Well that got me thinking!
Presumably this should be set up as a proper log law, so even if the steps
represent (say) 0.5dB that still gives a control range of over 60dB

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
So Allen & Heath uses 127 levels on their top
end digital control
surfaces, How do they do it? Well they have two different scales:
- fader: ((Gain+54)/64)*7f - also used for sends
- Gain: ((Gain-10)/55)*7f - this is preamp gain
Suppose you have *real* faders which have a range of 127 mm.
That's not far from a typical size on a pro mixer.
Would you ever adjust them by half a millimeter ?
127 steps, provided they are mapped well, and zipper noise
is avoided by interpolation or filtering, should be enough.
The real problem is that many SW mixers
* don't use a good mapping,
* and don't have any other gain controls.
The latter may force you to use the fader in a range
where it has bigger steps.
