I bought it online, and still waiting for it to come.
The same day, I tried it 5 minutes in a music store close to my work.
The keys seems very cheap and a little smaller and shorter than usual. I will compare with my other KB when I will get it.
The BK5 was close to the Roland Atelier Organ in the store and this Keybed was a LOT better.
It is my first Roland KB. So I will see
I bought it as a Roland reference KB to help my users when they will ask questions about Roland styles on vArranger
I will let you know !
