If you don't have AutoHotKey install it https://www.autohotkey.com/

Remove .mp4 Biab-Actions-Metronome-Record-Chords.zip.mp4
and unzip it then run it
enter the initial chord on your keyboard that you have set as midi input device
set Biab to the bar where you want to start recording the chords
click "Record Chords"
it will record up to 2 chords per bar.

Let me know if it works okay or the timing needs adjusting as I don't have a keyboard at the moment.
It should still also work with menu > Window > MIDI Chord Detection
open if you want it there.
It uses the system audio so you may need to release the ASIO driver in the Driver Setting.
