[comport] like object for usb?
by B. Bogart 25 Sep '07

25 Sep '07

Hey all, I'm looking at rs232 controllable PTX systems, and they seem to be more and more usb and less and less rs232. So is there anything like [comport] that allows one to send bytes to usb devices? I think a general mechanism, like [comport] that would work for all usb devices would be better than a slew of objects for each specific usb device... Thoughts? .b.

Hi there, I finally got to grips with CVS and sorted out the errors I made last week in uploading messiness to the repository. Should all work now (well, my bit anyway :D ) Best, Ed Lone Shark "Aviation" out now on http://www.pyramidtransmissions.com http://www.myspace.com/sharktracks --------------------------------- For ideas on reducing your carbon footprint visit Yahoo!

pdlua: volatile objects...?
by zmoelnig＠iem.at 23 Sep '07

23 Sep '07

hi list, hi claude. using the great pdlua extension it is easy to create object(classe)s in lua. however, the class is registered on loading and then kept in memory of pd. for rapid prototyping it would sometimes be nice to be able to do a "volatile" load (just like abstractions) of an object: so when i change the code and re-instantiate the object, i will get a new version. would this be easy to implement? (e.g. by just using another function to register as pd-object: volatile() instead of class() or whatever...) fmga.dsr IOhannes ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

more on the 12 point font mystery
by Hans-Christoph Steiner 23 Sep '07

23 Sep '07

I decided to take Pd out of the equation, so I did a quick test using just Tcl/Tk on Mac OS X and Ubuntu Studio. It looks like it confirms what I am talking about: for some reason 12 point is big on GNU/ Linux. So I think we can handle this by forcing 12 point fonts to actually use 11 point on GNU/Linux machines. Here is the script and the screenshots: http://pow.idmi.poly.edu/~hans/pdfonts/fonttest/ .hc ------------------------------------------------------------------------ ---- If you are not part of the solution, you are part of the problem.

[ANN] new external: tracker
by federico 22 Sep '07

22 Sep '07

hi dataflowers, today I release a new external: tracker if I have to describe it, I would say it is a 2D grid editor, with file load/save support, keyboard entry support, dynamic resizing, tracking of the row being read (see help patch attached) you can get it there, or in CVS under the externals/ffext/tracker directory. http://www.puredata.org/Members/federico/externals/tracker-0.2.tar.gz please report feedback about use, bugs, and possible improvements -- Federico Ferri

error in maskxor in CVS
by Tim Boykett 21 Sep '07

21 Sep '07

Hi, compiling pd-extended from CVS, I found a small and new error. in the directory externals/ekext/maskxor there is a subdirectory v3. This contains a pd_linux file that has a name clash. This directory was created 49 hours ago, so I presume it is an archive version of the correct and updated maskxor and should be deleted. Once deleted, make works. I hope someone can fix this in CVS. Cheers, tim

[ pure-data-Feature Requests-1798795 ] Allow reading [bag]'s content without reset
by SourceForge.net 20 Sep '07

20 Sep '07

Feature Requests item #1798795, was opened at 2007-09-20 16:32 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478073&aid=1798795&group_… Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: puredata Group: None Status: Open Priority: 5 Private: No Submitted By: Frank Barknecht (fbar) Assigned to: Nobody/Anonymous (nobody) Summary: Allow reading [bag]'s content without reset Initial Comment: Suggestion: I think it could be useful to add a method to the core-object [bag] which allows one to take a peek into the current content of a [bag] without destroying that content at the same time. Kind of like the existing "flush" method, but without the "clear"-part. I'd propose to just use the "bang" method for this. This could make [bag] more useable as a general purpose container, whereas now it's like an "all-or-nothing" bag: While you can add to and remove from the bag, you can only take a peek at what's currently inside the bag by emptying it. A non-destrictive peek method would be especially useful to construct some of the monophonic voice allocation algorithms. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=478073&aid=1798795&group_…

