Perfect! The only thing that I've noticed is that everytime I change the 
channel argument, in the subpatch I've that $0=$0+1
I think because a new dynamic patch is created... but I think that 
should not be an issue... at least in the real use case where the 
channel is selected once at the "init"

Thanks, now it's perfectly clear the meaning of the message block... 
It's quite easy, but I was not familiar with dynamic patching! :)

True, but I've already modified that part of the patch in order to 
select a default channel if no argument is supplyed!

Thank you Patrice! :)
