Additional stops and extended compass

The Gravissimo Edition features 149 stops all together, based on extensions of the original 92-stop organ. The extended stops were sound-designed using the original samples but they are unique samples.

The 57 new stops include two 64' stops, seven 32' stops, two chamades, two tubas and more. These additional stops play either the extended ranks or in a few cases already existing stops from a different division. The extensions can be loaded individually allowing you to configure the overall tutti sound further, even when using the super or sub couplers. All together, 75 stops extended one octave up to support super (4') couplers and 38 one octave down to support sub (16') couplers, 35 extended in both directions. The most important 57 additional stops have individual switches while the sound of other extended ranks are available through the sub (16') and super (4') couplers.

All divisions, including the pedal us enclosed in this Edition. The two originally enclosed divisions of the real organ are kept intact as the previous editions include them, while the other four are also enclosed allowing maximum flexibility. The enclosures can be assigned to the available three swell pedals. To support different organ consoles and usage types, the 3 swell pedals can also be coupled freely for a joint operation. Additionally, you can limit the operating range, set the operating curve and direction of each pedals individually. The global pedal direction selector introduced in the Extended Edition is also maintained for convenience.

The original organ of PAB features mechanic and electronic couplers. Exploiting this feature and combining this with the manual-assignment feature, all electronic couplers became divisional couplers (i.e. coupling between divisions irrespective of which manual controls them) and all mechanic couplers remained mechanical, coupling keyboards labeled with numbers. Therefore, all electric couplers are re-labeled to feature the divisional directions, providing easier use, while the mechanic couplers remained as introduced in the original organ. To complete the list of mechanic couplers, 'IV+V (m)' was introduced to the fourth manual. Additionally, about a hundred electric couplers are introduced providing nearly all possible coupling directions, including reversed, transposing and split couplers as well as unison off. Unison off allows you with a transposing coupler used together to transpose a division one octave up or down which can be very handy for solos or improvisations, and provides an entire new layer of sounds. All non-transposing couplers (such as Pos to G.O.) and transposing self-couplers (such as Pos to Pos, 4') have bass and melody solo switches that transform the source voice into a solo voice, either bass (lowest note) or melody (highest note).

To support organ consoles and operating environments with less than 5 manuals, an easy-to-use manual-to-division assignment feature is introduced that allows you to assign any of the five manuals to any manual divisions, even more than one division to a single manual. Furthermore with a single click you can change the order of the organ's manuals from French to German (swapping the first and second manuals) or assign them in various other orders of your taste. These, among with the KeyboardMass™ and swell pedal characteristics can be saved in the unique PerformanceSequencer™, which allows you recalling a different organ configuration with just a single click, even during a concert. Alternatively, with a selector button, you can request PAB's own Combination Action system to recall these features, individually for each frame. This carefully designed pioneering system provides you a flexibility and ease of use never available before. You can now decide to perform and practice pieces authentically in the keyboard order of that given era, or use one keyboard assignment for all - and manage this with a single click on the screen.
