Rhodes Chroma Polaris

My unit started acting up. 2 to 3 notes dont play on the patches. What real mysterious, different patches give me a whole new set of notes that dont play. eg... patch A1 (notes F# and D wont play) Patch A2 (notes A and C wont play) ?????? Anyone know whats happening. Dude from Synthtronic says it an Osc CEM3374??? Anybody recently have the same problem.

I can't imagine any mechanism that would consistently make the same notes
fail on one patch, while consistently making a different set of notes fail
on another. First of all, the autotune usually removes bad channels, so you
simply get fewer notes of polyphony. If there's a failure that doesn't show
up in autotune, then you usually get a pattern of good/bad notes that
repeats every six notes as you play a scale (or fewer if the autotune
removed a completely bad channel). If this is what's happening, the most
likely problem is that the volume offset calibration is waaay out of whack.
That's something you can fix yourself without opening the unit up. It's
described here:

et

A more remote possibility is that the analog switch that directs the output
of each channel either to the output bus or the autotune bus has gone bad on
one or more channel. If all channels tune, then they work, at least well
enough to make sound, but it's possible that one of these switches is
permanently routing the output of a channel into the autotune bus, so you
never hear it.

I doubt that there's a problem in a 3374. If that was bad, then the autotune
would almost certainly fail on that channel.

Could also be the CEM3372 filter/VCA. They tend to fail more often than 3374s. I have a few in stock if you want one.

I seem to have this problem as well. Out of Nowhere every 6th note will not sound. tried it over MIDI and same results. Also several membrane switches do not respond, which leads me to my question. Does anyone here know where a Polaris template for the Behringer bcr2000 could be found already made?  -Jeff

As I said in an earlier post, if the autotune doesn't reject the channel,
but you don't hear it, there's a good chance the problem is a volume offset
misadjustment. Readjusting it is free to try, and might solve that
particular problem.

whats a bcr 2000 and how does it relate to a polaris

It's a midi control module that has 32 assignable rotary encoders and 20 buttons. Perfect for accessing the parameters of a rackmounted, heavily menu-ized, or..... synths with touchy membrane switches that cannot be access anymore except through midi.  http://www.behringer.com/EN/Products/BCR2000.aspx  :)  -Jeff

thats a thing i never thougt about,
to access the polaris through a controller
like the bcr, maybe the apc 40 dose work too?
but,
is it possible to access any switch on the
(in my case) broken panel/board? thanks harald
