Re: Optical scanner for Music Box Discs

Thanks for writing!

I will scrounge around for a small Stella;  I am assuming the disc
needs to be no larger than standard paper width (8.5").  I have
numerous 17" discs but the image would take up 2 pieces of legal size
paper.

What do you think of building a tracker bar (I'm assuming that this is
the bar over which the paper rolls and has the air holes) which has
photo cells for each track.  Each photo cell would correspond to a
circuit which would trigger the playing of a music note (each note
assigned to a Cakewalk track.)

I have a machinist friend who would be more than willing to build the
tracker bar -- I would need to get the photo cells that are small
enough to fit in each track (Stella tracks are about 1/32").  This
would be really exciting as there are literally thousands of Stella
discs (especially 17" ones) and the 26" Stella, while a less common
size, has spectacular arrangements of music.

I appreciate your input and will get a Stella disc photocopy out to
you.

Cheers,
