Here is something I have been wanting to do for years.
Due to the pandemic, I have been basically under house arrest for the last two months so finally got to it.
The project was adding MIDI to a nickelodeon and then getting it to communicate to a 1918 Mills Violano so the two would play together. This little project turned out to be a lot more involved than I anticipated but I finally get it done.
