Piotr,
Very professionally presented! I continue to be impressed by what you do, and it's even freely shared with fellow Hauptwerk organists. Felicitations and with my deepest gratitude expressed here for all you do.
You learn something new every day; apparently the "Violoncello" is a trumpet-like reed stop.
I noticed that when the manuals are coupled, you don't see the keys moving on the 2nd manual. Would suggest this as a patch fix so we can see when the manuals are coupled or not.
The acoustics here are half of the sound!
Are you still doing the sampling as an academic project?
Again, welcome back with a new sample set. I'm sure we will all enjoy it very much. Downloading it now.....
