I am getting really excited when I hear of the chance to get the image
of about 500 Ampico rolls.

My major motivation to gain access to these data is the fact, that I
have built an electropneumatic controller that makes any selfplaying
piano MIDI compatible.  I have reported about this before in the
digest.  Therefore I would be interested in the version without
velocity information, i.e. the expression should be still coded in
separate tracks as in a real image of the rolls.

I think most other people would prefer the version with encoded
velocity.  Anybody that owns a soundcard (SB16 or better) can listen to
the wonderful music that has been preserved on those rolls.  This
includes me, too.

The question I have in this area is:

    Which algorithm did you use for converting the expression tracks
    into velocity information?

So, as everybody can see, my interest is really strong to get access to
both versions.  As the conversion from expression tracks to velocity has
been done once, it could be repeated any time, maybe even with
different or optimized algorithms.  The other way around seems to be
more complicated and in my opinion it is not yet clearly defined.

With best regards
