one of rsn's downfalls is the lack of absolute filter frequency values...of course there are other synths with this issue, but not many...

i've tried looking around for some sort of conversion guide but no dice. of course, no two filter ranges are alike...

does anyone know the hz output range of the filters, or how to calculate the frequency value?

The Thor shows correct frequency values. For the other devices I see no way to get the real numbers, because you don't know the exact min-max-range.

BUT: Why not trust your ears? Don't bind yourself to numbers. I never look at the numbers!
