As I see it we kind of have to stick with that for now, unless we want to force everyone to set up their systems exactly the same and to install all externals. And with everyone I'm not only talking about users, but also about developers (i.e. the author of bp2~.pd which doesn't use import or declare or a directory prefix in front of [filter~]) And it's not only about externals, it's also about differences like the setable sends, [list length] etc. in 0.40 which are all missing in the latest stable pd-extended. If you want to use these, you have to ask the user to install a more recent version of Pd anyway in a README. But actually with pd-extended it's not hard to make most externals available right from the start. In fact, most libraries like zexy or iemlib or so are all activated in pd-extended, at least the .pdsettings of RC2 has a lot of stuff already in it, so there's not much user interaction involved. Regarding the missing bp2~: I think, this abstraction is more or less gone and replaced by bpq2~.pd and bpw2~.pd. At least these are included in pd-extended. Probably your TR808 will clap correctly for every pd-extended user if you use these names instead.

Keep an old copy of the file, then make your edits, then run this:

Re: [PD] GEM and chromium

I didn't see a compile option that allowed me to disable these frame buffer commands, so I added this: #undef GL_EXT_framebuffer_object to src/Controls/gemframebuffer.cpp after the includes. and now gem works via chromium. Maybe the Gem developers could add [or suggest one that already exists] a compile time option to disable these commands, so that others might be able to use chromium with gem as well. -Alex btw, I've sent this info to the GEM list as well but figured it might be useful for some people on here as well.

yup, i used the pduino firmware, though not the arduino abstraction. for
my purpose - i wanted to work with a timegrid and a stepsequencer, where
sometimes more than solenoid were triggered at the same time - i did not
use the [arduino] abstraction in order to send only message (for example
'24' to trigger solenoid 4 and 5) instead of two messages ('16' and
'8').
it worked quite well, but there is still room for improvements (i mean
not for the pduino-project, but when arduino is used to trigger
solenoids). it turned out that the length of the 'on' period is very
sensible. a bit of jitter in that period causes sometimes the solenoids
to not reach the object or to hit it too strongly. since pd controls
both, the on and the off time, this period is not very constant. when i
find time to learn the arduino language, i might write my own firmware,
where i can send the period as a second value, so that the arduino
itself controls the timing and not pd.

That's Roman of netpd fame (you can see netpd on the screen). I
forgot whether Pduino was used for that or not. I would like to
know. A student here at Poly in Brooklyn used Maxduino (the Max/MSP
port by Marius Schebella) but had a lot of trouble with timing. I
would like to see whether arduino USB can do tight timing like in
that video.
yup, i used the pduino firmware, though not the arduino
abstraction. for
my purpose - i wanted to work with a timegrid and a stepsequencer,
where
sometimes more than solenoid were triggered at the same time - i
did not
use the [arduino] abstraction in order to send only message (for
example
'24' to trigger solenoid 4 and 5) instead of two messages ('16' and
'8').
Seems like Pduino should have a message to send the whole button
array at once, since that's what's going on underneath. Something
like [digitalPort 29730(, where 29730 would be the bitmask of the
digital pins. Or it could directly mirror the underlying firmata
message like this: [digitalPorts 116 42( with two sets of 7-bits.
it worked quite well, but there is still room for improvements (i mean
not for the pduino-project, but when arduino is used to trigger
solenoids). it turned out that the length of the 'on' period is very
sensible. a bit of jitter in that period causes sometimes the
solenoids
to not reach the object or to hit it too strongly. since pd controls
both, the on and the off time, this period is not very constant.
when i
find time to learn the arduino language, i might write my own
firmware,
where i can send the period as a second value, so that the arduino
itself controls the timing and not pd.
I don't think that the timing problem is related to Pd but rather the
USB-serial drivers. Writing your own firmware to trigger events will
work if you send the timing, which would then be handled by the
arduino, therefore eliminating the USB-serial issue.
Instead, I think we'd all be better off if we can work together to
get Pduino working for this kind of application. This is exactly the
kind of stuff I had in mind when I wrote Pduino. I am open to
suggestions and patches.

