Forgot to mention, in Release 41A i never got this problem. Whenever i recall Drawbars, the Rotor was always automatically ON.

Please, could somebody with Release 41B try this on his Audya ?
Change from wathever sound (Piano, Trumpet, or wathever) to Drawbars and see if the Rotor automatically go's ON.

Thanks in advance,

Regards,
Carlo.
