Glenn Thomas wrote an excellent piece on Wurlitzer band organs for the
COAA (Carousel Organ Association of America) magazine for July 2013. In
it he says that the more-or-less definitive MIDI scales for the 165 and
150 are the "AMI" scales. I've seen and downloaded the Wurlitzer scales
here on MMD, but I am not familiar with the AMI reference.
I am also familiar with the scales used for the Wurlitzer band organ
roll scans in the player piano lists, which differ a bit, I think, from
Robbie's scales.
Is AMI just another name for one of these the scales, or are or is it
something significantly different?

[ AMI stands for the Automatic Musical Instrument player system
[ developed in the 1990s by Mike Ames. It's not just a scale. The
[ system uses two 64-channel MIDI output circuit cards. The MIDI file
[ stores data for the Bass, Accomp and Melody divisions as Channel 1
[ data; the remaining data such as Countermelody, percussion and
[ register (lock & cancel) data are stored as Channel 2 data. See
