[PD-announce] [pd-fileutils] released, a command-line tool for managing pd files
by s p 26 Feb '13

26 Feb '13

Hi all! I am pleased to announce that I just released the first working version of pd-fileutils (https://github.com/sebpiq/pd-fileutils) which is a node.js package and a command-line tool for fiddling with pd files. Right now, the command-line tool only allows you to render .pd files to SVG, but expect more functionalities in the future (I am open to suggestions). If you know JavaScript and node.js, you can also use the API for scripting operations with your pd files. Right now, it can only parse .pd files to a standard JavaScript object, which you can then manipulate easily with JavaScript. This library is a by-product of the WebPd project ( https://github.com/sebpiq/WebPd), which aims at running Pure Data patches on the browser. It is also a proposal for an alternative file format for Pure Data, based on JSON. There was a discussion about that on pd-dev : http://lists.puredata.info/pipermail/pd-dev/2012-06/018436.html and I would like to start it again ;) Cheers! Sébastien Piquemal PS : there will definitely be bugs, so don't "hesitate" to report them :) _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

pd META extension
by Jonathan Wilkes 26 Feb '13

26 Feb '13

Hello list, I'd like to extend the syntax of the xlet metadata in the [pd META] subpatch. Currently something like [clip] has this for the inlets: INLET_0 float list INLET_1 float INLET_2 float That gets picked up by the autotips which display the methods in the tooltip. However, for objects that have multiple xlets like [clip], an xlet tip would be more helpful if it included a one or two word description of what the inlet is for. So when the user hovers over the middle inlet the tip can also say something like: Inlet 1 of clip (low value): float and for the right inlet: Inlet 2 of clip (high value): float I just need some clear syntax for separating the inlet description from the methods. Idea #0: semicolon Example: INLET_1 float; low value Nice because there is no chance of ambiguity, since the semi can't be part of a method name. Unfortunately it forces a newline. The semicolon + description part would be optional so there's no need to change any of the current docs. Plus it's easy to parse. Thoughts? -Jonathan

Hi all! So, I'm going to Tokyo next week to present at the 100th Pecha Kucha Night.

So, I would love to get to know people from the PD community in Tokyo, visit media labs and hackerspaces if there are any. Any suggestions? best, Leandro

Slice//Jockey2 beta, compatible with Pd-E 0.43
by katja 26 Feb '13

26 Feb '13

Finally I have a public beta of Slice//Jockey2 available. Slice//Jockey is a live-sampling tool for Pd-extended. The original version is shared since 2011. Due to discontinuation of lib toxy, some stuff had to be modified to make Slice//Jockey compatible with Pd-E 0.43. While I was at the job, I took the opportunity to upgrade some effects and overall sound quality. Get SliceJockey2test2.zip from my page: http://www.katjaas.nl/slicejockey/slicejockey.html Please do not hesitate to report bugs if you find any. Katja

cxc library
by Jonathan Wilkes 26 Feb '13

Is cxc part of Pd-extended going forward? Is it currently maintained? If not, I'm going to close the bugs associated with [ascseq] and [ascwave]. -Jonathan

Re: [PD] Changing the defaul language in 0.43
by Hans-Christoph Steiner 25 Feb '13

25 Feb '13

I'm going to CC the list in case anyone else wants to change this value. Tcl looks at HKEY_CURRENT_USER\Control Panel\International\locale in particular. Its a number. This is not Pd-specific, I imagine its used by lots of apps, and perhaps even the system itself. I wouldn't recommend changing it directly, it might mess things up. There should be a way to change the Windows system so that it is set properly in English. If you really just want to force Pd-extended to be in English, the safest route is to delete all the .msg files in \Program Files\pd\po .hc On Feb 20, 2013, at 1:34 AM, rene beekman wrote: > Hans, I'm replyting off-list so we don't burden the list with this. > Attached are screenshots from the registry entries on two of the > machines.

GEMWIN creation / white frame
by William Brent 25 Feb '13

25 Feb '13

Hi all, I need to be able to change the framerate of a gemwin mid-performance, and can't seem to find a way to destroy, set framerate, then create without getting a white frame most of the time on either destruction or creation. Is there a trick to get around this, or something I could change in source and recompile? This is on a Macintosh OS 10.8, GEM 0.93.3. Thanks for any help! William

Midi note handling for monophonic synth
by Joe White 25 Feb '13

25 Feb '13

Hi all, I'm implementing a synth in Pd using midi/notein as an input. One problem I keep coming up against is handling note off messages. This guy's blog post describes the issue - http://kemptonmooney.com/2010/09/pure-data-midi-note-off-solution/ However, I think his solution is not exactly what I'm looking for. The synths I use in Logic have note priority methods and remember all held down notes (or at least 10). I wondering if anyone has managed to implement something like this in Pd or might know where I can find out more about it. ddg.mono from Max ( http://www.cycling74.com/docs/max5/refpages/m4l-ref/ddg.mono.html) looks similar to what I want - but I don't use Max and I don't think I can access the source. Any ideas? Thanks, Joe

OT: Alsa configuration debian squeeze
by Funs Seelen 25 Feb '13

25 Feb '13

Hi list, Sorry for being a little off topic, but I hope to find a solution here. After spending many many hours trying to get the sound on my new machine working I feel I'm getting close, but need a last hint. I hope one of you could help me. After installing pulseaudio and editing ~/.asoundrc over and over again sound worked properly for all applications, except for Pd (ALSA error: Broken pipe). Beside, Jack won't start. I read the recent thread about `Pd and pulseaudio' here but pulseaudio seems not to be the problem in my case. The setup: - sound card: UA25EX (set to card 0 (snd-usb-audio, index=0)); - OS: Debian Squeeze 32-bit; - Alsa: Driver version: 1.0.21, Library version: 1.0.23, Utilities version: 1.0.23 The sound card is compatible with alsa. It has always worked properly under Ubuntu 10.04 on my netbook, with pulseaudio installed, without ~/.asoundrc or /etc/asound.conf or doing any other sound configuration. `aplay' works with pulse and with plughw:0, but not if I select <type hw> and <card 0> in ~/.asoundrc and choose the default. This seems to be a bitrate conversion problem (`available sample format S24-3LE'). I read somewhere that pulse does this conversion automatically, as well as plughw:0, but I assume that Pd doesn't work with pulseaudio. Further, I can't find a way to set this `plughw' (of which I don't know what it actually is or does) as default. Comparing to another system that does work (now Ubuntu 12.04) I figured out that /var/lib/alsa/asound.state on my Ubuntu netbook shows ... state.UA25EX { control.1 { iface MIXER name 'MIDI Input Mode' value 'Light Load' comment { access 'read write' type ENUMERATED count 1 item.0 'High Load' item.1 'Light Load' } } } while my Debian desktop shows ... state.UA25EX { control { } } It is true that I'm not able to set any control in for example `alsamixer' (This sound device does not have any controls) or with `amixer cset'. Editing asound.state manually does not help as it is reset when I `alsactl store'. Does anyone have a clue how I could fix this problem? I prefer not to do a new OS install, at least not Ubuntu 12.04 (Unity). That's why I moved to Debian in the first place. --Funs

Constraining [text3d] within a [rectangle]
by Alexandros Drymonitis 25 Feb '13

25 Feb '13

Hi all, What I have in mind is to put some text in a [rectangle] and start adding characters to it giving it an offset with each character addition. So my question is, how can I make letters invisible when out of [rectangle] (it would be best if they become invisible gradually, as they gradually move outside [rectangle])? More or less like you type a very long URL in the URL field on your browser and the first character of the url address is "moving to the left" getting out of sight when the bar is full and you keep on typing. Thanks
