A small interesting instrument, which gives us the impression of entering the house of a rich inhabitant of Utrecht in the 18th century. It is a organ with serious sonorities, a bit austere, and very nice attacks. No reeds, no mixtures. One can regret a lack of power for the first octave, almost inaudible and irregularities between the notes. It should be possible to correct it, I suppose. The absence of multi releases is not a problem because the sample set is almost dry. It can be loaded in both versions with the free evaluation version of Hauptwerk (from the 4.2). But, for those who can, a 24-bit load makes a big difference. Also a contemporary temperament gives this instrument a lot of character.
Welcome and good luck to Akkerorgels.
