I recorded these works on a couple of the smaller positive style organs as well to publish, but then I discovered that EdoL recorded this sonata on the actual organ where Schnizer held his post. His excellent organ performance and a bio of the composer can be found here:

As the positive organs offer extreme clarity, it's very similar to the performance I offer you today of the last two movements from Schnizer's Opus 1, played on the Grimaldi Italian harpsichord built by Marioni in 2022, sampled by AB:

(
0:00) Movement 3: Intermezzo
(
1:35) Movement 4: Presto
So to get a contrasting opinion of the work on harpsichord versus organ, please refer to EdoL's version versus mine. I think this gives you a better idea than my positive organ version would, as it's very similar to my harpsichord one.
I will upload a contrasting organ version of movement 3 in the next days, as this one isn't yet represented in the CCH.
