If all you want to know is the output then the RCX will display that - using
the View button to show the sensor input you're interested in. If you want
to play pretty noises the only alternative I can think of (and this is ugly)
is along the lines of
if (IN_1 == 1)
{
PlaySound(1);
}
else if (IN_1 == 2)
{
PlaySound(2);
}
etc.
Obviously you wouldn't want to do this for every value from 0 to 1000, or
whatever, but you might do it in bands 0-100, 100-200, etc. and you could
write this in a subroutine.
Equally obviously, you'd rather have a switch statement, but NQC doesn't.
(NQC still gets my vote, though.)

The answer I got was "its a firmware thing" -- not that its much of
a
helpful answer (to me or to you). A while ago I was really hoping
to be
able to do the same thing... especially since setting the motor
speed to be
dependent on the light sensor doesn't produce an easily visible
feedback
since the new motors don't seem to change speed much. I ended up
using a
lego lamp for the experiment instead.
