Hello Miko,
Welcome to the forum and my apologies for keeping you waiting; I had some personal matters that needed attending to.
I answered a similar question yesterday in this thread,
As for your second point,
Your request has been duly noted, but FxSound has never had such a Parametric EQ, and there are no plans to change the EQ, so I’m going to have to disappoint you there; sorry about that. Neutron and EqualizerAPO are two free programs with a Parametric EQ that come to mind. EqualizerAPO also has a wide range of built-in filters, including all the ones you described above.
