My keyboard is a SD1.
Even with the "on" set to Lower octave, under registration menu (on utility), all my registraton doesn't seem to affect the Lower1/2 octave on my keyboard.
I need +1 octave on Lower 1 and 2, and I change it on the arranger mode menu, but I can't save it to a registration!!!
It's such a shame!!

Am i doing something wrong or the keyboard doesn't save it? could it be a bug?...

Thanks in advance...
