Maybe it has to do with the counting method of program change used to set
the clock divider of the A-190-1. The A-190-1 manual was written in 1996 and
at this time it was common to count the program change numbers from 1 to
128, today it's common to count 0 to 127 (in newer user manuals we point out
to these different counting methods). Try to use other program change
numbers (e.g. 2 instead of 3 and 5 instead of 6). Maybe then it works.
