I'd like to help, but I am not going to have time. I'll be on tour starting Sat. for two months. Any flext people want to try to get flext builds in Pd-extended? There could also be a Pd-devel-extended without too much work. Jamie had talked about it in the past. .hc On Apr 11, 2006, at 5:24 AM, Thomas Grill wrote: > > Am 11.04.2006 um 00:52 schrieb Hans-Christoph Steiner: > >> >> All are fresh downloads of the binaries from your site.

inlet and inlet~
by Matt Barber 18 Jun '08

18 Jun '08

Hello, Is there a way to make an abstraction that has one inlet that takes both signal and control messages (like osc~, e.g., or fiddle~ which gets audio and setting info, etc.)? It's part of the API for objects; it seems to me there ought to be a way to do this with abstractions as well. I'm envisioning an inlet object that splits signal and control into two outlets which can be parsed from there. Something that uses the signal and control values to do the same thing (as in osc~) might be difficult to implement in an abstraction, but having signal and optional settings messages go to the same inlet would add to the abstraction-as-object nature of PD... does it exist? Thanks, Matt

Lua and PD (update)
by Mike McGonagle 18 Jun '08

18 Jun '08

Hi, A few months ago, I inquired about what sorts of "sharing" can be done between PD and Lua. One Idea I have for working with Lua and PD was to create the interface in PD, and use PD variables to pass the data to the Lua script running, and I was just wondering if this is now possible? 1. Lua access to PD variables 2. Lua access to PD tables Another idea that I had was, instead, have my Lua script create a bunch of 'receive' objects, and just have the PD interface send the data to that receiver, rather than use a variable. I am just wondering how each of these approaches would function, as I am going to be creating between 20 and 60 variable/receive connections within a single script. Also, is there any sort of "coding standard" that has been established in pdlua? When I started to learn Lua, I wasn't using PD, and since I started with PD, I noticed that the Object system used by pdlua was different from what I had done. I have since gone back and reworked some of my things so they are more like what pdlua uses. Just curious about this, as I don't want to find some "gotcha" a few months from now.

Pd-extended PPC autobuild & Jack OSX
by Si Mills 16 Jun '08

16 Jun '08

I noticed the other day that when selecting to run in Jack mode (with Jack booted) the system becomes unusably sluggish. This happens in the PPC version of 0.40.3 -extended that I downloaded the other day from Autobuild and Jack osx 0.77. I haven't tried one of the latest builds. I'm adding this to the bug tracker thanks

I cc'ed the list since I think this is of general interest, also, other people can contribute there as well.

Getting Sysex output to work on Linux
by PSPunch 06 Jun '08

06 Jun '08

Hi, I am hoping someone can give me advise on getting my Ubuntu box to send sysex message over MIDI. Some questions.. 1) What is the proper format for messages to go into [midiout] or [sysexout]? Do I make a list of numbers such as [247 NN .. .. .. NN 240< or do I need to serialize them as [sysexin] receives each byte as individual messages? 2) Previous posts on the same topic were a bit too vague for me to catch up with. Although I use Debian & Ubuntu daily, unfortunately I am not fluent in developing practices enough to design my own workarounds (at least not yet). The closest I could get was the understanding that there is no method to get Sysex output to work other than patching Pd so a different kind of function in ALSA-API will be used. (also that the current releases have a 20 byte limit. This is probably not my case though) If current pd-extended (which I am comfortable with, either stable or testing) needs patching in order for midiout to work, I would highly appreciate specific procedures on how to get it going, hopefully on a fresh installation of Ubuntu 8.04 or 7.10. Any type of help appreciated. Thanks. -- David Shimamoto

processing images with GEM?
by matteo sisti sette 05 Jun '08

05 Jun '08

Hi, I have to perform some very very simple computer-vision tasks (such as motion detection) on image data captured by a camera, and I was considering/evaluating the possibility of using GEM to do that. It would involve basically computing the difference between two frames, background subtraction, masking an image with another one, computing the avarage value over a rectangular portion of the image, and this kind of things. I'm a bit lost, since I guess there are probably facilities to do such things in GEM, but I don't know where to look for. 1) Are there some pix_ objects to do these kinds of operations in a reasonably efficient way? 2) Is it possible at all to use the openGL wrappers to do such calculations in the GPU rather than CPU? Where may I find examples of that? 3) Are there some objects that already implement the latter approach and offer basic functions at a slightly higher level, such as frame-difference on a texture buffer? If anyone can point me to any documentation/examples/tutorials specific to this kind of things, I'll be very grateful. Or maybe this is not the kind of things GEM is suitable for? Should I forget about it and have a look at other platforms? Thanks, m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

netpd broken?
by Max Neupert 01 Jun '08

01 Jun '08

servus roman, list, i wanted to demonstrate netpd today here in melbourne and failed. on a intel mac os x 10.5: with a fresh pd-extended 0.4xx and downloaded netpd.zip i can open _chat.pd. then when i click on creator additionally a blank patch pops up called "pd cr.singletons" the console spills out: netclient ... couldn't create error: inlet: expected '' but got 'connect' ... you might be able to track this down from the Find menu. error: pd-cr.singletons: no such object i can reproduce the same on my own machine os x 10.4 ppc. also there is a small documentation bug: it reads: START netpd - start pd and open _chat.pd - click the 'settings'-bang - set your name - click the 'save and close'-bang - talk to other netpd-people and start a session there is no 'settings"-bang, it's called 'pref' and doesn't look like a bang. inside is a 'save&close' button. suggestion: - hit the 'pref'-button to set your preferences - set your name - hit 'save&close' ciao, max
