I have been working on MIDI animations for about 10 years now, using various methods. I was inspired by Steven Malinowski's Youtube channel. (Smalin.) Apart from him, there was no source whatsoever where I could learn even the first things about making MIDI animations. It just began by thinking how to promote my music through animations. It took me a long time to even understand the first principles of making such animations. I remember I was thinking about his animations, which are almost all 2D, and I wanted to know what to do to just show part of the song. I learned later that this was called: 'the culling' problem. Then I looked at one song in particular of Bach,m where the entire base consisted of just two notes, everything else happening on top of it. it then dawned on me, that there could be songs where the entire base consisted of just one note-on and one note-off. This made me conclude that, to make animations like that of Stephen Malinowski, one should make a picture of the whole song in each frame, and just 'shift' it. I then discovered that that, indeed, was how Stephen Malinowski began. Then I saw the videos of Andy Fillebrown on his Youtube channel: Andy Fillebrown, and that inspired me to tro to do what he did. Strangely enough, in all the years I have been experimenting with MIDI animations, the biggest hurdle was the MIDI file itself. How to parse a MIDI file, when you just have the binary file? In my attempts to solved that problem I have learned a lot about computer programming. And, thanks to the latest version of ChatGPT-o1 and ChatGPT-o1 mini I now have MIDI parsers for Python, C# and C++. I tried to do it with ChatGPT-4o, but that, very surprisingly, failed! The problem was always the tempo track. The simplest way to use MIDI in Blender is through Animation Nodes, which has a MIDI-file script node. And the second best way is through a python library called mido. But it is a little hassle to install that in Blender. That is why I am now working on a MIDI file plugin for Blender which does not use any external libraries, so that I can just distribute that on Blender Market.
