In MMD 060908 Arnim Whisler asked how to replace rubber rollers of
Piano Melodico.  Arnim, I could give you precise answers how to do it
for the smaller (30 notes) Piano Melodico as well as for the larger
ones (48 and 73 notes).  But you should wait for my answer until about
October 10 because I will not be at home until that date.  So please
let me know whether you could wait that long and what type of Piano
Melodico you are dealing with.
