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

hoi,

met een naam als pietersma ben je wel Nederlands, niet
?
geen idee hoe dit komt. als je hem via ebay had
gekocht zou ik een klacht indienen, maar je hebt hem
waarschijnlijk via een andere site gekocht, of niet ?
Moest het een troost zijn : je vindt regelmatig
crumars te koop in Nederland en Duitsland,
en als ik eerlijk mag zijn is ebay Duitsland de beste
plaats om synths aan te schaffen.

veel geluk

Tom

ps if you're not Dutch, let me know, I'll translate.
But you must be with a name like that.

Hi Artur,

I had a slightly similar problem. Every third key I pressed was either not heard or 
louder than the rest. What I did, was to select a sound with long decay and hold the 
3rd key. Knowing that a sound should be generated, I used the very unprofessional 
way of bending of and tapping on printing boards. It turned out that the filterboard 
was in need of some serious soldering. After having resoldered nearly every contact 
the problem was gone. 
Maybe it's just one of the CEM3328's. You could try to swap the one of the 2nd voice 
with one of another voice and see it the second voice remains the problem

groeten uit Nederland,

Niels

Hi Tom,

Yes... I am dutch, but still I like to do my msg's in english, so it's readable for 
everyone. Sorry for my late response, but for some reason I don't get my 
msg's in my mailbox (despite the preferences I set).

Anyway... I bought the Bit from a guy who really wasn't aware of these defects; 
in my opinion he did everything he could to help me solve the problems with 
the Bit.

On your advice regarding buying stuff on ebay Germany I have to agree: 
there's a lot to be found there.

Thanks for your response!

Artur

Hi Niels,

Thanks for your tips and sorry for the late response. Somehow I don't get the 
messages of this group in my mailbox.

Anyway... I already figured that it would be something like a CEM3328 not 
working and indeed... 2 out of 6 are really gone :(

Regarding the soldering tip... I think I'll do just that in one of my spare 
weekends. After having read your msg I inspected the board and indeed 
some of the solderings aren't too good.

Thanks again... 

Groeten, ook uit Nederland (Utrecht) ;)

Artur
