I checked the karma yesterday at the store and I see no noise on it. so may be they fixed it.I see the version of the keyboard are 1.0.2.
I like the keyboard by the way and I heard some new sounds too. or some re edited sound from the triton.but what I find not good is that the keyboard is hard to scale and not as fast as the triton in picking sounds (for me at least).
Arvon...
I got worse than that from Roland on their XP-30 and the E-500OR
