How to send an array via OSC to another application?

Hello,

Can anyone please help me with this issue ?
I am looking for a solution for months....

I am trying to send an array to another application by OSC, via the following function in Lemur :


The target and address are good, but the OSC message is not correctly sent out, maybe because it is an array ?
Do you have an idea how I can send the array correctly to the other application.

In SuperCollider, I used to use this syntax with an * to send an array to the other application, and it works :
~serverGRISAdress.sendMsg(*["/spat/serv", 0, (pi*2).rand, (pi/2).rand ]);

Maybe I miss an * in my function ? :
oscout(0, '/spat/serv', {0, MultiBall.x, MultiBall.y});

Hope it is clear.

Many thanks,

Christophe
