What are Genos sales figures compared to Tyros 5 in the same time bracket?
Talking to the European dealers the T5 was a complete flop (Its only saving grace was the 76 note model) and paled in comparison to previous models, (They couldn’t get rid of them) however with the revitalised Genos they are selling them as fast as they can get them, (It even took Yamaha by surprise) which should answer your question In Europe.
The US is such a miniscule market for arrangers (I would guess that its right at the bottom of the sales charts) it may be different over there, but usually the trends are similar.
You will have more luck getting blood out a stone then getting actual figures out of manufactures (Except for a general response off the record) hence best to talk to the dealers.
