Here is an update about the optical roll reader I recently
purchased from Christian Blanchard, https://www.orgautomatech.com/ 
The reader really is a plug-and-play piece of equipment that took
only minutes to install and getting working in my roll mechanism.

The optical reader is a sophisticated but very elegant piece of
equipment which works perfectly.  Playing my bottle organs or
MIDI-operated harpsichords from a standard 31-note organ roll will,
I am sure, add to the understanding and enjoyment of my visitors.
