midi export loses tempo messages

[bachworks]

Why doesn't lmms include tempo messages in exported midi files?

When I import midi the tempo track comes in as it should. Exporting should include tempo track.

I use tempo-track editing to create rubato, rallentando, and so on. In detail. Down at sixteenth-note resolution, sometime several tempo shifts per measure.

Am I missing something?

You mean in the MIDI-export- Right?
Unfortunately MIDI-file export is flawed. There are some issues, that make lmms export several or all tracks into only one track.
Atm our midi-export does not work

Thanks for your speedy reply. Based on what I found in some related threads here, the news is approximately what I expected.

Are there any plans to fix the midi-export shortcomings, such as they are? I have some decades of software experience and might be able to help... .

Background: I'm resuming a project that I abandoned fifteen years ago. The sequencer I used at that time was Sonar3, on Windows XP; it gave me all the control I wanted, even a rudimentary macro language for scripted editing of my midi sequences and all of their musical parameters. I'm prowling for something similar today -- on linux -- but haven't identified anything yet.

I can use LMMS even with the hobbled midi-export behavior, but it complicates my workflow. It would be really nice to wake up some morning and find the problem gone.
