Capability gene

CAGENE:MIDI-SCHEDULING

MIDI Scheduling

Decides when an incoming MIDI event becomes an audible note. Owns the buffering strategy that trades input latency against dropout risk.

First observed in KEYLIT at commit:27ad9016b4 on 2026-08-28, with origin confidence 1.00. That confidence is about the claim of where the capability started, not about the quality of the code.

Allele lineage

Each allele is a variant of the same capability. Select one for its own record, or compare two to see exactly where they diverge.

Adaptive buffer

CAALLELE:MIDI-SCHEDULING:5

Measures jitter continuously and resizes the buffer in flight. Cuts median latency by 22 ms without new dropouts.

A gene here is a capability, not a file. “MIDI Scheduling” is the thing that persists; the paths under Loci are where it currently lives and can change without the capability changing. Every figure on this page is read from the seeded KEYLIT fixtures.
