I figured, but if you actually remove Gem, somehow, sound stops, so it is
part of the implementation somehow I guess.

yeah, doesn't seem so, but it's gotta be related somehow, right?

I guess it depends on each case, sometimes (I actually think most of the
times) I do offer something different (with more features) and better
resolved, other times it's something simple that doesn't make much sense to
require a dependency, but nowadays, with plugdata, there's always an excuse
or actual requirement to add something (and I am thinking now of the time
and date alternatives that I didn't need or want myself, but someone
requested for plugdata).

Re: [PD] time/date

[Dan Wilcox]

I also use the sexy [time] object. It is actually the only reason I have zexy 
installed as I try to be as vanilla-only as possible due to working with libpd.

I agree that at this point it would be nice to have something like date & time 
built into vanilla... however the objects exist and are easy to install/use on 
desktop.

not at all.
Gem just does the visualiation, but the actual physical model runs

[pdp_scan~] will scan an image along a trajectory, and convert the

it's not really what "scanned synthesis" is referred to in the wikipedia

Running this in Extended now, it looks amazing. Do we really need Gem
though? I figure it is just for displaying the array which is also a model
of a string, right? Perhaps one could use a Data Structure array instead?
Or just nothing at all to just focus on the sound. By the way, how do we
set the frequency in your example? It seems fixed.

As for pdp, it seems it tries to use the webcam or video sources and I
don't understand why.

In fact I know nothing about scanned synthesis and I just ran into it by
accident when reading about vector synthesis in wikipedia, and I even read
the original paper but I couldn't figure it out much yet.

It sounds at first some kinda of wavetable synthesis but it is clearly
physical modeling, right?

Would love to dig more in it and provide an external myself but it looks
quite complex...

thanks

Oh yeah, I now remember we gotta install XQuartz for X11 and Extended! It
works :)

Re: [PD] time/date

[adam johnson]

On linux and probably OSX and bsd you can get to time and date from
/proc/driver/rtc, use [file copy] to copy /proc/drive/rtc to a temp file
and then read that temp file into [text], then just grab the needed fields
from the [text]. This will work on most any linux and if it does not work
on OSX/BSD they will have this somewhere in /proc/ or /sys/, been too long
since I have used either of them but I think they have /proc/driver/rtc, no
clue about Windows.

I looked for this for YEARS and have been away from PD for a little while,
but was always something that seemed to have never been implemented in
vanilla.

Dear group,
Is there any solution for getting the system time-date in pure data vanilla? I 
would like to use my quick recording abstraction without worrying about file 
name and I know it could be done by using [savestate] and incremental numbering 
system, but I think it could be much more elegant to just use the time-date 
stamp as file name.

you need X11 for pdp. iirc, on macOS you can install it via XQuartz.

which kind of explains why pdp worked with older versions of OSX, but 
not with current macOS.





Purr Data can't load it either.


obviously, you still need X11.

as expected.

where all externals lived in the days of yore: the sourceforge SVN


a read-only git repository can be found at 




the code hasn't been touched in 12 years, it probably won't compile on

Debian still provides pdp binaries, so there's a couple of patches that

these patches might be very Debian specific (solving problems that only
