You should. I get over 6 tuned octaves out of my A110's.

You might want to see if changing the scaling on the A190 helps.
It did for me. When I got my A100 it wasn't even in tune over
a single octave, but changing the scaling on the A190 did the
trick.

Sadly, the A190 now isn't outputing 1V/Oct anymore. I think
it's around 1.02V/Oct at the moment to get the A110 to track
perfectly, and as I'm adding other stuff, I might need to dive
in and recalibrate the A110's soon, or have all the other
stuff at 1.02V/Oct as well.

Trouble is, my volt meter migth be off as well, who'll tell!
