Are you opening with the following message?

[ listen 57120 224.0.0.1 <
|
[ netreceive -u -b]

The address is within the multicast range, so it needs to be given to netreceive in addition to the port.

But with [netreceive -u -b 57120] (or any other options to netreceive) 
no data comes into Pd. Does anyone have any suggestion on how to receive 
the data?
