Parabolic LFO shaper

Another simple marcos which I’m going to use hard is Parabolic LFO shaper. There is “Parabol” shaping module in build-in Reaktor libary, but “as-is” module produces one-side parabol shaping (you can’t mirror the parabolic shaping). There is a small addition that makes possible two-side parabolic shaping. Another fundamental thing in my synths.

• in – input signal to be shaped, range: 0 to +1
• out – output of the shaped signal, range: 0 to +1
• Parabol knob – distortion amount, range -1 to +1, 0 means no distortion.

There are example pictures:

No parabolic distortion, sin and saw:

Parabolic distortion (+1 at “parabol” knob):

Parabolic distortion (-1 at “parabol” knob):

The shaping amount can be easy doubled by simple duplicating the parabol module:

And here is the macro file.
