The "type" is irrelevant, the problem is that what I generally want to say
is "this goes from 0Hz to fs/2Hz, and I want it to be logarithmic", but
you can't say that literally, so you have to say "this goes from
fs/10000Hz to fs/2Hz", which tends to make the bottom value a bit random.
I don't know what the correct solution is, possibly just providing a rule
for the host to caluculate what it should use instead of log(0) is enough,
but I'm not sure what the rule should be.
I can't imagine any sane interface standard
for audio controls without a
way to say that the natural way to represent a port's range is exponential.
saying that the port range is exponential doesn't pin it down very much.
it still requires the host to make decisions about precisely what kind
of exponential curve to use for the range, and it may get it wrong. The reason why
it gets them wrong is probably
because the code handling defaults is something like 10 times more
complicated than it need be.
care to suggest a simpler approach?
