I'm experimenting with some 3-manual fun. Therefore I route all the ranks of the Doksy-Rieger set to my 3 manuals and pedal using jOrgan and can select from those. The swell still only works for the stops from the positive.
The first part is played with
I: Bourdon 16, Holflute 8.
II: Lieblich Gedackt 8, Nachthorn 4, Oboe 8
Ped: Bordonbass 16, Holflute 8
For the middle piece add
Trompette 8 to II , tuned to -3.1 dB
coupler Ped - I
