This sounds like a truly tremendous sampled instrument. I hope you also consider releasing it for Kontakt. I was playing around with organ sounds recently and noticed that they became a fair bit more natural sounding when closing a lowpass filter during the note releases. This allowed the sound to dampen naturally without either a hard stop or a bright swishy fade out. I think this effect( high frequency damping on release) happens in other instruments, but may be especially important in the pipe organ. It was pretty easy to set this up in Kontakt. Listening to the examples on your site I noticed that the note releases sounded a bit fast and unnatural in some places( despite the added release samples).
Another nice inclusion to this library would be an impulse response sample from the cathedral, if one doesn\'t wish to use the release samples.
It is really terrific to see a full sampled organ of this quality. Great work!
