Will, in Germany we have the word
http://www.dict.cc/?s=schnapsidee and
actually "Schnaps" is the German word for "hard liquor". I only want
to

reconsider, if an emotional, idialistic, euphoric feeling should be the
base to enlarge stage equipment by FLOSS, to replace a Nord Stage 2 EX.
Funny enough that indeed your project, Yoshimi, is a good reason to risk
something like this, but Yoshimi does not replace pianos provided by a
Nord Stage 2 EX.
