Enhanced Amplitude Modulation
With this effect you can modulate the Amplitude of a source signal with a modulator audio signal. It's a little bit like a vocoder for Amplitude Modulation. It makes sense in diferent ways. You can use it for dynamics by letting a drumloop make your synthpads more rhytmic for example. or you can let noise signals make sounds more clicky...so more the experimental way.
I guess you have to twiddle around a bit to get something useful out of it so I uploaded an example ensemble. Just start by trying out the fx-mix knobs to hear the actual effect on the source signal.
