@stephack I'm just starting to play with the Symfonisk Sound Controller using this driver. It's one of the smoothest dimmers I've used to date when combined with the linked driver and start/stop raising a dimmer.
Using button 4 (turn right) and button 5 (turn left) of the controller, I'm able to jump +/- 3 in volume of my Symfonisk speaker, but I have to turn, stop, turn, stop, etc.
Would smooth volume control, like smooth dimming be possible? Alternately, is it possible to map a virtual dimmer rise/fall to the volume change?
NM. Just found out the start raising and start lowering doesn't work with a virtual dimmer. 
i.e.
Button 4 start raising volume
Button 6 stop changing volume
Button 5 start lowering volume
Button 6 stop changing volume
Thoughts on also using this with Lutron Aurora? I have one coming today for testing.
