"auto-spread zone key ranges" how to apply edits?

ProfessorChaos

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?

Hello.

It should normally work, do all notes not work to spread or just the lowest and highest? Then maybe extend them manually. Another option could be to use creator tools, it has a build in analyzer for pitch and adds the samples automatically to the correct key and so on. It can be useful to just use creator tools for this purpose.

Well, what happens is that it doesn't create new notes, now that I had a choice to take a better look at it. What it does, at least when I follow those instructions, is that it extends the lowest note, C1 all the way down to C-2, and the highest note, C4, all the way to G8:

However, nothing plays below C1 or above C4. Also, Kontakt is practically useless when I go into that mode. I have a Mac Studio Ultra M1 and it feels like a Commodore 64. Everything is delayed 1 or 2 seconds.

Thanks for the other tip, I'll try that as soon as I get a chance.

Maybe you just edit one layer/group of that instrument, i don´t know that particular one. some sounds have different samples for the attack - sustain and release phase for example and if you just stretch the octaves, you can play, for one layer it won´t work as you expect.

That's what autospread does.

It's probably a script which is preventing you extending the range. There is a simple workaround:

1. Adjust the tuning (instrument header) by however many semitones you need.
2. Adjust MIDI Transpose (Instrument Options>Instrument) by the same amount in the opposite direction.
