Well, we've been begging for ages for regular hiphop ability in ordinary arrangers with no luck, so asking for regular arranger capability in a hiphop keyboard might be a bit futile (especially at it's price point)....

Let's just hope that this thing takes off like a rocket, and you might actually see some of it's capabilities trickle UP, for a change!

But I expect that Yamaha's (and all the other's) market research show that the hiphop and ballroom crowd are pretty much mutually exclusive (in general terms), so if ever much of this sound-set and arpeggiation ability makes it to a REAL arranger, expect to see very little except complaints from the older crowd.

And if you put older styles in the MM6, expect to see the hiphop crowd bail on it like a bad white rapper.....
