Hi All!

I just got a Chroma Polaris. Great sound!

The sliders are a bit worn out I think. In particular the cutoff
slider jums all over the place when you move it. Before I start
unsoldering/cleaning/etc, do you have any advice?

Also, it has some problems with the membrane switch tail. It has
already been tipped over with silver paint, but it is still flakey. It
worked fine at the seller's place, but as soon as I got home the top
row of bank selects failed. I opened it up, pushed the tail a bit, and
it worked again. Looks like it needs a more definite solution than
silver paint.

And last question, it has V5 firmware. Is there any advantage to
upgrading to V9?

Thanks,
Ben
