From as long as I have been a member of the zone ,the death of these keyboards has been prophesied. But there are very strong reasons why they are unlikely to die out just yet .

In fact workstations and performance keyboards are more likely to die out before arranger keyboards do because of the availability and integration of iPads and various apps .

The arranger keyboard market is dominated by folks who in general

1. are not technologically proficient.
2. Are incredibly loyal to brands
3. Like new innovations but not so widely different to what they already have
4. And have the desire and the money to upgrade their keyboard everysingle time a new addition comes out and lastly
5. routinely do so every single time a new addition comes out.

What is likely to happen is that the pure arranger market will become less diversified Meaning that the likes of Roland will probably disappear and we will be left with Yamaha korg and possibly ketron or even a new company coming into the market

I predicted a few years ago that arranger keyboards would morph into workstation crossbreeds. And certainly we have seen this in the likes of the motif and the Fantom the kurzweil pc3 etc .

Arrangers will update but not die for sometime to come .
