Thanks Rikki and Chris. I don't know how I picked up the wrong dimensions, but I did. This changes the name of the game. Back to the drawing board. The Korg Microkey Air, being so slim, may afford me more length. Most mini controllers are not meant for arranger application it seems, with split keyboard applications, and I need to know if USB will work like a din plug connection to the SD40. My needs are pretty simple, in that I control everything from the SD40 very easily. I will check this out.
