I created an amplitude modulation patch and a ring modulation patch.
The amplitude modulation patch is basically for modulating oscillators that process a carrier in series one after the other.
My second patch (pictured) uses three oscillator. In each "iteration", the three possible combinations of two signals are ring modulated, and three new signals are created. The process is performed 8 times, however there is rarely much signal left at this point. An iteration selector fades between the 8 different stages so you can dynamically move from slight modulation to grainy noise. The 3 outputs can be individually panned to create a true rich stereo signal where the different channels are different but related.
I wasn't very successful in creating organic sounds, however many types of rich machine sounds were easily accessible. An engine noise from this patch should be usable for the major project. Putting noise through the system created some interesting buffeting wind. The stereo output should be useful in a soundscape.
