Over the Christmas break I uploaded a new website and some 12,000
MIDI files of reproducing piano rolls.  This has been a task in
progress since 2011, and was greatly assisted by being given
access to the Denis Condon collection of piano rolls before Stanford
University bought it and relocated it from Sydney to Palo Alto in 2014.

I am posting this information as there are MMDers who own instruments
fitted with MIDI-controlled valves, such as the Hunt Virtual valve
system.  As well, some MMDers have MIDI solenoid pianos (Disklavier,
PianoDisc etc).  Available are over 6000 e-roll files for playing on
an original reproducing piano fitted with a MIDI valve system.  These
comprise nearly 2500 Ampico files (A and B types), over 2300 Duo-Art
files, nearly 500 Welte-Mignon files and nearly 800 Welte-Licensee
files.  Most of the e-roll files are also available as standard MIDI
files for playing on a MIDI solenoid piano.  About a third of the
Welte e-roll files have been converted to standard MIDI, and more
will be put on the website as the conversions are done.

Readers may be interested in the catalogues (there are 32 of them).
These are all free to download, and might help fill in some gaps or
add useful information.  While each roll brand and musical category
(popular and classical) has three catalogues (by title, by composer
and by pianist), the three versions are not simply rearrangements of
each other.  Where known, birth and death dates of pianists and
composers are included, as is the issue or recording date of each roll.

All files on the website are available as downloads, and there is
a sale on at the moment to celebrate the grand opening.  Prices are
in Australian dollars.  I describe how the files are produced in
a downloadable document, and there are photos on the website of the
equipment I use to produce the files.  The website URL is
petersmidi.com.  (The usual www. is optional.)

Happy New Year to all readers!

 [ E-roll MIDI files are equivalent to an electronic record of the
 [ signals that emerge from the tracker bar as the roll is played on
 [ a pneumatic piano action, thus the performance sounds the same as
 [ when playing a paper piano roll.  Pedal commands are stored as note
 [ events outside the range of playing notes.  However, in standard
 [ MIDI files -- those intended to play a solenoid piano (or a synth
 [ piano) -- the pedal commands are stored as controller events, not
 [ note events.  -- Robbie
