Roland have 'been there, done that' with a LOT of good features.
Every new model line, it's add two new great features, drop one...
It's amazing that almost every popular feature on other arrangers has been tried (except mp3 and audio recording) and dropped by Roland. Just WHO in the hell do they ever ask about what to add or drop..? I know it's none of us...

But what do we know, anyway? We just buy and play the darn things...
