I did a search online to see if there was a way to make certain Kontakt instruments extend their playable range even if just a bit and obviously with faked sound, but just to use in a few occasions here and there. So I came up with a Reddit post from 10 years ago:
You click on the wrench key at the top left of your instrument window, then mapping editor, then drag the mouse across all the samples on the grid to select em (they will turn yellow) then right click, automap functions, auto-spread zone key ranges.
So I said great, let's try it. And I did extend the range visually that way, but the range stayed the same when I play the lower notes (which is just 3 semitones lower than C1 since it's a cello), nothing happens. I can play down to C1, the original range of the instrument, but B0, A#0 and A0 produce no sound.
Is there a step I'm missing?
