Sub-Bass Drive and Extra Attack
The Sub's drive control uses an algorithm designed for sub-bass frequencies and tuned to its own sound set. Iceberg Audio says this lets the sub be heard on a wider range of playback systems. The drive control can add warmth and depth while keeping the lowest frequencies clear.
Extra Attack adds punch to the note. Rather than a standard envelope, each preset ships with its own Extra Attack profile. The developer describes it as a pitch-independent attack overlay, so each note hits with similar force regardless of its pitch.
