Really cool!
Definitely for modern music, the answer certainly seems to be neither arranger nor arp/loop player keyboards, but a combination of both. They are two utterly different ways of generating stuff from simple note input, with utterly different end results…
I am so happy to be seeing arranger manufacturers finally embrace the merging of both forms of auto-accompaniment rather than jealousy keeping them away from each other, which they have been doing for thirty years or so. Remember, arpeggiators have been in some synths in one form or another since the 60’s! And an almost universal feature since the 80’s…
That’s how long we’ve had to wait… 🤔🎹😎
