Discussion about the Korg PolySix synthesizer

Hi all!

I just joined this list and thought it´s OK to introduce myself right 
away...

My name is Ami Hassinen and I´ve been a happy polysix owner since 
1989. I bought one second hand and have been using it ever since. I 
think it´s perhaps the most enjoyable polyphonic synth of its price 
range of the time...especially when you run it thru EQ and a bit of 
echo/delay. I have used it both in studio/recording work (my band is 
Nemesis - yeah, I know that it sounds like a veeeery unoriginal name 
now...wasn´t that bad in 1987...unluckily we decided to stick to it 
as it was printed on our album cover in 1994 etc...) and live set 
up...providing sterling service....until now!!!

Curiously (stupidly :-) enough, I haven´t replaced the battery yet, 
but have checked it regularly to prevent the leakage. I will replace 
it soonish with the help of the excellent tips page on the net (I 
think the author is on the list?) as soon as I have bought the right 
components. But the battery is really the original item and I think 
I´ve really been pushing my luck having not changed it ...yet :-)

The problems that I´ve had with it during the last week or two appear 
like this:

Everything is OK and normal for about 5-10 mins after I switch the 
unit on. After that time the programmes seem to lose some of their 
written features: the envelope settings disappear and all the sounds 
have zero attack and release. There is also slight fluctuation of the 
output volume. The program button 4 is (and stays) lit all the time, 
no matter what other program buttons one pushes (the appropriate 
program changes to the one being pushed on, nevertheless). Also the 
bank D (error) button is lit occassionally.

If I switch the unit off and it is allowed cool properly, after 
turning the unit on again everything is perfectly OK for 5-10 mins. 
and then the malfunctions appear again.

I would be very grateful if someone could enlight me if this is 
because of the very old battery or should I look the fault 
elsewhere???

I have a recording session coming on soonish and would like to take 
trusty poly6 with me...

cheers to all and thanks,

Ami
