Hi - I have for a long time dreamed that Yamaha would add a second "half manual" to a Tyros-like keyboard, so I did a quick, crude Photoshop of one. Don't criticize my PS skills, I did this in 5 min, very crudely.

Of course, button layout would have to be re-done, but this ought to be doable.
Since Yamaha doesn't make organs anymore, couldn't they do this - would maybe add 5 lbs. (pounds) to the weight, maybe add $500 to the final selling cost (I'd even pay $1000 extra for this) - have SOLO buttons (right next to RIGHT3) to register sounds to this mini-solo keyboard ...
Hey, forget about 76 key Tyros - I want a one-and-a-half manual, 93 (total) key Tyros! :-)
