Harmonic Crossfader for Kontakt 2.1

Hi everyone,
I've developed a midi controlled script for Kontakt 2.1 that crossfades microtuned samples against up to eight specified harmonics on sine and scalable cosine fade/rise curves. I think it gives Kontakt a bit of a JI afterburner...

You can check it out, along with an upgraded Scala 2 Kontakt Microtuner at http://www.12equalboresme.com

Robert Strauss

I'm afraid I don't understand what it does...

But it does look like, thank to your script, Kontakt is the
tool of choice for microtonal music with samples.

Carl,
A little more technically, the Crossfader script plays a microtuned sample note and up to eight simultaneous instances of the note. From
the UI, the pitch of each of the eight instances can be set to a
rational fraction relative to the original note. Rather than just
play a 'wall' of these harmonics, the script tracks the instantaneous
value of a specified midi cc channel to set the overall mix of
original note and harmonic clones. From listening to crossfades where
the sounding note moves from all fundamental to all harmonic, I
realized that linear fades tend to have an annoying volume dip as the
relative volumes of fundamental and harmonics cross, so I switched to
a cosine/sine model that gives a more constant volume.

Like any effect, it can be tedious if overused, but the ability to
control simultaneous clone notes in Kontakt is an interesting feature for a sampler. Next up, I'll work on a microtonal constrain-to-scale
version that models sympathetic resonance. Thanks for your interest,
Robert

Gotcha!

That would be cool!

Speaking along these lines, do you know of any way to retune the
partials of a Kontakt sample (I don't suppose they're tagged in
the sample)? Perhaps the only way is to record a sound which has
tempered partials...?

-Carl

Kontakt doesn't currently offer any way to directly manipulate the
partials of a sample. If there is some tool from the additive
synthesis world to explode a sample into files for groupings of
partials, I think Kontakt could take it from there... Its something
to look into - thanks for idea!

Perhaps one could sample a sine wave and use your crossfader tool...
