hi all

We need a chronometer that runs in sync in multiple devices at the same
time. Target platform is android, and if possible iOS as well. We are
thinking also that it would be great to have some sort of metronome
running together with the chronometer (we have trained musicians
together with non trained musicians in the ensemble).

So far we have been using http://chronograph.io/ so far but it is not
100% reliable, we had a few issues last performance (one device was ~1
sec behind the others, and often during rehearsals we had problems with
the start signal not being sent at all).

I am considering the possibility of implementing this functionality in
PD using PDdroidparty and OSC. Because we dont like the tools we have
found online. We found some nice metronomes but the only one that seems
to sync is only iOS. And we do need the chronometer (in fact priority n1
is the chronometer right now). I thought maybe someone can point into
some existing alternative before I try to reinvent the wheel.

One of the biggest issues I foresee is to find an easy and quick way for
the master device to find out the available slaves in the network. I
would not like to have to, one by one, find and then type the IPs of
each single device in the master device, although the master could be a
laptop running PD and that would make it easier to type them...

thanks in advance for any feedback

hi,

i am trying to make a patch involving a live camera on PD 0.49.0 (64bit)
with Gem 0.94_pre1 (64bit) on a windows 7/64bit machine.

so far everything works alright, but i can't set the camera resolution !

unfortunately the default resolution is 160x120, which is pretty
useless. so far i found no way to change that resolution, the "dimen"
message does nothing and setting width/height via the props method also
doesn't work.

now here's another strange thing: with PD 0.48 and Gem 0.93 (both
32bit), when i opened the camera dialog (with the "dialog" message to
[pix_video]), 2 windows opened: 1 for the camera driver settings
(brightness, contrast, exposure etc.) and 1 for the resolution.

so with the fomer (32bit) version of Gem i COULD set the camera
resolution to the desired dimension.

however, sending "dialog" to [pix_video] in the 64bit version described
above, i only get 1 window, the one with the driver properties (which
btw i can also set via the "props" method)

can anybody help me in this regard ? is there a workaround to manually
set the camera's resolution ?

unfortunately i need the 64bit version of Gem because of the amount of
RAM i need (i record video frames over some peroid of time, and the
32bit version is limited for my needs). plus the 32bit version doesn't
work (i already reported that to the list)

thanks for any hints

best

oliver

Hi Enrike,

you'll probably find that syncing many devices together (especially via a
wifi network) is a rather difficult task.
Many parameters can make it complicated, above all network latency and
device latency. Network latency is often quite variable and unpredictable,
and the same goes for audio latency on Android.

That said, it seems that the best solution currently is Ableton Link (
https://www.ableton.com/en/link/), which is a GPL cross-platform library
and protocol.
It is implemented to Pd through the [abl_link~] object (available from
Deken for most platforms).

In some case where [abl_link~] wouldn't work (I had crashes on a
raspberryPi), you can use Carabiner which provides a network socket to Link:
https://github.com/Deep-Symmetry/carabiner

good luck!

Greetings fellow Pd enthusiasts,

As some of you may be already aware, ast year the Purr-Data (a.k.a.
Pd-L2Ork v2) was adapted to support native 64-bit operations. We are
pleased to report that Purr-Data was once again selected this year as one
of the GSoC projects. This means more opportunities to engage and help
further the platform. Ideas for this year are plentiful, ranging from core
infrastructure (C) development to patching and front-end development,
including porting Pd-L2Ork's K12 learning module that has seen its
utilization in dozens of Maker camps over the past 7 years.

If interested, please contact Jonathan and/or me to explore potential
projects and to discuss the next steps in the application process.

Best,

Ico
