Hi Tony,

just put it on Github- hope I did everything right :) https://github.com/fbpsound/pip_abstractions . Will be working on the help patches this WE.

Thanks again for your input!

Cheers,

Filippo

Hello list,

I've collected and cleaned up a few patches that I've been using a lot while making game audio with PD (mainly for Android, using libpd, Unity and Kalimba) and wanted to make them available to everyone.
Giving a tiny bit back since I've received so much help and advice from the PD community!

I'm mainly trying to cover what a PD beginner/game audio composer would need in order to start building a PD-based audio engine for a video game. Threw in some mixer abstractions, some stuff for interactive music, a state-based drum machine and so on.

As I said it's super basic, but it might just be less intimidating for someone who's just interested in the game audio potential of PD to have these basic blocks handy.

Let me know if there is anything that can/should/must be improved in order for it to be of any use! I'd like to make help patches for the abstraction as well, but am not sure if they really need them since most of them are very simple. What do you think?


Cheers,


Filippo

Subject: Re: [PD] Wich licence?

Right, I put GPL license, I think it is the best for this project. I
uploaded it here:


You can see MEH-SYSTEM on stage and with full success, here:

Thanks everybody!

Haha! Good point!

Thanks everybody for the answers. I took a look to Matt Davey's DIY2
effects and he put no license txt file on its folder. Maelstorm mmb
libraries have no license too...

My patch is for everyone who wants to use it or learn with it. If
someone finally uses MEH-SYSTEM or a modified version of it in stage or
for a video or whatever... I "would like" to know it... only that!

Maybe I leave it as is. Saying nothing about license...

Skim the Wikipedia pages for GPL and 3-clause BSD, choose the one you
prefer, and then you're done.

Otherwise you create potential work for anyone who may have a use for
your software to figure out what the terms of use and distribution
are. It's probably not a big deal for a particular piece of software,
and there are plenty of Pd patches out there that don't specify
anything. But when you take, say, everything that exists on Github,
the lack of licenses probably leads to busywork that eats up
measurable amounts of time and effort.

------------------------------
Hello,
having no licence is probably not a good idea, as it's like enforcing
the default copyright rules that basically give no rights at all ...
(lots of code are practically not legaly usable on github for that
reason f.ex.)
the best would be IMHO to put it in (L)GPL and gently ask to downloaders
to report use as a courtesy on the download page...
have a good day,

Ol.

IMO a separation between GUI and core could/would include position, e.g. objects have their connections mapped by an index, GUI assigns the index to the object based on position.  This would allow for some much more sophisticated GUI's, such as 3d, or even a more human-readable text version (json has been mentioned).

luckily the work on the GUI will most likely happen in git, which
gives you infinite undo.

The question is whether a highly capable dev who isn't already
entrenched in Pd development would see participation as worthwhile or a
waste of time.

What I'm saying is that without a clear plan, no sane developer is going
to undertake the work of adding infinite undo, various GUI improvements,
or anything else that can't ship as an external.

But yes, technically you can use Git to do yet another GUI rewrite if
you wish.

You run into problems when you want to get decent GUI interaction _and_ expect to deliver audio to the soundcard in realtime.

Actually even in 2d without audio the problems manifest themselves pretty quickly.  For example: open the svg tiger inside Inkscape and move it around.  Notice the clever trick-- the image is broken into tiles and moved starting with the pieces closest to the mouse.  Since the user's eye focuses on the mouse pointer, the interaction looks snappy even though it may take half a second or more to finish moving the tile furthest from the pointer.

When you add realtime audio the options are either to err on the side of sluggishness or to be responsive and risk dropouts.  If you want it to be responsive in both video and audio then you have to start doing some serious optimizations based on what you think the user cases are for the software.  For example, the Inkscape trick is perfect for creating and manipulating vector graphics, but it would be terrible for a 2d animation environment where you'd presumably want the tiger to move as a single unit.

However, many of Pd's current problems don't have a lot to do with that.  Tk is pretty good at being sluggish and avoiding dropouts when it doesn't have idle time to do graphics updates.  In fact I can move around an svg tiger on a canvas without interrupting the "test audio" patch.  Most dropouts related to the GUI have to do with what amounts to a DDOS attack from the core to the GUI.  When you flood tcl with data from the socket it can't really do anything else but spend time receiving it.  When you add that to whatever Pd core is doing to generate all those messages in the first place, you probably won't have any time left over for delivering audio.

Other toolkits are certainly more efficient than Tk.  But if you're dragging an antialiased wire from the top left of the window to the bottom-right, the toolkit needs time to do those redraws.

Finally, I'm not really sure how Open-GL and hardware acceleration plays into all this. For example, Qt Graphics View docs have a note about accelerated graphics possibly adding a performance hit and possibly more latency, but it's only in the context of hardware that doesn't do floating point computations efficiently.  I played around with Kivy a bit, which is hardware accelerated but honestly didn't see much of an improvement in cpu usage over comparable stuff in Tkpath.
