3 version I get a message from 'cl.exe' reporting there is no disk in the drive which repeats around 100 times and can only be removed by clicking the 'continue' button furiously. When it finally gets to the end there seem to be some errors in the code as shown below. ------ Build started: Project: vst, Configuration: Debug Win32 ------ Compiling... VstHost.cpp PopupWindow.cpp WINVER not defined. Defaulting to 0x0501 (Windows XP and Windows .NET Server) d:\PD2\vst~\src\PopupWindow.cpp(29) : error C2039: 'OnEditorClose' : is not a member of 'VSTPlugin' d:\PD2\vst~\src\VstHost.h(43) : see declaration of 'VSTPlugin' d:\PD2\vst~\src\PopupWindow.cpp(73) : error C2660: 'VSTPlugin::GetEditorRect' : function does not take 0 arguments d:\PD2\vst~\src\PopupWindow.cpp(74) : error C2039: 'getX' : is not a member of 'VSTPlugin' d:\PD2\vst~\src\VstHost.h(43) : see declaration of 'VSTPlugin' d:\PD2\vst~\src\PopupWindow.cpp(74) : error C2039: 'getY' : is not a member of 'VSTPlugin' d:\PD2\vst~\src\VstHost.h(43) : see declaration of 'VSTPlugin' d:\PD2\vst~\src\PopupWindow.cpp(105) : error C2039: 'setPos' : is not a member of 'VSTPlugin' d:\PD2\vst~\src\VstHost.h(43) : see declaration of 'VSTPlugin' EditorThread.cpp WINVER not defined.

It is not a script.

Re: [PD] Wav file corruption with writesf~
by thewade 20 Apr '04

20 Apr '04

> You don\'t actually describe the failure: noise? silence? error generation? I did in a previous email, sorry I left it out this time: Lame gives me a segmentation fault. aplay cant read non-pcm coded files (I was using 32bit float files as sugguested by another lister). > Debugging steps: Do aplay and lame play: Audacity-generated Tone wav files? lame -h -b 192 audacity-test.wav audacity-test.mp3 LAME version 3.95 (http://www.mp3dev.org/) Using polyphase lowpass filter, transition band: 20323 Hz - 20903 Hz Encoding audacity-test.wav to audacity-test.mp3 Encoding as 48 kHz 192 kbps single-ch MPEG-1 Layer III (4x) qval=2 Frame | CPU time/estim | REAL time/estim | play/CPU | ETA 0/1252 ( 0%)| 0:00/ 0:00| 0:00/ 0:00| 0.0000x| 0:00 Segmentation fault aplay -D hdsp_analog audacity-test.wav Playing WAVE \'audacity-test.wav\' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono (ok, so I was wrong about aplay) > Debugging steps: Do aplay and lame play: Windows Sound Recorder-generated > wav files? lame sndrec32-test.wav sndrec32-test.mp3 LAME version 3.95 (http://www.mp3dev.org/) Using polyphase lowpass filter, transition band: 8269 Hz - 8535 Hz Encoding sndrec32-test.wav to sndrec32-test.mp3 Encoding as 22.05 kHz 32 kbps single-ch MPEG-2 Layer III (11x) qval=3 Frame | CPU time/estim | REAL time/estim | play/CPU | ETA 76/78 (97%)| 0:00/ 0:00| 0:00/ 0:00| 19.853x| 0:00 average: 32.0 kbps ReplayGain: +29.4dB aplay -d hdsp_analog sndrec32-test.wav Playing WAVE \'sndrec32-test.wav\' : Unsigned 8 bit, Rate 22050 Hz, Mono So, lame only works with windows generated files. I was wrong about aplay. Aplay only needs 16bit signed files...(sorry) I have also tried recording something in linux:pd:writesf using 32bit float files. Then I use audacity to convert to signed 16bit, as soundforge and sox cant open IEEE standard float files. Soundforge on widows is used to open, and then save as the soundfile. That doesnt even fix the file! The only thing that has worked for me in the past is using the default writesf:signed 16bit format, then copying to windows, using soundforge to save-as, then copying back to linux, and doing lame and cdrdao. I also seem to remember that when writing files, using writesf~, in windows, then opening in soundforge and saving, soundforge prompts me that there was some extra data in the file... Is there some way to test this theory of the fact chunk, some tool in linux to view binary data headers like these? Is there some way to repair the file by inserting this chunk (should this be the case:linux fix)? Has anyone else had this problem? All I want to do is to be able to write a soundfile to disk in a loseless format, rip it to mp3 and/or burn it to cd. I can record a file to disk using writesf~, but cdrdao and lame cant open it. Is there some modification to writesf in d_soundfile.c that I can make to add this fact chunk, to see if this is the problem? Thanks for the help! -thewade