Who made pddplink look like a hyperlink?
by B. Bogart 19 Sep '07

19 Sep '07

Hey!!! Who fixed PDDP link?!?!!? (to look like a real link!) A huge thanks to whoever did the work. I have a couple of suggestions though: 1. It should turn purple when the link is visited (as the ol standard) (-fill #551a8b) 2. It should have an underline to look like a real hyperlink, so people don't think of it as a roll-over comment or something. This is more tricky, an "underline" font could be useful in PD in general, which would mean adding something like the following to the pd-extended font hacks in pd.tk: (or it could be done in pddplink and be a private underlined font) # start Pd-extended font hacks ----------------------------- # Pd-0.39.2-extended hacks to make font/box sizes the same across platform puts stderr "tk scaling is [tk scaling]" tk scaling 1 # this font is for the Pd Window console text font create console_font -family $defaultFontFamily -size 12 -weight normal # this font is for text in Pd windows font create text_font -family {Times} -size 14 -weight normal # for text in Properties Panels and other panes font create highlight_font -family $defaultFontFamily -size 14 -weight bold # Underlined text for PDDPlink++ font create text_font_underline -family {Times} -size 14 -weight normal -underline 1 # end Pd-extended font hacks ----------------------------- The itemconfigure -font text_font_underline should underline something. 3. Marius mentioned it not working in GOP, I've not had a chance to look at it, but my popup external used to not work in a GOP, and that was fixed (by Guenter Geiger I believe?) so that same fix in popup should be easy to add to [image] and [pddplink] to make them work in GOPs. (Not to mention Yves externals) 4. Seems pddplink is not linking to local file (.pd files) properly, it does not seem to do anything when that is the target. (with file:// or just the absolute path /usr/bleh/file.pd) Thank you!!!!

ask for cvs access
by federico 18 Sep '07

18 Sep '07

hi all, recently I got some practice also in programming graphical widgets for puredata, so here's my request for write access to a directory in cvs. (my sourceforge.net's account name is federico__, like my irc alternative nickname) a short note about me: I am student in computer science engineering. this summer got a temporary work as IT admin in a danish tlc company. using pd since 5 years and use it for music, making effects and software synthesizers, sequencing data, and interfacing it with hardware (both midi & electronic devices like arduino) and I'm very happy with it. you can find something more about me&pd on my pd member page: http://www.puredata.org/Members/federico I am also the maintainer of pd-overlay - http://pd-overlay.sf.net - an effort about providing updated pd externals & related software "packages" (really: ebuilds) on Gentoo Linux OS externs I'm going to commit: grid: a gui 2d grid editor made esecially for editing/sequencing lists of floats, it should be a nice frontend for iemmatrix (I'm planning to add iemmatrix-specific messages, so that is more straightforward) notehigh/notelow: externals for getting monophonic midi from [midiin] ... and more to come!!! right now I'm interested in gui programming stuff, but expect any kind of externs!! ciao!

Re: [PD-dev] audioindev with several devices

David, In my audiopint setup, I'm using 4 USB iMics in a cheapo USB 1.1 hub. I use all 4 stero inputs and the one single stereo output of the first iMic. I haven't confirmed it, but I'm confident that fully duplexed stereo on all 4 devices would go over the theoretical 1.1 bandwidth (my setup does not). I multiplex the 4 cards into a single virtual card using the attached asoundrc (which should be named as ~/.asoundrc). I am successfully using this 8-in-2-out virtual card with jackd 0.103.0 (realtime) and pd 0.40-2 (realtime). Jackd > 0.102.20 is required to pick up MMAP_COMPLEX, which allows memory mapping multiple multiplexed cards (??). My jackd usage is: jackd --realtime -d alsa -C capture8 -P iMic1 -p64 -n2 and then I make sure I start pd with -jack -inchannels 8 -outchannels 2 (and other less relevant params). I'm pretty sure the clocks aren't exactly synchronized (I would appreciate confirmation or refutation), but it hasn't really caused me any pain yet, even though I should likely back -p64 down to -p128. I'm pretty sure I had limited success getting pd to work in alsa mode with the given .asoundrc...but to be honest, my focus was on jack first. -jason http://noisybox.net pcm.iMic1 { type hw card 0 } ctl.iMic1 { type hw; card 0; } pcm.iMic2 { type hw card 1 } pcm.iMic3 { type hw card 2 } pcm.iMic4 { type hw card 3 } pcm.capture8 { type multi; slaves.a.pcm hw:0 slaves.a.channels 2; slaves.b.pcm hw:1 slaves.b.channels 2; slaves.c.pcm hw:2 slaves.c.channels 2; slaves.d.pcm hw:3 slaves.d.channels 2; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave b; bindings.2.channel 0; bindings.3.slave b; bindings.3.channel 1; bindings.4.slave c; bindings.4.channel 0; bindings.5.slave c; bindings.5.channel 1; bindings.6.slave d; bindings.6.channel 0; bindings.7.slave d; bindings.7.channel 1; } ctl.capture8 { type hw; card 0; }
