While surfing the net I found this beautiful youtube. I liked this sound very much so I sampled it. This organ has been built by: Orgelmakerij van der Putten in the Netherlands.
One sample has been used which is transposed in an EMU E4XT to give it a bit of EMU niceness. After that a 3 sample/octave multi has been made in Kontakt (version 5). On top of that a simple GUI which gives it some synth-based parameters like Filter (+envelope) , Pitch and Amp envelopes. Have fun! Click here to download it
