Hello Larry,

I am impressed by the fact, that you built a device with
a technique I became aware of ten years later. This could for
sure be used to built a format free note roll reader.
But I am still searching for a modern, "state of art" solution
without mechanical parts.

Neverless many thanks for your hint, Horst
