It seems a number of members are having problems with their new Kronos but many are very happy with theirs. So, I wondered if we could identify if the problems are across the whole production number so far, or are they batch (serial numbers) specific.

The combinations required to cover all eventualities would be too much for a simply poll so I have had to generalise to start with. I have kept things serial number specific but, obviously, a more detailed breakdown would include the number of keys (61,73 etc) and the problem type (keybed, fan noise etc).

I believe the fan noise situation is largely a matter of personal sensitivity/tolerance. So, unless the fan noise is obviously unbearable I would suggest this be ignored within this particular poll. I'll leave that to your discretion.

Finally, if you had a fault but it has now been repaired/fixed can you include yourself in the poll. This would help identify specific batch problems.

P.S. Fortunately, my K88 is fine. So, I am conducting this poll for the benefit of other members, not myself.

29th September Update

I have started another thread, asking for more specific details, so that a fuller analysis can be undertaken. The restriction on Poll Slots only allows a superficial breakdown here.

The new thread is here

I was just about to make a similar poll, but you beat me to it. Very Happy

Anyone who polls can add their origin (UK, USA, Holland etc) in the thread posts. This may also build up a picture.

Should have added an option for "not faulty", and which range you fall in.

If 50 people answer your poll and 45 of them have keyboards in the range of 0-300 for serial #, it will look disproportionate compared to what the actual results would be.

With the option for "not faulty" (and which range you are in), you can see the total number of respondants and then get a % of faulty given the responses.

Mine's an 88, no.878, and is fine, it must have been a large shipment to the uk, because I think I got hold of it at the same time as Panrixx - mid Sept. It plays beautifully, and sounds great.

Well, so far only nine members have registered having a problem. Maybe, more will come in this evening (UK/Europe) due to time differences across the world.

One problem with your poll is the fact that the same serial number appears in each of the models.

Korg considers these separate products, so the 61 has its set of serial numbers (starting at 1), the 73 its own set (starting at 1) and the 88 its own set (starting at 1). Therefore, you could have a 61 S/N 0015 that was fine, a 73 S/N 15 that was faulty, etc.

Also, most likely these keyboards are built in batches, e.g. a run of 61s, a run of 73s.

I think you need to have 3 sets of S/N ranges, one for each model.

Realistically I don't think you will get much out of this poll, given it assumes the problems are due to the human component of manufacturing. Some problems may be due to faulty parts, which would probably not have any relationship to the main S/N.
