Speaking only for myself, I suspect that there haven't been many replies for two main reasons:

1) It isn't really clear what the 'problem' is
2) It was already noted that "...No o-scope...am no repair tech"

First - without having a good description of what is really happening (under a controlled setup) there's no easy way for anyone to make a meaningful suggestion as we don't know exactly what you're doing (hence what you should be seeing).

Second - most of these sorts of issues are 'easy' to diagnose if you can follow the signal with a meter and/or scope - but if that's not going to be possible, then as much as folks might want to help, it becomes very difficult (and not very likely) that some sort of generalized 'do this and you'll be OK' comment can be made.

Some thoughts as to how it might make it easier for people to help.

First - start with a 'standard' configuration that other's can duplicate/evaluate.

For instance - let's start with a 'scratch' patch. Select patch A1 (for instance). Then select Upper Function, Erase Prog, and select "1". Now, when you press the "A" bank, you should see that A1 isn't lighted. Select A1 and you will year a 'basic' sound.

You can then document what specific settings you are making - for instance:

Osc 2 Sync button on
Cutoff Slider to 3/4

Now - if some concerns are being seen with the Resonance slider, you can describe what that means/how you see it.

For instance - if with this setup perhaps you don't seem to start to hear any change until the resonance slider has been moved about 1/2" and/or perhaps you don't happen to hear any further changes when the slider is in the last 1/2" of travel or so - then this is likely 'normal'.

It is important to keep in mind that the Polaris doesn't have direct analog control of the parameters. That means there are a finite number of selection that the sliders will give you. Some have more, some have less. For Resonance, there are expected to be a total of 8 levels. So - whether or not there is a 'dead zone' at the top and bottom of the sliders, the key is whether you can hear 8 different settings as you go through the range of the slider. If you do (and if it is increasing/decreasing in the moved direction) then likely all is well.

Please note that a 'clean slider' doesn't necessarily mean a 'good slider'. It is absolutely possible to have a worn-out or loose slider that feels good, and slides nice, but it may not actually be making the contact as it should. You can use a simple multi-meter to measure the voltage from the middle connection of the pot, to see if the voltage does cleanly slide from 0v -> 5V as the slider is moved from one end to the other. If the value jumps, or is erratic - then further attention is required to the actual slider.

Note - it would be expected that all of the items in the "Adjustments and Checkout" section of the Polaris Service Manual would be reviewed and checked.

Good luck with your efforts - and hopefully with a few more concrete observations the people on the list will be able to give some more concrete suggestions.
