Let’s say I have a sample sampled at C-4. I play melodies with the white keys only, so CDEFGAB.
I would like to find out a way of mathematically going: “OK, these are the frequencies for each octave of CDEFGAB” - and boosting those frequencies with an EQ plugin (EQ8? FabFilter Pro-Q?). Or: alternatively, kill the frequencies that are C# D# F# G# A#.
How would I go about doing this kind of “cleaning up” frequencies of a sample?
I’m thinking “select the contents of a channel, press a key -> EQ8/Pro-Q boosts the frequencies I play at, and kills the frequencies I’m not playing at”.
Any ideas how to go about doing that?
