Hi!
Registrations are unsure for me too, they do not always do as it's programmed to at first pressure,
only at second pressure it will be correct.
So you can not trust Genos registration, on all occasions, it's a pity.
Hope Yamaha fixes this in the next upgrade.
I got three voices at the same time, I had just programmed one voice (Right 1),
and the three voices were not shown in the display, they were hidden, strange.
