when the drone is mostly in the low side of the keyboard, it's normal.
afcourse it's always good to sometimes give a new instrument a service 
especially when cracking pots and or keys appear.
on the whole just play and enjoy the ds2, unless someting is really6 
broke, it's normal/analog.
i have two , alweays a soft dronesound in the first octave of the 
keyboard. big deal for me, i love them,
congratualations, sunny
