Detail 01
Dedicated 8-bit processor
The module processes its key presses without affecting EM PRO performance when multiple modules are added.

Independent shopping perspective
Add one octave to an EM PRO mallet controller with this 12-note expansion module. It connects after the EM PRO Control Module’s end cap is removed, then locks into place to form a single five-octave, 60-note keyboard. The aluminum module keeps the expanded layout lightweight, and its dedicated 8-bit processor handles its own key presses. More modules can be added without reducing EM PRO performance, allowing the controller’s range to grow one octave at a time.
