IF you want something really intuitive. I would look at the Fantom series. The screens are amazing and easy to understand especially if you have ever used a DAW. Besides that you already have a Roland and know the ropes.

Korg PA would be second because of its live features dual cross fading MP3/seq players and a host of other nice live controllers and candy. Yeah its an arranger....but its a synth as well.

Piano is not all that bad either....lol
