My song is already big, so I don't want to use additional space with the $FA $03 command. The tool helps enormously though, because I get the y value and can calculate the v value at least approximately by adding the $FA $03 $XX factor (if it's a linear function).
What is the default value of wXXX anyway if you don't set it yourself? I would estimate it somewhere around w200.
$FA $03 is a linear volume multiplier, whereas v and w are exponential.
AMK uses the following formula for it:
(computedvolume * volumemultipier / $100)
This means that $FF roughly doubles your output, but in dB it won't be twice as loud, whereas with v and w that should be roughly equivalent.
