For many fans of digital music, nothing beats the synthetic sound of a MIDI-based tune. This Lo-Fi Orchestra project was created by maker and musician Kevin (@diyelectromusic) It uses multiple Arduino boards and one of our favorite SBCs, the Raspberry Pi Pico.

The Arduinos are programmed to generate sound featuring a variety of effects. The Pico is mainly used to provide visual output for the audio as it plays out in real-time.

There are multiple types of Arduinos integrated into the system including Arduino Nanos and Arduino Unos. Kevin (@diyelectromusic) has created special components for synthesizing different instruments and breaks down the construction of each one in this blog post.

The Pico creates visual output using a Pimoroni Unicorn Pack—a module consisting of a small, programmable matrix of LEDs. This isn’t the first Pico Kevin (@diyelectromusic) has tinkered with as we also stumbled across this Pico-based multi MIDI router.

To see this project in action, check out the demo video shared to YouTube and be sure to follow Kevin (@diyelectromusic) for future musical creations.
