i used the korg i5m module with a roland
a30 controller in a A frame two tier set up.
i now use just one keyboard Korg i5s. each has its own advantage. if you use a module
fiqure which hand to use to change settings
on the module. i use to place it on my left
but with the chord holding feature i ended up placing
it centered above the controller. with
the controller module setup, you get the benifits of a great keyboard feel plus
(my opinion) more flexablity. the down side is that you have more cables to hook up other than that its a matter of personal preference. hope this helps.
