I just updated my Maestro Sounds site with release samples for the Concert Grand piano. They are sounds of the keys being let up and dampers coming back at the strings (Clonk, clonk). They are not \"real\" release samples which are impossible to get right, but they do the trick pretty well, adding a subtle thump as the keys are released. They come in four \"velocity\" layers. The art file also contains Rick Chadwick´s improvements to the transitions between f and ff, with a filtered ff layer.
Don´t worry about the download size, you don´t have to download the entire piano again, the release samples can be fetched separately, with their own art file. There are instructions on how to combine the two files.
The page is also updated with a new brush snare replacement kit, containing just that, a mono sampled snare with a bunch of samples... in soundfont format. Check out the news page.
