I'm looking for 76 keys for the same reason that many have stated already. But if an 88 note high end Arranger came along that weighed 30 to 38 lbs. I would get the 88 key for sure.
I doubt though that the Big Three will make such a beast in the near future. OTOH, it would be quite feasible for Yamaha, Korg, or Roland to make a light weight "76" note high end Arranger in the 30-38 lb. weight range or even lower. And a quality one at that.
A Controller is cumbersome because you need to carry around more 'stuff' and in this case an "extra" keyboard. No thank you. Obviously an all in one unit is ideal whether 76 key or 88 key because it is just one piece of gear. But a Controller with a Rack Mount is something to consider because a Rack would be much easier to transport along with the Controller keyboard.
If I used two keyboards in a tier mode I would want the two keyboards to have different sound palettes so as to have more of a variety of sounds and also sounds to compliment each other. A Controller on a tier with a master keyboard, whether a Tyros, etc., would only give you the sounds of a Tyros. But you would still have to lug around two pieces of gear to each Gig which is inconvenient to say the least.
No.. Rather give me one piece of gear that already has 76 or 88 keys, is light weight, and has a wonderful keybed plus all the other cutting edge features you would expect in today's high-end Arranger market. I would gladly lay down my hard earned cash for such an animal.
But apparently Yamaha, Korg, Roland, and the others don't want my hard earned cash.
Or the hard earned cash of a multitude of other keyboardists who simply will not settle for 61 keys anymore (or never did to begin with) but would gladly buy a 76 or 88 note high-end Arranger at the drop of a hat. If, of course, it met their other meticulous standards that is.
Like being light weight, cutting edge, and competively priced - etc., etc., etc... Oh yeah!
Best regards,
Mike
