Re: [PD] [PD-dev] Rewriting a unified phasor / metro object for reading tables
On Wed, 2013-05-08 at 22:00 +0100, Ed Kelly wrote: Hi Lists(s), I'm rewriting phasor~ and unifying it with metro so that a pulse is generated from the boundaries of each ramp - so that bars of music can be read using tabread~ objects with a sample-accurate metro. I'm sure someone will say this can already be done, Yes! but it has to be dropped into the Ninja Jamm patch, so there isn't really time to rewrite the rest of the patch. Frankly, I am pretty sure, just using what Pd provides is too easy to use and likely less time consuming than writing your custom external. (Or I am totally missing the point of this adventure). I don't fully understand the way phasor~ wraps, but I have the object firing out bar numbers correctly. I'm putting clocks in for 16ths and 24ths of the beat, initiated on each wrap. I need to minimise CPU, so what I want to know is this: Does phasor~ always start from 0 and go to 1, i.e. is there always a signal value of 0 at the start of the ramp and a signal value of 1 at the end? As I write this, my common sense tells me it should be yes but I want to make sure. I suppose I should just try it really... No, it's not the case. A [phasor~] ramp virtually starts always at 0 and ends at 1 - true, but most of the time the wrapping point doesn't lie exactly on sample boundaries. This means the sample values around the wrapping point are almost never 1 or 0, respectively. Trying to derive precise timing from the audio domain is a moot exercise anyway, in my opinion. The best you can get from this approach is sample precision and analyzing all samples of a signal is relatively expensive. If you truly care about CPU consumption and a proper design from the start, use [metro] - which is as precise as 32-bit floats can be - and [vline~] - which actually uses the precise timing from [metro] (as opposed to [line~] that doesn't). With this combo [metro]/[vline~] you can rebuild [phasor~] with the additional benefit of giving you more-than-sample-exact bangs at the wrapping points. The only drawback compared to [phasor~] is that the latter allows to control the frequency with a signal and the [metro]/[vline~] based phasor obviously doesn't. I'll be glad to help you build the [phasor~] replacement that has an additional bang outlet, if you need it.

Re: [PD] Pd as sound editor (issue with scrolling a table) ??
Remember that when you redraw an element of an array you actually redraw the _entire_ array in Pd Vanilla. And depending on the array style you may have a separate tk canvas item for each element. why do the iem tab objects work so much better then? maelstorm said that it was incredibly slow using an [until] based counter, but worked smoothly with the iem objects. This was for EXACTLY the same gui, so i'm not really sure if it's a gui redraw issue. Then again, he also said that the iem tabs objects seem to process tables in chunks...so maybe the gui is also only redrawn in those chunk sizes? that would make sense i guess.

[PD] Data structures and click event
Dear list, First of all i'd like to say that i'm very impressed by the potential of data structures in Pd. I've always kind of ignored this feature and it's a pity because it's really worth diving into it. That being said I think that help and example patches are far from sufficient for beginners, and if it wasn't for Chris McCormick's s-abstractions I would have been able to really figure out how to use them (stuff like how to make an entire polygon draggable, how to use GOP with proper scaling, etc.). I m now stuck with a question. How can I identify the element which was just clicked ? I know that [struc] outputs the events, like click, selection and change, but I thought I could identify individual elements by their pointer id. It turns out that I get the same pointer for every element, although I created them sequentially (using [append]). (I guess something must be escaping me about pointers... I've noticed that within the same template, I get different pointers for elements on different y-levels, but the same pointer for all the element on the same y-level regardless of their x.)

