Not as many wires as you think Donny! Big misconception is people tend to think that it's much harder than it really is
Out of the box all you'd need is ONE midi cable to use your S900 to control the module
Remember I'm talking FULL featured module. Not some dinky box with no buttons and just full of sounds and styles. Look at the V synth rack. Imagine a box like that with all the style controls there just like any other arranger, touch screen, and more. You'd be short one big ass keybed and all the weight that goes along with those keys and the massive shell to house them
