Just bought a DB I preordered.
Playing the demo model in store noticed this issue, and mine does it too.
If you have either of the bass drums playing either manually triggering or with steps, like a 1/8 note boom boom, if you move the volume pot for the track it sounds like it is dusty - the ole' crackle and fizz. Sometimes it even attenuates the volume after you stop moving it. Only does it on the 2 bass drums. Doesn't make any noise moving volume pot when track not triggered.
Haven't had a chance to FW update as I am visiting the city to buy it, and computer is at home.
Also noticed some noise on the filter channel when not bypassed - kinda sad to hear it - this is while using quality headphones,
Oh and the tap tempo light is in super strobe mode and doesn't follow the tempo...
Anyway, any one else have "noisy" pots. Firmware issue or mechanical?
I will need to return this in a few days before I head home - kind of a bummer as I had such high hopes.
