Actually, everything here is purely Vierne's writing; I've just arranged it with the organ patches bolstered by some other, non-organ ones. I usually don't try to create clones of the many existing recordings of the works I do realizations of, but arrangements that hopefully give a slightly different and enjoyable way of hearing the works. So here, rather than just using softer organ patches in the middle, I split up the MIDI sequences into individual parts and assigned them to string pads, flutes, and an aaah choir, in addition to the organ underpinning. Likewise, the loud pedal lines are primarily an organ patch, but blended with double basses and a very soft low brass.
