I'm looking for a keyboard that's going to used in the making of melodic death metal. I don't know much about keyboards, but I want to make sure I have the right one. My first question is, with regards to the Yahama moXF6 (which is within my affordable range), does it have the ability to split the keyboard to do two functions at the same time? I know the Roland Juno GI has this functionality, wasn't sure if the moXF6 does. This would also be played on stage. Thanks.
