Hi all,

I recently bought a Bit One on a local advertising site. It has a very odd 
problem: every second key I press doesn't create a sound.

For example: ABCDEFG gives ACEG, but if I take the SAME octave and I start 
with B, then BCDEFG gives BDF.

Does anyone have a clue to what is happening here? :)

Best regards,

Artur
