Wouldn’t that be cool!

And if it is reasonably priced, you wouldn’t have to get rid of your favorite arranger to get it.

If you have an arranger that you are comfortable with the layout, then just adding modules using the main arranger or a dedicated controller keyboard could be a good way to go.

But to do that more keyboard manufactures would have to start making arranger modules and we consumers will have to by them for them to do that.

Go arranger modules!!
