Densest ear-feedback session logged so far, and the finding that makes it worth
re-reading: not one of PLN's 'it sounds wrong' reactions was a mix problem.

  'muffed'      -> a SynthDef's own 1 kHz Moog lowpass, no cut group, shared bus
  'loud'        -> SuperDirt amplitude is gain^4, so `# gain 2` is +24.1 dB
  'irritating'  -> a literal ascending scale being used as a melody
  'no buttons'  -> CCs that were never mapped
  'weak'        -> the one track the column remap never reached

Includes the gain->dB table and the measured claim that the OPAL set's median
orbit sits at +11.7 dB while four sit at +24.1 dB — and the rule that follows:
when an orbit clips, rank the track's orbits in dB before touching a fader. A
10 dB intra-track outlier is a bug; 2 dB is a mix choice. Feeds #91 and #17.
