Hello, This is my first post.
When I import a midi file, I was asked whether I would want to CLEAN UP the imported project. Please explain what it does. I was also asked if I would like to do it manually, but I don’t know what a “clean” midi should be.
It will extend some notes to fill extremely short gaps, as well as removing overlapping notes.
It might also remove invalid zero-length notes which would end up invisible in the SynthV piano roll, but I can’t confirm this because my DAW doesn’t export these “ghost” notes that some other users have encountered.
For example, this is a “messy” MIDI file I threw together to test:
This is the automatically “cleaned up” result. Note that it removed many of the overlapping notes, shortened some to fill gaps, and bridged a small silence toward the end.
When overlapping MIDI notes start at the exact same time, the one that remains will the be the last one encoded in the file.
