Prospectum proposes a new version of the sample of Maihingen. I find the sound very clear. The organ sounds in its original state with some imperfections... all sounds very natural (imho).
To record this little demo I decided to play some little pieces composed by Wolfgang Ebner (1612-1665) organist in WIen. He let us a collection "56 Versetten durch die acht Kirchentöne". Each pieces shows a registration.
From the beginning to 10:06 you listen to the stops of the Hauptwerk recorded separateley and combined.
From 10:10 to 13:30 I do the same with stops of the Rückpositiv.
From 13:30 to the end I record some possible combinations between both keyboards.
This music doesn't need pedal or for some cadences only.
