I always wanted a Roland A110 MIDI note analyzer but never got around to buying one just for the novelty value, but now they are ridiculous money and rare as hens teeth so I set about making my own

This is Teensy 4.1 based and uses 10 SPI SSD1306 0.96" 128x64 displays to show 10 octaves of notes

that's very nice.

I didn't immediately recognize the screens and started to wonder how you made the panel for the LEDs Laughing

Many thanks, it was hard to actually build a suitable display, i2c was too slow and I had to go with SPI for speed, I couldn't find anything else suitable for mounting into a 1U case, I would have preferred colour screens but I could find anything edge to edge so I could put them up against each other to try and make a contiguous display.
