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.

Cheers,
Ralf


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.
