The fundamental design of the guitar involves using linear solenoid actuators to depress the individual strings in different regions of the guitar neck, as seen on the left.

Solenoids will be controlled, as with the other instruments, by a single Teensey 4.1 microcontroller. These 3 controllers will then be connected to a central Raspberry Pi, which will accept MIDI files and break them down into the instruments' respective parts. To the right is the PCB layout to control the solenoids.

Currently, I am working on prototyping the design and making final iterations to the system. This involves testing the solenoids pressure, current draw, and voltage, as well at the fit of the neck of the guitar into the brace of the structure, as seen on the left.
