Is it possible to make a ZIP version that just run? Like Pd`s Zip Version.

Probably after that the best thing is to drop XP support, and just use a 32-bit binary of the most recent version of nw.js for all Windows versions. > doesn't it make more sense to have a 64 bit versions for windows, and not dropping XP support? One of the most amazing thing about Pd is that it can run anywhere, I'm sure someone will be bummed out for not being able to install in on XP I can wait a little longer-- at most until nw.js bumps the LTS version. -Jonathan > cheers

iemnet/tcpserver too sloooooow
by rolfm＠dds.nl 12 Jan '17

12 Jan '17

i'm sending data using tcpserver & tcpclient over wifi with a router in a local network. testing with different combinations of 3 systems: laptop W10 Vanilla 0.47-1, Pi-3 Raspbian Jessie Vanilla 0.47-1, MacBook OSX 10.5.8 Pdext 43.4. transfer of the same data takes (with some variations): W10 -> Pi 150 secs Mac -> Pi 170 Mac -> W10 200 pi -> W10 210 Pi -> Mac 23 W10 -> Mac 23 W10 with Pd-ext -> Pi 150 to me it looks like the tcpserver is the culprit. using [netsend] & [netreceive] gives Pi -> W10 17 secs W10-> Pi 27 the data transfer is as follows: the source patch sends 6 bytes and then waits until a single byte comes back that signals the next 6 bytes can be sent. in total 3538 data recs of 6 bytes are sent. what could be the reason for this behaviour? a bug? rolf

Netcasts: msp "Pd worldwide" (Jan 15), "Worldwide sounds of Pd" (Jan 16) -- http://newblankets.org
by Joe Deken 12 Jan '17

12 Jan '17

I hope the Subject: header is informative enough that you may stop reading without loss, if you don't need further details. If you do have interest in more details, however: - New Blankets *Benevolent Netcasts* are designed to make people aware of free/open community-building activities. The point is that listeners may pitch in and give of their own time and effort and/or cash to these "worthy causes." 1 - Some NB netcasts are for the benefit of "registered non-profit" organizations; New Blankets simply passes the money along to such organizations. 2 - Some netcasts benefit community groups who are not registered non-profit charities. New Blankets keeps those donated funds internally, but separately accounted for, so that the community group may direct how New Blankets will expend those resources on their behalf. 3 - Some NB netcasts are to raise "blue sky" future-funds that New Blankets would like to build up. These funds will be used (as just one example among many) for all the activities and ways that New Blankets has helped the Puredata Community in the past. In addition, New Blankets will launch a "mini grants" program in 2017 so that Pd-folks (and others) may apply to NB for a bit of equipment, travel-support or what-have-you -- within the limits of New Blankets' limited budget and proceeds from these fledgling-fundraising activities of ours. Thanks for listening. PS If you want to hear other archived Benevolent Netcast shows (e.g. with Julian and/or Katja&Fred Jan) just send me an e-mail (joe_deken(a)newblankets.org) and I'll point you to the right spot in the archive. All disclaimers apply about the netcasts; we're winging-it, and learning as we go. Thanks to ALL NETCAST GUESTS for their patience and good humor; let me know directly if you'd like to be a guest on the program yourself.

Rotary controllers for finetuning data?
by Esa Ruoho 10 Jan '17

10 Jan '17

Hi, I've been scouring the net trying to figure out how to utilize a rotary knob I have on my Faderfox UC4. I have gotten it to work like this: twist-left = 127 twist-right = 1. I'm trying to use it so that one is +1 and one is -1, endlessly, and to set it to a low enough amount to be able to control the pitch of a phasor~ in my patch. So Instead of it being +1, it'd be like +0.0001 and -0.0001, for instance. and this would affect a number that has already been stored in a.. float, maybe? I got this far, to separate the data: ctlin 53 | == 127] | moses 1] | - 1( | print and ctlin 53 | == 1] | moses 1] | + 1( | print what I'm getting is "print: + 1" or "print: - 1". But I'm vague on how to first use a 0-127 knob to set the main value, then affect that stored value (inside a f, I guess?) with the +1/-1 so that it gets changed, and is output to the phasor~. Any ideas how to go about it? -- --- http://twitter.com/esaruoho // http://lackluster.bandcamp.com // +358403703659 // skype:esajuhaniruoho // http://esaruoho.tumblr.com/ // iMessage: esaruoho(a)gmail.com //

Upgrading from Pd-extended to 47-0-64bits OSX
by jma＠jeanmarie-adrien.net 10 Jan '17

10 Jan '17

Hello This is a attempt to migrate from pd-extended to more updated versions for everyday use : means im trying to make my own libraries (for the first time in 15 years) I've discovered the ‘Find Externals’ lever in the main menu, and it works for zexy, iemmatrix (so far) but i could not make it work for cyclone or maxlib means (cyclone) and (maxlib) folders are downloaded to /Library/Pd/, just as iemmatfrix or zexy but when launching pd it says "can’t load library" in all cases i do download the (Darwin-x86_64-32)(sources)-externals. Anything to ‘make’ ? Sorry to post this obvious question, looked for a while hints on internet and archives without success tks JmA

Re: [PD] Nonlocal shared symbol ?
by Jérôme Abel 10 Jan '17

10 Jan '17

> a [text] (and get its first line from your abs) Inside the main patch, I use [text] to read constant values from a textfile. Then I could store them in containers like [symbol], [float], [list] in each abstractions but it seems (for me) not flexible. It does not allow to open a patch or an abstraction which needs thoses values. I can reload the textfile when the patch is opened but I don't like this design : when I reload the textfile I trigger values into the 2 patches. My way now is a [text] loader of the same textfile into my main patches, called once at the startup. The [pv] object from cyclone is a good choice, thanks for the tip. It just needs to be created in a parent level. > But if you only have to get its constant value (and not to modify it) then > you could just call a shared abstraction in your abs, that would just send > the symbol to an outlet? Do you mean one [text] loader into each abstractions ? -- Jérôme Abel http://jeromeabel.net http://reso-nance.org

declares in a new (sub)window
by rolfm＠dds.nl 10 Jan '17

10 Jan '17

hi a new window opened in an existing patch becomes completely part of the overall name-space. but the declares are NOT applied. why, is it by design? it seems illogical, especially now the declares rule from the top-level patch. rolf
