This Preset only works with 128 bands - click settings and set FFT to 128 (reload zge). Depending on your PC, real time preview might run at lower frame rate than the actual rendered export.
A preset I created - Just an LED board - you can edit the LED in the zgameditor. I haven't programed anything else to the LED yet, but might do some more with it later.
The song "Monolithic Filter" by FL Studio Guru - "Scott Fisher": in Projects/ Cool stuff, demonstrates filter automation in FL Studio.
