Hi Enrike,
Im not sure of your setup but should you have access to a gps signal you could use it to sync all devices... I think.
Good luck!

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!
