I would like to make a small correction to my posting of yesterday
regarding the cross-functionality of Phonoliszt and Phonola rolls.
Niels Berkers has pointed out to me that it is possible to play
a Phonoliszt roll on a Phonola piano as long as (1) the Phonola is
an early model without the Solodant feature, or (2) if it does have
the Solodant feature, then the operator should not operate the
Subdue levers whilst playing.
