(New): I would like to propose improved 'cabinet dimensions' for arranger modules:

Current modules are too boxy (Ketron Auda 4: 21"L x 13"W x 5"H), making it difficult to access 'on the fly' all the button functions from the keyboard playing position (with module situated directly behind the kb controller), because all the module's button/slider functions are so tightly crowded together within a very limited confined area.

To solve that problem, I propose changing the dimensions of the module to something long and narrow, ei: 32"L x 7"W x 5"H. This would allow the arranger functions, sliders, and sound/style access buttons to be grouped, arranged & spread out 'across' the keyboard for far more convenient & reachably accessible' from the player's seated position, especially if the module is able to butt up directly behind & against the keyboard controller.

A pop-up style tilt screen would further enhance the arranger module experience too.
