I didn't dig very much much into what OSC bundles were all about but it 
seems to me that it looks more like something to send messages to 
multiple destinations at the same time than to send multiple values to 
only one dest. Somebody correct me if I'm wrong...

I'd have to check that yes, anyway my scope is only a kind of scope, it 
doesn't have to be very very accurate in term of values (-:

I'll bear that in mind as well.
