Subject: Re: [chromapolaris] Slider front panel not working properly

HI,
      i try to calibrate the sliders/Lever with Lower Function A7, A8, A9.
But he Polaris Sliders still works from 2/4 to 4/4 range.
For example, if i move the master slider  Volume from 4/4 to 3/4 the volume goes perfectly down, but when 
slider master volume move from 2/4 to 1/4 volume quickly goes down.
This is for all the lever on panel.
The two lever ( Bender ) near keyboard seem to work good.

I have also problem to do this operation :

R45 on Main Board -- ADC Range
Lower Function D 4
LED in master section do not light up !
I try to turn the R45 Clockwise and counterclockwise but nothing seems to work .

I also do not understand how to proceed to adjust the " lever assembly " voltage that should be between 2,0 and 3,0 volt.

What is the  lever assembly ?
The adjust.doc manual means lever = Bender ?

Best regards.

So what's wrong with the bend? Did you do the lever calibration? That's
LOWER FUNCTION, A, 7, then move both levers through their entire ranges,
then press LOWER FUNCTION again. It's probably a good idea to do all the
calibration procedures, if you can manage to follow them in English.

Sometimes it's possible to take a slider apart, clean it, and put it back
together successfully, but not always. It's easier just to replace it. John
Leimseider had some available back in September. If he doesn't respond to
your query on the mailing list, you could contact him directly at
john.leimseider@.... But try doing all the calibrations first.
