For those not using MIDI (which I believe is the case of most PD users),
midi-dB is not that intuitive... And I don't see any reference about
midi-dB in Miller's book. I can believe that midi-dB is handy and make
sense, but I used MIDI and I don't understand your explanation (and the
conversion pseudo code).
If 128 values are used to control a 0-100 dB range, it means that the
midi-dB resolution is 0.78 dB. For 16 bits audio, the range is 0-96 dB, so
the midi-dB resolution is 0.75. For 24 bits audio, the range is 0-144 dB,
so the midi-dB resolution is 1.125 dB. Is that correct?
