Jupiter 6 Filter frequency reversed

Post by 1way2life » Tue Jul 09, 2019 5:18 pm

Have a Jupiter 6 that I'm restoring... The problem is the filter frequency slider... it's reversed (fully open is on the bottom in LPF mode), and also the linearity is off greatly.. full cutoff is in the middle of the slider.

I swapped IC1 (4067) with the left panel, but same result.
Also, this is not isolated to one module board. All voices behave the same.

Any ideas are greatly appreciated.
