I have tried several arrangers from Technics, Roland, Gem and Ketron, along with Yamaha.

In my opinion, Yamaha are the best, the only downside is , yes, the Tyros price and the fact that the sequencer is a bit outdated, but I use it because it has a very useful 'Chord track', which Roland and Ketron does not have, which is odd.

But yes the price for the Tyros is too high....
