Problems with MIDI input, but only on Linux
by Jim Ruxton 05 Sep '02

05 Sep '02

I'm having some trouble with my midi port shutting down on me under Linux. I am having no problems with Pd midi using windows XP however. I'm using a usb midisport 2x2 interface.The problem happens when I have midi input on both ports of the midisport. Occasionally Pd just stops receiving the data. The only way I can get it back is to close Pd, disconnect the midisport, restart it and Pd. This may be a problem with the Linux driver for the midisport. Since I'm receiving the data via wireless I think I may be getting the occasional non midi data which may be causing the problem, but as I said this doesn't seem to be a problem under windows. I really want to stay in Linux so if anyone has any thoughts on what I might do to fix this I'd appreciate the input. Thanks! Jim

> > - Is there some way to switch to other fonts? > only by editing pd.tk file (atleast @ the moment) Please correct me if i'm wrong, but i thought that in principle all things definable in pd.tk can also be specified from within an external (with sys_(v)gui)?! greetings, Thomas

hi thomas, hi all, 1000x thnx, it works. ok, so heres the first beta of PUFO (PureFont :). it has still only one size (7pt [6x9pix]) and is only in windows FON format, so dunno how you use it on linux/osX :(. but, for win32 just copy the pufo.fon to /windows/fonts directory and replace your pd.tk (0.35-1) file with the attachment. ready to use :) pd.tk changes; changed the font size 8 to 7 (font bomb) and selection of pufo font on size 7. but if you still need courier on 8pt let me know! how to use/select pufo font? open/create a patch and change to font size 7 cheers -andre ps. yes, any comment IS welcome as its still a beta ! ----- Original Message ----- From: "Thomas Musil" <musil(a)iem.kug.ac.at> To: "Andre Schmidt" <andre(a)vju-tv.net>; "PD-dev" <pd-dev(a)iem.kug.ac.at> Sent: Wednesday, September 04, 2002 8:12 PM Subject: Re: [PD-dev] pd.tk [fonts] > Hi Andre > > revision 1.01 > > replace "-font [format -*-courier-----%d-* $font]" by "-font $fontname". > > ############ pdtk_text_new -- create a new text object #2########### > proc pdtk_text_new {canvasname myname x y text font color} { > if {$font < 8} {set fontname [format -*-pufo-----%d-* $font]} > if {$font >= 8} {set fontname [format -*-courier-----%d-* $font]} > $canvasname create text $x $y \ > -font $fontname \ > -tags $myname -text $text -fill $color -anchor nw > # pd [concat $myname size [$canvasname bbox $myname] \;] > } > > but maybe, you don't see a difference with a smaller font then 8. > > good luck > > Thomas Musil > > _______________________________________________ > PD-dev mailing list > PD-dev(a)iem.kug.ac.at > http://iem.kug.ac.at/cgi-bin/mailman/listinfo/pd-dev

Gem install probs

hi all, Being very new (<24Hrs) to linux I'm trying to get pd and Gem running on a Mandrake 8.2 system. I managed to compile pd (which was pretty easy) but now I'm stuck with Gem: when giving the "make" command in ../src/Gnu I get the following error: ---------start for d in ../Manips Â ../Particles ../Base ../MarkEx ../Pixes ../Controls ../Nongeos Â ../Geos ../tv; do \ Â Â echo ""\ Â Â echo "----------$d----------"; \ Â Â cd $d && make || exit -1; \ done Â echo ----------../Manips---------- make[1]: Entering directory `/home/rr/gem-0.87/src/Manips' c++ -c -g Â -fPIC Â -I../ -I/usr/include/glib-1.2 -I/usr/lib/glib/include -I../../../gem-0.87/gltt-2.5.2 -I../../../Desktop/Trash/GemLibs/particle -I../../../Desktop/Trash/GemLibs/liborb -I../../../Desktop/Trash/GemLibs/glm -I/usr/local/include -I..

Physical modelling
by Andreas Sumerauer 05 Sep '02

05 Sep '02

Hello everybody! I'm new to pd and new to this list. Now to introduce myself: My main interest is physical modelling. I was pointed to pd only a few days ago. I have to say I am quite surprised. The installation was not too difficult and with my ASIO Soundcard the thing runs very nicely. Latency is ok for realtime playing and I started rightaway with the implementation of a plucked bass instrument. I think it's quite cheesy (even worse than Steinbergs VB-1, hehe) but please try for yourself. It is available from my website http://www.soundbytes.de/patches/pd/CheesyPhyMoBass.pd there is also a version that uses Ben Saylors envelope module: http://www.soundbytes.de/patches/pd/CheesyPhyMoBass_vadsr.pd hope You like it. best regards Andreas Sumerauer www.soundbytes.de www.dausenkunz.de

hi scott. i made an example of what i think you want to do. please tell me, if i'm wrong. you can draw a filterkernel of 128 samples (time-domain!) and convolute it with any sound you like, ... you can adapt this to your own needs. see attached patch. marius. ----- Original Message ----- From: "J.

External Port From Linux to W2K (fwd)
by Carr Wilkerson 05 Sep '02

05 Sep '02

I have a home rolled external which I ported from Linux to W2K. The external is a physical model of a Tibetan bowl which employs 8 banded digital waveguides. The port was done in Visual C++, and all the appropriate changes were made to the external's code and compiled. pd for W2K v 0.35, appropriately recognizes the external. My machine is a 800mhz P3 laptop. On a Linux 500 Mhz desktop, on which the original external was developed and tested, the audio and (massive) control patches worked fine with minimal notice of processor overload. Problem: On my windoze laptop, with the exact same patches, and the newly compiled bowl external, the processor is max'd out at 100%, causing significant control latency, lethargic graphics, and no sound output. I was wondering if anyone has had similar problems. I somehow think there is a problem, given the significant realtime buffer reading and writing, with the way W2K dll is dealing with the buffers (as apposed to the lean Linux way). I would use Linux for this project if I weren't having to deal with a MIDI interface without a reliable Linux driver. Thanks. Carr

scotty, beam me up a little! you can have the convolution process on two given audio wave-files, thats one thing, but also on streaming data. and the fft-windows can be smaller than the samples or bigger (twice as big, if you like.) it is like a reverb: you can wait until the reverberation of a soundfile is finished or just play and play... the first method could make sense if you have very long and complex wavefiles to have a clean special effect without any glitches or loops. the problem with this method is the handling of large files and a lot of cpu is needed. this cannot be done in realtime, because you only can listen to the sound, if the calculation has finished, but of course it can be done in pd... with the other method you split the wave files in slices and convolute always small parts. this is something different. after the convolution they are put together again. hmm, can you explain again, what you want to do, which sounds to use, ...? marius. ----- Original Message ----- From: "J.
