Reduced size and a bigger touchscreen

Faster CPU:
Don't get me wrong the SSS is great, but when fast switching between performances is required it still takes a lot longer than you would want too.
I know there are a lot of workarounds to suit your workflow. But I am talking about switching between 'Full' performances with their own benefits (motion control, effects, parts, settings, etc).

Custom Keyboard:
Keyboard with the same dimensions as the Balanced Hammer version. So not heavier but still Semi-weighted (bigger) keys.

Reducing weight
Alternative for aluminum to reduce weight but still strong enough for heavy duty stage use. Maybe carbon fiber but I think would skyrocket the production costs. But for a collector's edition who knows…

Yamaha if you're making this a reality, then please send me one for the idea haha :p

I dared to dream, discuss… 🙂
