The event will be sent to the destination as specified in ev->dest.
For events you have just received, the destination is your own
client/port.
Call snd_seq_ev_set_source(ev, ?) to set your source port, and call
snd_seq_ev_set_subs(ev) to specify that the event is to be sent to all
ports subscribed to your port.
