Multiple tempos / BPMs about midi HOT 6 CLOSED

I don't speak for @tambien, so I have no idea if this is somewhere he's interested in taking it. I will say that PRs are more likely to be addressed than feature requests. 😃

@Topograph I figured out how to build using the commits from that thread in the end and the output result does match your version so I guess they both are the same. Thanks anyway! :)

I also have problems with tracks including tempochanges...not sure how i can solve those

Edit: Nevermind. I found the duplicate thread of this one. And took the modified version from there....did the trick for me

@Topograph Hey, do you mind sharing the relevant bits of code? Feels cluttered in that thread with all the commits.

Hi,
It's been a while. I only found this one on my hard drive:
MidiConvertTime.js.txt
(rename the txt file to .js, GitHub seems to only allow certain file types in here ;). )

This seems to be a minified version. Sorry I found no other.
If I remember correctly this version considers the tempo changes when calculating the durations and starting timings in milliseconds of the notes.

should be fixed in the latest release. i compare all of the tempo changed timings against output i generated from pretty_midi, so i'm pretty sure they're accurate. the tempos are stored in an array of tempo events in the header file. if this array is modified, you have to update all of the note and cc time values by calling midi.header.update().
