Longstanding thing...
REAPER needs at least 2 tempo Events within the project(Start & End of the project) for export..........
And the same refers for importing midi files!!!
REAPER never ever import other tempos as the standard 120BPM
(which dont need of course an TEMPO Event) if these Files
only include 1 TEMPO Event-which is pretty
the Standard for MIDI Files if there is only one global tempo others than 120..
like for example 100BPM 4/4
1: 1: 0 |Time Sig|4/4|MIDI-clocks\click=24|32nds\quarter=8
|Tempo|BPM=100|micros\quarter=600000

REAPER is too stupid and need this:
1: 1: 0 |Time Sig|4/4|MIDI-clocks\click=24|32nds\quarter=8
|Tempo| BPM=100|micros\quarter=600000
5: 1: 0 |Tempo| BPM=100|micros\quarter=600000

REAPER ignore or better dont know about files with one global Tempo Event.
Another thing that makes me-..xxxx
REAPER ignore already included TRACK NAME Events.
If you often enough export the same tracks again (without to first delete the TRACK NAME Events)
there can be hundreds of TRACK Names for the same Track at the same 1:1:0
REAPER always added his Export NAME to the TRACK as Track NAME Event
no matter if there is already one name... for the Track.
What stupid.
