RE: Re: [PD] shortcuts for patching

I agree. Now I've used it for a while I'm seeing one or two minor annoyances and things for my wishlist. Groups would be a useful addition to the pd-gui, along with hide/reveal. I realise groups can get complicated to manage, deleting and adding inclusively/exclusively etc. In the worst case they become a royal PITA. So while I'm thinking about this again here's another way of looking at it.. The issue it addresses is selecting objects in a very cluttered patch. In theoretical best practice you shouldn't ever end up with such cluttered patches because you would subpatch things in a timely and organised fashion. But in practice I tend to build quite a lot before getting to a position where it's time to reconcile large parts of the patch into subpatches and abstractions. What would help is a far easier and smarter way of creating subpatches, which in a way *are* "groups". Two things would help with this. Firstly the process of creating a [pd mysubpatch] object, copying and pasting all elements into it while keeping track of all inlets and outlets could be much improved. Selecting a whole bunch of objects and simply clicking a "make subpatch" that found all terminal signal paths at the boundaries and automatically asigned [inlet/inlet~/outlet/outlet~] would be lovely. Another would be subpatch "aliases" with a "convert to unique copy" procedure - they would behave like in-file abstractions. To be honest I don't entirely get "abstractions". Sure they speed up reuse but they only seem to really help get around the need for tables and delays to be named and the whole rather annoying $0- scoping mess. It's the fact they exist in separate files that makes the headaches. I prefer to use everything in one file to get easier management. In a way abstractions are a danger because changing them can break some other patches. Having anonymous simple delays would go a long way towards simplifying many patches, but that's another topic, however "aliases" would seem to solve a number of issues. They could be combined into the above subpatching procedure. In summary then, what I envisage is as follows: You select some objects You click a "subpatch" option A dialog appears asking for a name (automatically filled with a unique sequential number) The new object is created with automatic inlets/outlets, and why not, wired in-situ in its current place so it can be immediately tested. You select a subpatch and copy - a dialog asks whether you want a unique or aliased copy. An alias is identical to an abstraction with all scoping rules satisfied, but it only exists in the current file, if you edit one instance in the patch all others change too. that's my loose change on the subject, cheers, Andy >on the vector theme, i think a group function would be >handy (group several objects then select them with one >click) > >all the best > >adam > >Send instant messages to your online friends http://uk.messenger.yahoo.com > >_______________________________________________ >PD-list(a)iem.at mailing list >UNSUBSCRIBE and account-management -> >http://lists.puredata.info/listinfo/pd-list

Gem: xorg: Dual head acceleration on Radeon 9200 Pro
by Alexandre Quessy 08 Jun '06

08 Jun '06

Hi all, Below is my xorg.conf file. I just set a Ubuntu box to work with two monitors using MergedFB so that we can obtain 3D acceleration on both monitors. In a Dell tower with an ATI Radeon 9200 Pro. The result I got is that the Gem window only renders on the first screen, and not at all on the second. Do you guys know a turnaround so that I can get hardware acceleration on both heads ?

triggering a linear ramp with a signal
by Micha Thies 07 Jun '06

07 Jun '06

dear list members, i am currently porting some max granular patch of mine to pd, where one object gives me some trouble. i am now looking for the function in pd of triggering a linear ramp with a audio signal (resp. click), with the ability of controlling the speed of the ramp also with a signal. i know that there is an rampsmooth port, but this one takes only messages for the rampspeed. anyone can help? btw., platform is windows and linux... thanks in advance, micha

usb tv capture card on linux
by Igor Medeiros 07 Jun '06

07 Jun '06

i want to buy a usb device that can capture tv and can feed pd with live video for image processing with pd/pdp/pidip/pdp-freeframe, maybe gem. i am planning to do it on linux. can these externals works with 640x480? gem probably yes, but i don't know about pdp/pidip/pdp-freeeframe. any suggestions? thx in advance igor -- _________________ www.mediasana.org

pd crashes when using expr
by Tina Shah 07 Jun '06

07 Jun '06

hi list, i'm trying to use the expr object in my little app to figure out the range of incoming h values (hsv) - i.e.- if ($f1 > 0 && $f1 < 0.05, 1, 0); right now i have 9 of these types of if statements. when running the program things don't work properly. pd crashes when i go to edit the expr part or when i destroy the gem window. also while running the app i get these errors: error: expr: ex_eval: unexpected type 0 expr: bang: unrecognized result 881328160 the file attached is the file i'm working with. please let me know if anyone has any ideas of what might be wrong. i'm using windows xp, pd .39-2 and gem .90. thanks! -tina

trouble with data structures
by Julian Peterson 07 Jun '06

07 Jun '06

I'm writing my first piece that will take advantage of data structures in PD, and I've stumbled upon an error that I do not understand. I have two structures drawn in the same subpatch. One is a sequence of notes, the other is a playhead. The sequencer was working fine until I added the playhead. Now whenever I try to get data from the sequencer (getsize, get) I receive the following error: error: getsize pd-instr1: got wrong template (pd-playhead) My patch is attached below. Is it not possible (or not advisable) for two structures to draw to the same subpatch? (The csoundapi~ object is used to generate the sound for this patch, but is unnecessary for duplicating the issue...) Thanks in advance for any advice... Julian Peterson

<pre>that sounds good, i think there are some moves afoot to give subpatches some abstraction like properties. one refinement i'd suggest (to make patching faster) is to have unique or aliased as a default (which could be changed with a preferences file) so that copies can be pasted in without a dialogue box appearing, and then an option to convert from one type to another (if several subpatches could be selected and have their type changed at once this would keep editing fast) - kind of like make ghost copy in cubase >You select a subpatch and copy - a dialog asks whether you want >a unique or aliased copy.
