Toggling a color inversion or hard posterize on the drop downbeat is a single-frame visual hit

The invert/posterize snap is triggered on a hard accent — the same downbeat as an audio drop — to give a single-frame visual hit. A color inversion, a hard posterize, or a luminance threshold is toggled on for one cycle for a stab, or held longer to change the whole section’s look. Because it is a single decisive toggle timed to the accent, it reads as a hit rather than a gradual change, and it pairs directly with the silence-then-hit audio drop on the same downbeat.

Examples

src(o0).invert(1).out() snaps to a negative image; remove the .invert on the next save to release. Substitute .posterize(3) for banding or .thresh(0.5) for a hard black/white flash.

Assessment

What makes the invert/posterize snap read as a hit rather than a gradual change? How does holding it versus keeping it to one cycle change its role?
