we have got to give yamaha, korg and Roland etc a break! you all seem to want 76 keys, some want in built speaker some dont. But you all want it under 40lbs!!! 76 -88 note keyboards wont sell mass market. 76 Keyboards almost invariably have to be piano action semi weighted because the purchasers are usually piano players who need the range as opposed to arranger keyboard players who most certainly do not need the range ! If you need 76 keys then look to Ketron or Roland but from what i see , Ketrons latest board is 61 keys and the New flagship Roland E80 (which i am keen to hear ) is also 61 keys. I think the manufacturers produce what the market most wants and the priority is not 76 or 88 keys. Its predominantly less weight . Until the technologyg produces lighter weight materials you will never get an arranger keyboard 76 keys under 40lbs !!! it just aint gonna happen folks!
