The filter envelope values differ in the two synths, Subtractor and Thor. Subtractor ranges from 0 to 127, Thor from 0 to 100 as listed in the modulation bus routing section. As this parameter sets how much further the filter opens from where it is set, can we assume both of these filter envelope amount settings measure the percentage of the increased cut-off level? Is the signal in each portion of the ADSR envelope modified by the same percentage?
