Rousseau-inspired Raspberry Pi Zero LED piano visualiser
Unlock your inner Rousseau with this gorgeous Raspberry Pi Zero LED piano visualiser.
Fans of the popular YouTube pianist Rousseau would be forgiven for thinking the thumbnail above is of one of his videos. It’s actually of a Raspberry Pi build by Aleksander Evening, who posted this project on Reddit last week as an homage to Rousseau, who is one of his favourite YouTubers.
Building an LED piano visualiser
After connecting the LED strip to the Raspberry Pi Zero W, and setting up the Pi as a Bluetooth MIDI host, Aleksander was almost good to go. There was just one thing standing in his way…
He wanted to use the Synthesia software for visualisations, and, unmodified, this software doesn’t support the MIDI files Aleksander planned to incorporate. Luckily, he found the workaround:
As of today Synthesia doesn’t support MIDI via Bluetooth, it should be added in next update. There is official workaround: you have to replace dll file. You also have to enable light support in Synthesia. In Visualizer settings you have to change “input” to RPI Bluetooth. After that when learning new song next-to-play keys will be illuminated in corresponding colors, blue for left hand and green for right hand.
The final piece is a gorgeous mix of LEDs, sound, and animation — worthy of the project’s inspiration.
Find more information, including parts, links to the code, and build instructions, on Aleksander’s GitHub repo. And as always, if you build your own, or if you’ve created a Raspberry Pi project in honour of your favourite musician, artist, or YouTuber, we’d love to see it in the comments below.
And now, a little something from Rousseau:
