Prelude in Color, an exercise in visualizing Bach's Prelude No. 1 in C Major from The Well-Tempered Clavier with the help of the color spectrum.
There are 2 Raspberry Pi's involved. A Raspberry Pi 400 is capturing the MIDI and rendering the Steingraeber E-272 from Pianoteq 8.
The first Pi is also rebroadcasting the input MIDI wirelessly via rtpmidi to a Raspberry Pi Zero W. That second Raspberry Pi is running Piano LED Visualizer for the LED effects.
I'm also using MIDI Visualizer by Simon Rodriguez.
Honestly, there's so much more work I put into this, I can't even remember it all.
I didn't want to go the route of a harpsichord, but I feel the Steingraeber E-272 from Pianoteq 8 served me well here. It's a very pure sound.
At the very end of the project, I was having serious misgivings on my Bach rendition, but after a day's worth of pondering, I figured it is what it is.
