The purpose of this posting is two fold.  First, to inform of an
ongoing project to convert Aeolian 116-note organ rolls into MIDI files
that will also contain Duo-Art organ control codes.  Second, to request
input and source material.

The 116-note roll library is about twice as large as the Duo-Art organ
roll library of 545 titles.  Many rolls within the 116-note library
also exist as fully coded Duo-Art automatic rolls.  It appears that
almost no new material was issued in either format after Aeolian and
Skinner merged into the Aeolian-Skinner Organ company.

The earliest Duo-Art rolls were merely "arranged" 116-note rolls that
Aeolian converted into the Duo-Art format.  A little known fact is that
late in production, prior to the merger, some hand-played recordings
were issued in both formats.  Some hand-played 116-note rolls never
were issued as Duo-Art rolls.  The point is that many 116-note rolls
contain excellent music worthy of conversion into the Duo-Art format.
The better "arranged" rolls also make wonderful Duo-Art performances.

My problem is deciding which rolls to convert.  Reviewing the
116-note rolls to choose an upgrade candidate is a very time-consuming
process.  I have taken several approaches to making logical selections.
Overtures seem to be popular with most of us, but they tend to be huge
rolls, so I have avoided those.  The opera category is a huge portion
of the 116-note library and many of those rolls exist in both formats,
so I have avoided that category for the time being.  I have tried to
focus on composers that I like, such as Mendelssohn, Gounod, Lemare,
and Hollins.  I would love to hear from MMDers of any good areas to
explore.  Rolls that don't sound mechanical are what I really seek.
Any suggestions?

I am also looking for people who own 116-note rolls that are willing
to lend them for my project.  As an example, I am missing the last
movement of the Beethoven Symphony 3, Eroica (roll # 1173, IV Finale,
Allegro molto).  There other multiple sets where I have just one roll
missing, and I will probably post those wants on my web site.

Any help would be appreciated.
