Pd-extended 0.41.4 release candidate 1
by Jeff Sandys 17 May '09

17 May '09

This change kind of works for me. Using: Fedora Core 9/i386: Pd-0.41.4-extended-rc1-planetccrma9-i386.tar.bz2 with Fedora 10 and 2.6.26.8-1.rt16.1.fc10.ccrma.i686.rt kernel. The install per your instructions ran quickly with no problems. The default font size 12 is noticeably smaller than font size 12 in the editor or terminal, more like size 9. The relation of box size to font size is uneven, size 10, 12 & 16, just fits, but size 8, 24 & 36 have extra space between the end of the text and the box, and size 8 font is impossibly small to read. Why does the tk program list 10 different sizes when the pd font choice box only lists 6 (size 8 10 12 16 24 36)? What (or where) is the relation between this foreach and the pd font selection dialog? -- Jeff > OK, I got the font size fixed!

Maximum size of arrays (gui version) when using bezier / polygon
by Martin Schied 16 May '09

16 May '09

Hi all, I'm using arrays to display contents of 1024 sample wide audio blocks. When using bezier or polygon mode all values of samples greater than 1000 are not visible anymore. Their values are still there. Is there a reason for a 1000 pixels limit for bezier or polygon mode? Is it extendible to a "digital age compatible" 1023? Attached patch demonstrates the limit. I had this on several different versions of pd extended, also current release candidate (don't know about vanilla). ubuntu 8.04 Pd version 0.41-4extended-rc2 compiled 08:11:33 May 15 2009

[expr if ($f3 > 0, $f1 + $f2, $f1 - $f2)] will give you only one outlet. You can even nest if statements: [expr if ($f3 > 0, $f1 + $f2, if ($f3 < 0, $f1 - $f2, 0))] -Jonathan

message routing question
by Chuck Wiggins 16 May '09

16 May '09

I'm fairly new to PD, and have a behavior in a patch that I can't understand - perhaps someone can enlighten me. I've reduced the problem down to a simpler patch layout - see attached file. My goal is to read midiin messages from a file via a qlist object, and route them based on channel. I matched up unpack and pack objects to transpose the midiin arguments so I could subsequently route based on channel. But I think a bang event is firing on the pack before it has all the arguments - the first print statement is not the first message from my file. I tried even introducing a 1ms delay before sending the leftmost argument to pack, but that soon got out of sync. Also tried a few approaches storing in floats. Any suggestions? I'm sure it's a basic PD behavior that I just don't quite grasp yet. Running the attached patch will show the sequence below. The print statement from the [route 4 1 2 3] object is displaying before the one from the [route notein], and the first value it shows - "42 0" - is not the first midiin message from my file - in fact it's the last.. print: 42 0 print: notein 50 127 4 print: 50 127 print: notein 50 0 4 print: 50 0 print: notein 45 127 4 print: 45 127 print: notein 45 0 4 print: 45 0 print: notein 47 127 4 print: 47 127 print: notein 47 0 4 print: 47 0 print: notein 42 127 4 print: 42 127 print: notein 42 0 4 Thanks much, Chuck

[expr] for "if, then, else"?
by Derek Holzer 15 May '09

15 May '09

I would like to use [expr] for an "if, then, else" statement: If $f3 > 0, then $f1 + $f2, else $f1 - $f2 In the help for [expr], I see the following: [expr $f1; if ($f1 > 0, $f1 * 2, 0); if ($f1 <= 0, $f1 / 2, 0)] So I try: [expr $f1, $f2, $f3; if ($f3 > 0, $f1 + $f2, 0); if ($f3 < 0, $f1 - $f2, 0)] but it doesn't create. I also tried without the final ",0" in each statement, and also this way: [expr $f1, $f2, $f3; if ($f3 > 0, $f1 + $f2, $f1 - $f2)] Can someone explain to me the proper syntax for this? D. ps... gotta love the fact I can copy/paste text in and out of objects etc these days! -- ::: derek holzer ::: http://blog.myspace.com/macumbista ::: http://www.vimeo.com/macumbista ::: ---Oblique Strategy # 142: "Shut the door and listen from outside"

Re: [PD] Pd-extended 0.41.4 release candidate 1
by Matt Barber 15 May '09

15 May '09

I was about to write about the same font problems for the release candidate on fedoras 9 and 10 -- it finds bitstream vera just fine, but the fonts stick out of the boxes in the same way. If this is because of Tcl/Tk 8.5, that's not going to be an easy one to fix, since Fedora's moved ahead with 8.5 -- maybe it's possible to install an 8.4 compat version. Either way, the current fedora/ccrma nightly builds are against 8.5. PS In Pd-extended on fedora 8 the bitstream vera font is not found (I posted on this several months ago)... F8 doesn't have tcl/tk 8.5 so newer binaries don't work. At any rate, I haven't found a solution to this one... maybe I'll try adding a symbolic link in the path listed in the source file. > Date: Thu, 14 May 2009 21:01:32 -0400 > From: Hector Centeno <hcengar(a)gmail.com> > Subject: Re: [PD] Pd-extended 0.41.4 release candidate 1 > To: Hans-Christoph Steiner <hans(a)at.or.at> > Cc: Pd List <pd-list(a)iem.kug.ac.at> > Message-ID: > <695e1a650905141801k403cb7d1x40cf866d22e48b97(a)mail.gmail.com> > Content-Type: text/plain; charset=ISO-8859-1 > > OK, it seems that I got it to build in OpenSuse 11.1 and it seems that > it was much less effort than when I did it on OpenSuse 11.
