We have so many great choices at different price points. A good keyboardist will sound good on any of today’s offerings. For me, there’s no perfect keyboard. You have to set your priorities.

Roland has some SUPER editing tools but the thing weighs a ton! So you just have to decide which features are most important to you and what you can live without.
