With all the hightec features Roland is incorporating in it's units it amazes me to see the've ommited the things most people Want and NEED (eg: Voc, HD) in a top of the line or "PRO" model arranger KB, Especially for a working musician. Some of these companies really need to get in touch and LISTEN to the Needs of their customers by talking to them, sending out questioneers, and just have people that USE these KB units have a BIG input on future designs.
