The mix value affects only the wet/dry balance within the effect; it is independent of
the mix levels for Effect 1 and Effect 2 (the L parameter described in section 4.2).
4.3d EQ Parameters
EQ alters a sound's frequency response. Example: Boosting the lower frequencies
gives a bassier sound; boosting the higher frequencies gives a brighter sound.
The DPM V3's EQ is a two-channel, shelving type (so-called because the frequency
response creates a "shelf" starting at the chosen frequency). The figure below shows
some typical response curves available with the EQ.
