The A6 allows an extremely deep index of
exponential FM on the oscillators and filters
as well, far greater than on the MKS80 (I've
had a couple of those as well). The VCAs
which control this amount, along with the
VCAs which control the amount of external
modulation of oscillator frequency, filter
frequency etc. are not calibrated, as you've
found; I don't remember the specific reason
why, but there it is; you should be able to
duplicate what can be done on the MKS80
with the A6 if you use the FM sparingly.
An issue way down the wish list would be
to see if these parameters could be hand
set in some sort of sub-menu; it is unknown
if they would have to be tuned after each
power-up (by hand, again).

Analog is, well, analog. Digital offers
perfect tracking and pitch stability (with
the resultant precise FM) for those who
need it. It has yet to be demonstrated
that virtual digital systems can produce
the organic character of musically-oriented
gear.
