Whch translates as almost perpetuum mobile (after all, it did come to a forced ending, as I felt I could continue to play like this for hours).
Meditative yet fast moving abstraction...
Start: Pedal Octav 8, RW: Flauta 8, Nasard 3
HW: Gamba 8 in lower regions mostly
Later some stops added, pedal 6' 4' and gamba 8' added with some counter melody in
the pedal, manual stops added, 4' flutes, 8' flutes, and then eventually it all goes back to the original registration and ends there.
Also: At one point I add the 16' Bd on the HW and add he tremulants doux and couple the manuals.
Not just a baroque organ, folks; very good for modern stuff too as has been demoed before as well.
I use a single touch screen at my right to change stops.
