Ranks’ audio can optionally be routed directly to primary mixer buses, instead of via groups, which avoids the need to set up (or use) groups if routing ranks to individual speaker pairs. The “Organ settings | Rank routing …” screen has been renamed accordingly, and now contains primary bus entries in its dropdown lists of destinations, in addition to the existing group entries. (Note also that output perspectives 2-4 are now routed directly to primary buses 2-4 by default when loading a new organ or resetting its rank routing, although default groups 2-4 continue to exist for compatibility with previously-loaded organs.)

Hauptwerk has 4 per-organ ‘rank routing/voicing presets’ (in addition to the existing 128 audio ‘mixer
presets’, which aren’t organ-specific, but each organ specified which of them it would use). Each one
defines:

Which of the 128 mixer presets of it should route to.
A complete set of rank routing, as defined by the “Organ settings | Rank routing to audio mixer
buses/groups” screen, with expandable nodes in its left-hand rank list for the four rank
routing/voicing presets.
A complete set of rank voicing, as defined by the “Organ settings | Rank voicing and surround/3D
panning” screen, with expandable nodes in its rank list for the four rank routing/voicing presets.
