I would still be interested in the stats on the TOTL arrangers. Let's face it, these things are voiced for Europe, in fact, YamahaUK have a strong part in styling and voicing them (remember Andy [The Insider], one of the main demo guys for it is from UK), and the ROM styles have barely a trace of Asian influence.

When Yamaha DO voice an arranger for the Asian market, they release a special model (S700-OR e.g.), so that definitely seems to indicate the Tyros is firmly and squarely aimed at the European market (and a rag thrown to us poor US players!). There CERTAINLY isn't a T2-OR, now is there...?

Just because Yamaha are strong in the music education field does not in any way equate to arranger sales in a demographic where they don't actually produce a keyboard for that area's music...
