Other the bell mechanical
the diogenes filter [disquiet0291]

Took this quite literally. Looked at the spectrum of LED warm indoor house lighting. That in Hz is roughly E-flat/D-sharp. Made several pad/deep flute drones in that tone.

The "ribs" of the lantern housing is a comb filter.

The 'ambient glow': shimmery delays/reverbs, focused on the core tone.
