Currently there is no 4th manual, not with pipes nor digital. The proposed swell was 11 stops large with an extended compass, both the bass as the treble would have an extra octave of pipes.
Our (J.L. van den Heuvel Orgelbouw) proposal was:
Double walled swellbox in Van den Heuvel construction. Shutters 5.5cm thick. 18 shutters of 22cm wide. Box dimensions: (hxbxd) app. 2.9m x 4.7m x 1m.
CC-f4 (78 notes, organ compass is C-f3 54 notes)
Bourdon 8' 78 pipes
Dwarsfluit 8' 54 pipes, CC-B from Bourdon 8', harmonic from f1
Gamba 8' 66 pipes, CC-BB from Bourdon 8'
Voix Céleste 8' 54 pipes, from c0
Openfluit 4' 66 pipes CC-BB from Bourdon 8', harmonic from c1
Salicionaal 4' 66 pipes, CC-BB from Gamba 8'
Vioolmixtuur II-IV (dulciana scaling)
Tuba 8' 78 pipes (english shallots)
Hobo 8' 78 pipes (cavaille-coll scaling)
Clarinet 8' 54 pipes (cavaille-coll scaling or as free reed)
Vox Humana 8' 54 pipes (cavaille-coll scaling)
Tremulant
This floating (!) swell division would have slider chests with electric action. The original mechanical action will be left as is.
Couplers to the manuals and pedal at 16', 8' and 4'. The division would have had its own windsupply.