And depending on the array style you may have a separate tk canvas item for each element. why do the iem tab objects work so much better then? I haven't looked at the code, but I'd imagine those externals do some array-wide operation then trigger a single redraw of the entire array. For a 100-element array that'd be 100x faster. But if you want the GUI to look modern you want the chunk of samples you're displacing to redraw ASAP. For that Pd (Vanilla) still needs to continually delete and redraw the array as you click-drag the selection. So it's better than the worst of all possible worlds-- using [tabwrite]-- but still extremely inefficient (not to mention it doesn't scale). To be fair, it's unclear how to do this right even with a clean separation of GUI/core. It's unclear what clean means, and it's unclear what this is. To be specific: it's really hard to predict what purpose the user will find for the realtime audio engine when the GUI is also a programming language. For example, you can get all kinds of speedups in a DAW by waiting for the user to release the mouse button when displacing a selection. But if you did that by default for Put menu arrays you'd ruin several of Miller's tutorials, where an immediate connection between visual array change and audio change is vital if inefficient. -Jonathan maelstorm said that it was incredibly slow using an [until] based counter, but worked smoothly with the iem objects.

[PD] pix_buffer loaded event
Hi all, I'm loading a series of images into a pix_buffer using folder_list and [open( messages. I would then like to send a bang event once all the images are loaded. 1) Is there a way to find out when pix_buffer has finished loading an image? Maybe pix_buffer_write has something? 2) Is there a way to know when folder_list has finished outputting all the files? This seemingly easy problem has me scratching my head. The best workaround I can think of at the moment is to just build in a long enough delay before triggering the finished event but that feels like a dirty hack. Thoughts? -martin ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] libpd and Unity
Hi all, I extended Patrick Sebastien's work in libpd-4-unity on Windows and now have it working on OSX and Android. iOS is pending but will happen soon. The whole API hasn't been tested, but basic functionality is in place and works. More info here http://twobigears.com/labs/unity-and-libpd/. Feedback and bug reports are welcome!

Re: [PD] Bugs in Pd-Extended in Ubuntu LTS
Have you tested pd-l2ork? From: Pierre Massat [mailto:pimas...@gmail.com] Sent: Wednesday, March 05, 2014 3:03 PM To: Ivica Bukvic; pd-list Cc: Cyrille Henry; katja Subject: Re: [PD] Bugs in Pd-Extended in Ubuntu LTS Hi, Just a quick follow up on this topic. I have just compiled Miller's latest version (0.45-4), and the bug that's crashing X is still there. This time I managed to reproduce it somehow by creating an empty object to make a subpatch and typing pd m (and bang it crashed). Same behaviour with the same patch in pd-extended 0.43.4. It's super annoying... Cheers, Pierre. 2014-02-25 23:16 GMT+01:00 Ivica Bukvic i...@vt.edu: Once pd-extended removes unnecessary dependency on pd-utils you will. Until then you will need to uninstall one and install the other. On Feb 25, 2014 4:54 PM, Pierre Massat pimas...@gmail.com wrote: Hi, Katja, I will try to check if this is a problem with pulse audio.

Probably you got it from Hans' ppa or from apt.puredata.info? Also, is your Ubuntu 12.04 up-to-date? Your bug description sounds like an intel driver bug in 13.04 or 13.10 that has been discussed a lot on this list. I thought this bug has been fixed for quite a while. i still have some problem. (i'm on 13.10). X can crash specially if i have object that are not created on the patch. c Roman ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] PdParty: name change ideas?
Howdy all, I will begin the process for releasing PdParty on the iOS App Store pretty soon. I was thinking that if I ever want to change the name, I need to do it now. When I started, PdParty was mainly a port of PdDroidParty. Now, it's become something more and I'm thinking of a new name for a different identity. Don't get me wrong, PdParty is already a pretty good name and I may keep it, but I'd like to brainstorm anyway. Any suggestions?

I dislike the i prefix in general but it does seem pretty appropriate in this context so, (i)P(a)d or iPd I prefer Pd Touch for simplicity On Thu, Mar 6, 2014 at 2:35 PM, Dan Wilcox danomat...@gmail.com wrote: Howdy all, I will begin the process for releasing PdParty on the iOS App Store pretty soon.
