Volcano 3 - Peak parameter automation issue
There is a confusion about "Peak" parameter in Volcano 3, the envelope of it in a DAW doesn't start at 0 when it's all the way down.
In Bitwig Studio: Peak knob is on 0 - it's 50% automation envelope (in the middle), Cockos Reaper: Peak knob is on 0 - it's 0.000 envelope instead of -1.000 (in the middle of automation).
For example if we look at Drive knob behavior: -18.00 (minimum) value is -1.000 in Reaper (envelope all the way down) and 0% in Bitwig (all the way down a well) etc.

The peak parameter in Volcano 3 only has positive values with some filter types (high pass, low pass, band pass, notch and all pass) and positive and negative values with other filters (bell and shelves). When you are using filter types that only have a positive peak value, the lowest peak value will indeed be 50% if the automation is shown in 0% to 100%, or shown as 0 if the automation is shown as -1 to +1.
When you are using a shelf or bell filter, the automation should go to the lowest possible value in the automation lane.
