Scott,

What do you have the reference note set to  

I'm not familiar with the A-190-1, but on the  A-190-2, I press the button to get into Learn mode, then press a key to send the lowest note I want to be able to play ("reference note").  It then accepts 5 complete octaves, starting from that note - so if it was a C, it would play 5 octaves from C to C, but if I set a B, it would play B to B.
