Unfortunately there are only a few recordings with the real Cappel Schnitger available. I do have the CD with Egbert Ennulat and although I like his style of organ playing not that much (I do like for example Gustav Leonhardt's style very, very much - I heard him last week in Norden/Germany with the great Arp Schnitger organ, it was so wonderful!), however the recording is welcome to compare the real Cappel Schnitger with the HW version from Milan Digitalaudio. I recorded some bars of the CD pieces myself with HW and of course using the same registrations as Ennulat. The result was interesting. The Ennulat CD has more room sound, maybe because of other microphon positioning, maybe because the audio engineer added some effects to the recordings - I don't know.
It seems that the Hauptwerk (of the real organ ...) sounds more brilliant (and louder?) - anyway the CD give me this impression. Remarkable detail: the Scharff in RP is always much more present on the CD recordings, i.e. Sweelinkck variation 6. This can be changed with HW voicing options with good results.
Meanwhile I created a custom organ file for the Cappel succesfully (only for own use). Most work was to find the correct amplitude levels of the stops (the original ODF is encrypted). Since this work is completed the organ sounds nearly identical to the organ with the original ODF. So Brett, I think there are not so many important settings in your ODF which influences the sound very much (mainly what not could be done within the CODM). I have enlarged the compass of the manuals and the pedal. Also I have added an "Oberwerk" with stops from the little Eenum Schnitger organ (the room sounds similar).
