I manage to send data from Processing to Arduino. I manage to send data from Arduino to Max.

Also, If I change datas manually in Max and I reboot (by pushing the reset button of the Arduino Uno), datas of the setup (of the Arduino program) go well in their channel.

Then when I start Processing, datas are exactly send at good places in Max. At the beginning nevertheless.

A few second after, I read theses bugs in a Max console.

In this exemple when I stopped Processing, you can see datas routed with A, B, C, D, E not match with Max

There is an ''offset'' in the reception of data which should all happen in their channel A, B, C, D, E. The datas arrives randomly in A, B, C, D, whereas if I send 'only't datas from Arduino to Max, datas arrive in their matched channel.

Thank you, I wish I'm just momentany blind and you'll see the light to make this stuff works ;)

I give the patch made Max 7 and the two code made with Arduino IDE and Processing.
