Just picked up an SD40 from an individual. I updated it to the latest firmware/OS.

Among other things, it doesn't change to A while playing though it changes between B, C, and D just as noted in Dusan's post on Nov 17, 2016. Anyone else who experienced the same? If I can't get it fixed, I can still return it.

Thanks,
Chris

I try to run SD40 with my Tyros5.
Midi conection work only in Acordion mode on SD40.All ather option SD40 ignord.
It's inpasable to modeling intro and ending parts of style.
Swiching betven some main section (A;B;C;D) sometimes work properly,sometimes change section who you dont chouce.Example:
you want to change main variation from D to A,but SD40 change to B or C...
Registration cant remember with wich Intro you want to run a Style.ETC...
In one word,I buy an instrument who I cant trust for 1.500,00 Euro. Dont make the same mistake like I do...
