Korg had an ordinary HADSR in the MS-20 that had a normal output
(hard wired to VCA) and a "Sustain biased" output (patchable). This
is easy to implement (subtract sustain value), but *not* the same
as in the Yamaha synths.
In the Korg version, decreasing the Modulation Amount means decreasing
both AD and AR parts. And decreasing Sustain meains increasing AD
and decreasing AR.
In the Yamaha version, you can alter the AD and AR amount independently.
This is easy to implement as well, but not easy to derive from a standard
ADSR.
