At this moment a have a temporarily license of Martinikerk, Groningen. That’s a nice offer from Sonus Paradisi. You can use the full sampleset at home for free, trying it for one week. After that, you can decide to buy or not.
Since a couple of weeks I also have the sampleset of Haarlem. Therefore, I try to compare this samplesets. Earlier, I did that with a peaceful piece (http://www.contrebombarde.com/concerthall/playmusic/37482
Now, I recorded a preludium of psalm 35, the last couplet, that is based on this joyful text:
‘Let them shout for joy, and be glad, that favour my righteous cause: yea, let them say continually, Let the Lord be magnified, which hath pleasure in the prosperity of his servant. And my tongue shall speak of thy righteousness and of thy praise all the day long.’
The preludium is based on the Dorian Toccata (BWV 538).
I first recorded it on the organ of Martinichurch, Groningen. After that (2.45) on the Muller-organ of Haarlem.
The Youtube video is on the organ of Haarlem, with a bit more rear.
