I think the learning curve is not a hard as you may think it is designed to be very user friendly it looks like it might be hard but if you watch some of the vid out there not too tuff at all

out arranger keyboards are just as deep

I personally think this will be a great addition to my rig

not always will i take it along but the times i do i will have the best of both worlds at my finger tips.
