Mario Medley - Stepper Music Art

My art installation is finally done! I've spent way too many long nights at work on this, but the hard work has paid off.
Each hanging cube contains 2 stepper motors with 8 cubes in total: 7 clear acrylic and 1 MDF.
The MDF cube is the "subwoofer" with two NEMA 23 motors which each only play low notes. The 7 acrylic cubes each have two NEMA 17 motors that act as volume control. Louder notes make both motors play; quieter notes only 1 motor plays.
This means each clear cube is 1 instrument that can only play 1 note at a time. The subwoofer motors are independent giving 2 sub instruments.
This totals for 9 "instruments" in the band.

The whole sound ambience makes me think a lot of hearing the fanfare and bass register of an organ

Out of curiosity what microcontroller do you use to generate your square wave?

[@NotJustVR]

these are stepper motors and the microcontrollers are possibly an ardino and stepper motor drivers
