PAB Gravissimo

PAB Gravissimo is a special edition of the virtual pipe organ product family Palace of Arts Budapest Pipe Organ Samples. It introduces new features and contains virtual stops not existing in the real organ.

Specification and labeling differences

One of the most important differences between the original organ and the PAB Gravissimo is in the work of couplers. In PAB Gravissimo, due to the introduction of a versatile keyboard-to-division assignment feature, all electric couplers are relabeled and defined as divisional couplers instead of coupling just keyboards. In addition to these, PAB Gravissimo has an additional Tremulant on the Solo division and a new mechanical coupler IV+V m.

Also, in this virtual version of the PAB organ, many of the stops’ compasses have been extended wider than their original compass, to support transposing couplers and the inclusion of additional virtual stops.

The above table shows those stops that have separate switches directly accessing the extended compass range. In PAB Gravissimo, all together 78 stops have extended compass ranges supported by samples, of which 75 have one octave up, 38 one octave down and 35 both directions sound designed. Apart of these, Mixtur 4-6x 2' and Septnone 2x 8/9' + 11/7' on the Positif have a limited extension range upwards supported by new samples – the upmost notes are based on repetitions –, and Compensum 7x 2 2/3' on the pedal also has a repetition based extension. This means that nearly the full tutti has an extended range upwards by one octave; the organ has gained significant additional low-frequency power and majesty in the form of a downward octave frequency extension, as well.
