Fellow MMDers,  a friend of mine has recently acquired an upright
Blüthner (a German make) player piano which has many extra holes in the
tracker bar, including Theme slots.  It is foot pumped (not electric).
Does anyone have any idea what type of rolls this instrument will play?
I can send some photos to help identify the system.
