Subject: Re: [chromapolaris] Out of Tune

Funny, I was almost ready to write in with virtually your same exact question....but I had  the same problem  4 months ago , but right before i took it apart I seemed to  temporarily solve it with the "retune procedure'' in the manual.   Now the detune is  back but a little different and the  retuning wont solve it,  (sometimes the SYNC button realigns the oscilators on some sounds)  .. the answer I believe has to be  surgery. 
 
 I must finally replace the orange  Sample-and-Hold capacitors that keep the sounds 'stable' . they are very visible on the motherboard  ,They dont cost a lot and are available through Digikey.  All the info about this surgery  is posted on this  polaris site if you research further back. I was reluctant to dive in with the soldering iron, but others have written in that it is the  only answer to the 'odd detuning' problem,  Im trying to get psyched up to do it now.  at least you dont have to touch those ribbon wires.

Subject: [chromapolaris] Out of Tune

Hope somebody can help me with this.  Powered up today and noticed that the polaris is out of tune with itself- especially upper two octaves.  Seems to be every 3 or 4 half steps that are out of whack.  Otherwise, o.k.
 
Left it powered on for hour or so- nope.
Autotune all voices- nope. And all voices are tuning and play- so I haven't lost a voice.
Tune individual channels- after several attempts- sometimes worked, mostly made it worse- bumped it too high or too low- the beating got faster or slower- but still hear beats.
 
Last resort- full reset (I know probably an issue that calls for replacing components inside, but I'm lazy- and not good with a soldering iron).  Nope.  Well, at least now I can see if Soundiver still works and can load back my patches... and play them out of tune. . .
 
So, what can be done to get it back in tune?
 
Thanks
