See the mail I just sent.  I don't dislike logarithmic mappings, and I
have no idea what various users prefer.  What I dislike are showing dB
values in the software, because you can't guarantee that that is
actually the loudness level that the user is hearing (explained in more
detail in the mail I just sent).

Which seems like something we want, right? :-)

Any software that doesn't use a dB scale treats you like an idiot?  So
any user that either doesn't understand -- or want -- a dB scale is an
idiot?

That's too bad.  I was really looking forward to your remapping patch.
