Prophet 6 filter tracking

Prophet 6 filter tracking
« on: February 12, 2022, 07:44:05 AM »
Hi, I know the filter is stepped to semitones when on full keyboard tracking, but on my Prophet 6 the filter tracking is off with approx -40 cents in the lower octaves and +40 in the higher. I can maybe get 3 notes in the middle in tune. The regular calibration process (preset + 0) does not help. Is there any other way to tune and scale the filter?
