We’ve taken a look at the Processor Editor software.
Regarding the IIR filtering, many brands have different interpretations of Q (or BW) in their parametric and shelf filters. And some have different frequency interpretations for Bessel filters.
We may consider adding this processor to our IIR filter modes, however it can take many months to work out the math for a new IIR mode and create all the conversion functions to/from all the existing Branded IIR modes that we have in our products.
In the meantime, I sugges experimenting with the filters in each of the existing IIR modes to see which ones may closely match the T.racks.
Best regards,
