Actually, this got me thinking about the odd volume scaling on the ADSR
envelope in the instrument designer. If you set the Sustain of an instrument
to 100%, it's at max volume, but if you put it down to 90%, it seems to drop
a LOT more than 10% of the volume - in fact, it goes nearly silent. It seems
that the entire range of volume is covered in the 90-100% and if you want to
tweak the level, you've got to try things like "98%", "97%" etc. which seem
to be a lot different just within that one percent. And anything under 90%
is just quiet. Well almost.
Anybody else find this a bit odd?
