I simply don't get it...

If Yamaha think that 'pros' need a choice of 61, 76 and 88 keys for their Motif line, why do arranger users only need 61 for their 'pro' Tyros2...?

It can't be cost... can it? They HAVE painted themselves into a corner by making the T2 61 so expensive that the hike the larger keyboards MIGHT entail would push a 76 or even an 88 (wouldn't you just KILL for a T2 with an S90ES form factor? ) into Oasys country. But the truth is, there is very little basic cost difference between a 61 and a 76 note keyboard and case (in fact, there is less than $200 difference between a Korg TR-61 and a TR-76 at retail level and no more than about $500 for TOTL workstations, which the T2 keybed and case don't honestly compare to).

So what would it actually cost Yamaha to find out if everybody that clamors for a 76 T2 is just blowing smoke? Not a whole lot, compared to what they could gain, IMO...
