Description

Not sure if this is a bug report or a feature request but if you have an automation track changing the tempo of a composition, the exported MIDI file will not carry with it the appropriate MIDI tempo change event.

I imagine automation is entirely disregarded during the export process but considering MIDI supports a tempo change event, it might be relatively simple to support this particular feature (maybe even through a hack that keeps track if the tempo has changed since the last beat or something).

Thanks for the amazing work on LMMS! As if it wasn't already my music production suite of choice, you guys keep making it even better! The MIDI export is godly!

Research direction

No file or test entry point is named. Start by locating the MIDI export path and the tempo automation handling; done means exported MIDI files contain tempo change events that match the composition's tempo automation.
