Pianoteq, the French makers of the famous piano modelings will release
next week an organ modeling. The blurb says:
"ORGANTEQ Alpha is a small organ with a keyboard range of 4 octaves
(from F1 to F5) and with 2 stops: a Flute 8' and a Flute 4' (octave).
It is provided in standalone mode only and should be regarded as a
foretaste of a more advanced commercial version in development, due to
be released during 2018."
