bug:Scale device stops working

[abletoff]

Hi,
after using Scale device (the same ctrl+dragged to different tracks if it means something) after some time the device stopped working at all. Changing values did not do anything.
I was reharsing with a band so I can't remember exactly what i did before the device stopped working. Closing live and reopening the session corrected the problem. In the whole set, the only thing non-working seemed to be the device.
ciao
