Yes Alex,I am inclined to agree with you...it is fortunate that Yamaha is not the only game in town.
The lack of a 76 note arranger is certainly something they should have rectified,and with the Tyros 2 having such a great sound with the new SA voices,it would have made a wonderful basis for an instrument with 76,or even 88 keys.
Of course,if portability isn't an issue,the new CVP line will have the same features as Tyros 2 plus Yamaha's great Graded hammer keyboard...88 of the finest feeling keys on the market.
Of course if portability is an issue,the only choice is the competition...Roland and Korg make excellent instruments that would surely meet all your requirements...
All the best,
Ian
