Has anyone tried adding a midi controller to a T2? The M-Audio 88es is 88 key semi-weighted, weights only 17 lbs and cost <$200. They also have it with excellant basic keyboard sounds unit (88sx) that sells for <$400. More money can get you weighted keys in either (along with more weight).

I know multiple keyboards are not ideal. But for me, many times 60 keys will cut it (would always like 76), and only sometimes are 88 keys needed (like playing a broadway show).

I would love to see Yamaha come out with a Tyros module that could integrate (sit on top of) the keyboard controller of your choice (like MidJay). I don't know if Yamaha sees the arranger market as a good place for a module . However, I hope that their alliance with CME is a potential step in that direction. Note that CME is one of the few (only?) controller that lists aftertouch as a feature. I wonder if that is why Yamaha is partnering with them.
