Detailed level rides on individual notes and syllables beat any static fader

Static faders cannot follow the fine, perceptually complex level variation within a performance, and keyed dynamics act on amplitude, not perception, so complex masking (a note lost not because it is quiet but because it sits in a frequency gap) resists them. Only manual rides evaluated by ear — often best judged on an Auratone at low volume, from quarter-dB nudges to momentary 6 dB lifts — compensate for these interactions.

Examples

In a dense guitar arrangement, certain bass notes get lost though they are not quiet; compression will not level them, so the engineer rides those notes up by ear.

Assessment

Explain why manual rides are essential for complex masking compensation that keyed dynamics cannot solve.
