Im not experienced yet but ive read and hearf about of filters wither it be pro tools,waves,analog,any plug in can do more than give u low pass or high pass but some can change the tone. Im at audio school and a intern that told me to use a different eq plug in cause he said it sounded way better than pro tools and i was freaked out a bit cause my thinking was like” this is digital not analog so how can it be different”. Also over heard a chief enginner say to another pro that good filter are hard to find so im assuming theres truth to this. Mainly bringing this up cause im thinking of getting a old akai s950 to sample drums and use the filters in areas they need. So any real techy enginneers with real answers that would like to shed some light on this?
