In MMD 111220, Eliyahu Shahar mentioned, "This rare roll is
one of those that were produced for the Ampico from Duo-Art's
library after the merger of the two companies."

Any idea how this was done?  My specific question asks for the
procedure of converting the dynamic information.

 [ I presume an Ampico piano was placed next to a Duo-Art piano

 [ It's the same as making the piano 'reproduce' the performance
