Walter preset - worn condition

I've just played the Walter piano since last update 4.5.1 (Pianoteq Stage), and the Walter appears to be in worn condition. Which is fun but mostly unusable :-)

I would be happy to get the Walter back ! (and I would gladly welcome an update of the historical instruments which now seems a bit artificial in comparaison with the last D4, Bluthner and U4... thoses historical pianos are my principal interest in pianoteq... (The Erard is also a bit odd. I practiced Erard pianos from the early 1900s and the trebles didn't sounded so strange)).

But maybe I'm wrong ? :-)
