If you have ReaTrak put these files in the Scripts\ReaTrak folder
else put them in your \Scripts folder
then load the "ReaTrak region chords to 4-4 jazz swing midi.lua"
in the Action list window.

mjb2lite will generate up a jazz swing midi to your chords (region and name) and tempo.
You need a 2 bar count-in region RGB color 255,128,192

The part markers to change from verse A to chorus B are region RGB color
dark blue 17,39,174
dark green 11,116,39

to set the ending verse ending A or chorus ending B are region RGB color
light blue 151,208,254
light green 158,245,182

you can try some sample region chords csv here:
https://www.reatrak.com/downloads/test_files/templates/
load one in the region manager, set the tempo then run the script,

It can be modified to work on Mac if you have Wine,
in the Terminal it will use this command to get the Windows CMD Prompt:
