I have been hearing about the death of of arrangers for the last 15 years .
Substitute organ for arranger and those are the exact same words that were used before organ sales reduced. (And many manufactures disappeared)
Go to any dealer and they will tell you that the arranger peaked around 2010/12 and has been downhill ever since. (Yamaha’s T5 was a flop compared to earlier T’s with only 76 notes giving some saving grace, hence the Genos)
NOTE: the arranger will not disappear, (Just like the electronic organ has not disappeared) but it will become a very niche market. (Way more than it is now)
