I still think that the optical camera scanning system of MMM is
incredible.  I can't comment on the others because I have not seen them.
From what Siegfried told me at the time, I got the impression that the
machine can duplicate rolls by simply pointing the camera at a playing
instrument.  Joerg Wendel, is this true?  If it is, this would certainly
be the best machine I have ever encountered.
