"Polyphonic key mode" in settings

I get an extra message when I click on the Retrologue 2 settings (gearing) icon:
“Polyphonic Key mode”
see attached picture:


What is the meaning/use of this line ? Nothing in the manual…
And btw (talking about mono/poly) you can’t assign a MIDI CC for the first 2 “buttons” Mono and Retrigger (no context-dependent menu on right click), but that’s another issue…

they have it explained in the version history pdf i guess they need to update the manual

it says Polyphonic Key Mode allows to start and end one and the same note
multiple times independently. If activated, ending one of the notes will not
end the others.

Ah! Thank you.