Re: [PD] DSP abstractions [was: netpd ...]
This is a bit off the current thread, but is still relevant to the subject. I like the discussion about DSP-abs, but in my opinion, we should not forget also the CTRL-abs that netpd provides. I think that the sequencer objects in there are quite efficient and usable from a newbie point of view, and whereas getting crazy bleeps and bloops out of Pd can be done quickly with a help file or two, creating a decent sequence is a little more removed/frustrating. So carry on guys, I am enjoying following this thread even though I haven't said much.

[PD] Active stereo Gem (Crystal Eyes)
Hi, (I originally sent this to the GEM-dev list but i figure others on
here might be interested in this information)
I've added the ability to do active [crystal glasses] stereo in gem [using the
X version] and am attaching the diff. If you have a stereo enabled video card
and a display that can support it this modification will open a stereo window by
default and then you will be able to use this additional stereo mode [3]. If
you don't use this stereo mode there should be no change in what you see, if
your videocard doesn't support [or isn't set up for] active stereo then you
won't be able to use this stereo mode as you won't have a stereo window that
you're drawing to.
I've only added stereo windows for the X version of Gem but it really shouldn't
be hard to get it working for Windows or Mac, all that needs to be done is to
open a stereo window by default if it is supported by the graphics card.
I've attached a diff to the most recent CVS, hopefully this will be useful for
other folks.

Instead, I think we'd all be better off if we can work together to get Pduino working for this kind of application. This is exactly the kind of stuff I had in mind when I wrote Pduino. I am open to suggestions and patches. i didn't write my own piece of code yet. i am an absolute beginner in this, so i think it takes a while until i am able to contribute. but it would be nice, if pduino would support various ways of controlling the outs. i didn't know, that this could be possible with only one firmware. roman ___ Der frühe Vogel fängt den Wurm.

Re: [PD] cross-correlation in pd ?
Hi Tania, aubio is quite easy, provided you have libsamplerate, libsndfile and fftw3 installed. It is pretty essential that you instal pkgconfig as well, since some libraries rely on that to send information as to where they all reside on the hard disk for compilation. So, aubio in steps: First, URLs: pkgconfig: http://pkg-config.freedesktop.org/wiki/ libsndfile: www.mega-nerd.com/libsndfile/ libsamplerate: www.mega-nerd.com/SRC/ fftw: http://www.fftw.org/ and aubio-0.3.2.tar.gz unpack them all in the same directory. Put the attached script in the directory all the other packages are in then... Then you can use this script to compile them all (see attachment). You will need to be logged in as the administrator, and know the administrator password. You must open Applications - Utilities - Terminal # then type cd /path/to/where-you-unpacked-the-files/ sudo chmod 744 instaubio.sh password ./instaubio.sh have a look at the script using textedit - it uses fairly common unix stuff, and I'm sure you could work it out yourself, or you know it. Maybe I saved you some time! ;-D but aubio needs things in the right order. PS I know Paul is writing up his thesis right now, so maybe he's a little quiet!

No more news on where you might find the externs im afraid, but in case you do get the iem table one working [tabsend~] I suggested would be useless because two of them would seem to be asynchronous and make nonsense of your correlation (is that right?).

Re: [PD] cross-correlation in pd ?
Mathieu's right here... It can be done with abstractions. I'm not sure that mine are all correct, but I've used this technique a couple times without making complete abstractions for it... Here's an abstraction for computing a symmetric cross-covariance, this way. It outputs the cross-covariance, xcov(k)=sum(i=-32,...,31; s1(i+k)*s2(i)) It's still pretty ugly, and the details of the math confuse me a bit. I'm still working on the one-sided cross covariance function for delays, like from [0,63] instead of [-32,31] This one works within block sizes of 64, by using an [block~ 128 2] . It is formatted very tricky using lrshift, but I think you will see that it's continuous. The test patch uses zexy for z~. If you want to compute xcov on larger block sizes, just change all the numbers according to the size you need. Do you think I've got it right? Should the output be reversed? This abstraction also could be improved to make running calculations of cross-correlation, which add up the variance in s1 and s2 and normalize the output. Jamie Bullock has cc~ in his flib collection. It computes cross correlation in the time domain, and cross-covariance using the freq. domain. I worked on it a while back...but have been lazy about trying to change the cross-covariance into a cross-correlation. Sorry, Jamie.
