ParametricFilterTypesandTheirUses
AwideselectionoffiltertypeshasbeenmadeavailableunderthePEQsectionwheneditinginputoroutput
filters.ScrollingthroughthevariousfiltertypesisachievedbyrepeatedpressesoftheENTERkey.Notethat
thiswillonlychangefiltertypesifthefilterisBYPASSEDortheGAINsetto0dB.Bypassingth
