Connecting more than 2 devices

Hello,

I have just downloaded and tested the library. Currently I'm interested in using 3 or 4 devices, but ran into problems if I use more than 2. I've used a slightly modified version of the kinect_basic_multipleDevices example, but here's the output I've got with 3 devices:

and for reference here's the sketch code:

Any tips/hints on how I could get past this issue ?

Also, a bit off topic - does this library expose accelerometer values ?

update to processing 3?

hi there dear Mr. Diewald,
i found your library very interesting and useful, but just didn't found any update for a long time. is it possible to update this to use it with processing 3?
thanks in advance....
