[ In this article, "feeder" is equivalent to "tracker bar". -- Robbie

In the recent article in 230401 MMDigest, "Seek MIDI File to AMI
Wurlitzer Converter", it was incorrectly implied that there are no
AMI maps for Wurlitzer rolls. I have attached the "standard" maps for
Wurlitzer Styles125, 150 and 165 rolls. There are two sheets in the
Excel file for each of the roll types. The first is a listing by feeder
position and the second is a listing by MIDI note.

Based on some bad personal experiences, I cannot stress strongly enough
that standard AMI MIDI maps should be used wherever available. I have
scanned many different types of rolls for customers and have often found
existing maps.

Whenever an existing map cannot be found, I have defaulted to a simple
map that puts the MIDI "notes" in feeder position order. This is simple
to understand and makes it easier to re-map in the future should that
become necessary.
