This is the first real “thing” I’ve created using MetaSynth as I go through the extensive tutorials.
This was the result of (somewhat haphazardly) drawing & sculpting pixels in the ImageSynth and then playing with different harmonic tunings for the pixels.
I did round trip the image briefly through Acorn (an image editor) to apply a Lenticular Halo effect which is where most of the high-frequency sounds come from. I also applied a couple of MetaSynths image filters to pan the sound around.
I exported a few copies of the resulting loop and applied a fade-out in Fission.
