Hi guys.
Iam trying to make a binding in the background rack so that I can switch between the next and previous song state with one of the buttons on my M-Audio Keystation 61. (one of the keys with the HUI protocol)
I can switch between the song states if I use the midi learn function and use a key on my keyboard (note on).
That works! But I can’t get the left/right keys working. 
I used the “HUI Switch Decoder” on the input in the option setting in cantabile. And I can also see that the button is working with midi learn… but somehow I get the message that i made an invalid binding!
Any ideas?
Thanks!
Roelli.
