We can always use Native Instruments built-in effects with other instruments and I am going to show you how to use Native Instruments Komplete Plugins as FX in Ableton Live.
Let's say I'm working with Analog and I want to use 'Psyche-Delay from NI FM8 synthesizer.
I can load FM8 FX right after the instrument, make a change in the patch, so it can process the incoming signal.
Next, I'll add ´Psyche-Delay' from the effects page.
This way I'm processing Analog through FM8's effects.
This is possible with most of the Native Instruments' Instruments including Absynth, FM8, Kontakt and Reaktor.
