MMix (fade 1/2 by 3xC)

[kontakt]

Hello.

"MMix (fade 1/2 by 3xC)", this has been bugging me forever...

About the case to input the bipolar source(ex. pitchbend wheel) to Mod3...

I think...(if Const = 100)

(only -Mod2) <---(-Mod1 -Mod2 )<---[Center(only Mod1)]--->(Mod1 + Mod2)--->(only Mod2)

But the result...(if Const = 100)

(Mod1 -Mod2(100%)) <---(Mod1 -Mod2(50%) )<---[Center(only Mod1)]--->(Mod1+Mod2)--->(only Mod2)

How should I think about?

How should I think about?

Actually (using your notation), the result appears to be:

(Mod1(200%) -Mod2(100%)) <---(Mod1(150%) -Mod2(50%) )<---[Center(only Mod1)]--->(Mod1(50%)+Mod2(50%)--->(only Mod2(100%))

i.e. more clearly:

Fully negative : Mod1 = 200%, Mod2 = -100%
Half Negative : Mod1 = 150%, Mod2 = -50%
Center : Mod1 = 100%, Mod2 = 0%
Half Positive : Mod1 = 50%, Mod2 = 50%
Fully Positive : Mod1 = 0%, Mod2 = 100%

Still experimenting - interesting observation, kontakt!

Howard, Thank you very much!

I think...


I tried to experiment again.

My settings...


(with Spectrum Analyzer / FMO1 = pure sinewave)

The results seem to red line...

I think...

If I'm interpreting your diagrams corrently, this one shows my result, i.e. that Mod1 is +200% when Mod3 is fully negative (and C is 100% of course). Right?

The results seem to red line...

That's your original finding, and I think it's wrong. The simple test is: Mod1 = square LFO, Mod2 is empty, Mod3 is Pitchbender, target is pitch of any oscillator. If your "red line" was correct, pitchbend down wouldn't change anything, but it does.

I had the square LFO doing an octave when Pitchbender was in the centre. Pulled down, it became 2 octaves. Hence 200%.

I just understood.
Cause of my mistake was that the amplitude of the modulator is too large...

Zebra is by far the best synth I've ever used.
I will make a lot of good music with zebra.
Thanks again for your time.

Thanks for your very interesting observation, kontakt!
