Hi Nick :)
the Roland MT-32 (don't judge it because of the factory presets) is
using less than 100 steps, the Oberheim Matrix-1000 is using 7bit, the
Yamaha TG33 and Yamaha DX7 don't have filters and I don't have any other
manual ready to hand right now. I don't have any issues because of the
tuning when using the MT-32 or Matrix-1000.
IMO for virtual synth more important than automation would be a more CME
microchips similar sound.

PS:
This reminds me to make a test. I've got an original DX7 in the brown
metal case, one of the first ever released without any software update,
but I know someone having a DX7 II in a black metal case and I like to
compare the DX7 II with Hexter. Hexter completely has nothing to do with
a DX7 in the brown metal case, but for the sounds I heard on the DX7 II
I had the impression that those might be comparable to Hexter. Anyway,
the really important issue for soft synth is, that nobody ever was able
to emulate CME microchips. Some days ago I played a Nord Lead virtual
analog synth and it was relatively good. But even people like Dave Smith
be less fond of virtual synth. I've got no time to scroogle for Dave
Smith now, but I'm sure there are some interesting links in the web,
because of issues for virtual synth and "real" synth.
For filters etc. most times just 128 steps are
enough, hardware synth
tend to use just 128 steps even when using SysEx instead of CC.
Just 128 steps for filter cutoff for an oscillating emphasis does not
work well
if it needs to be tuned exactly to an VCO/DCO, it is basically never
in tune
and was a big grumble about the early programable analogues since they
only had 64 to 128 steps available for filter frequency from their AD
control
converters and memories. Two bytes does go a long way towards the goal and
it pretty much on if it is not applied as literal Hz but as a power scale.
Somebody asked which soft synths would support this kind of feature,
Bristol
will be implementing CV in the next release for subset of its emulators.
