I have borrowed the MIDI file for this performance from another user on this board; I very much love this tune, and it gives me an opportunity to try out some more complicated registrations and voicing while only owning one keyboard.
I discovered the MIDI file wants to play the trumpet solo on the swell, which isn't set up yet in my CODM. So, I used my 'Great Reeds on Swell' stop, and set the Great up with the trumpet. Unfortunately, this makes the chords on the Great sound a little muddy to my ear, but it's only a matter of time before I fix it.
I have Hauptwerk set to truncate releases to 1.5s, and am using quite a few demo sample sets to generate the stoplist.
