This characteristic makes the standard, fixed-frequency EQ less effective when it is used to manipulate the instruments/vocals harmonics. <br /> <br /> SurferEQ tracks the pitch of the instrument or a vocal track and can change the EQ frequency accordingly in real-time, making it possible for the first time to naturally control the fundamental frequencies or harmonics of a track. Just set any of the EQ bands to a desired harmonic and watch SurferEQ move with the track, staying always relevant to the music.";
