midiviz-prepare
is a MIDI file pre-processor for MIDIVisualizer.
Background
- Once upon a time, there was a great utility called MIDIVisualizer, by @kosua20.
- At some point, @ekuiter has decided that we need a fork of this app. He has pulled the trigger. Then he has added various enhancements, but alas he also
broke modified one of the nifty features of the original app. The original app was able to color major and minor keys differently. The forked version uses the coloring to indicate different tracks, which is not very helpful when there is only one track. - So I was faced with a dilemma: use the original app, with the nice coloring, or use the new fork, with the fancy features:
Solution
My answer is that I choose both. I need the fancy new features, and the correct coloring.
One possible way to achieve this would have been to create yet another fork of the project, picking and choosing what I want from both versions.
But I didn't want to further fragment the already split landscape of the code. Also it would have been a PITA to maintain this version later on.
So instead of that, I just created a small MIDI pre-processor utility, which is able to move the minor keys to a separate track, and thus achieve the desired coloring with the new version.
