Thank you very much , Hans ! :)
Earlier you thought about a permissions problem, and you were right. I
found that one of my groups (operator) was able to read the /dev/umidi0.0 ,
but had no write permission. So, it explains the "not bidirection"
What I did was add a new entry to /etc/devfs.conf
perm umidi0.0 0660
