hi all,
wondering if anyone can explain the autoning process and the storage of tuning tables to me (the service manual is pretty helpful, but this pertains to the issue below).
Basically,
after having not had to tune my M12 for months, I suddenly found a few
voices slightly out of tune yesterday. I attributed this to recent
weather and autotuning cured it. But then I hit "untune" (just to see
how "out" everything really was) and had to go through the whole tuning
process again. (the only recent "change" was that I rotated out some
3372s under the hood, but the 3374s were untouched.)
Jump forward
to today, turning on this morning, I found a couple of voices were
beating more than the others. After it had warmed up for a while, I
began hitting autotune until all voices were yielding pretty much no
significant beating. That tuning has now been fine for the rest of the
day.
So getting back to my initial question: does it make sense
for the autotune tuning tables to improve their accuracy with increased
time (and also after full warmup)? Obviously there's no "background"
tuning, but the voices seem to have improved stability overall through
the day. Given that my need to tune yesterday was a bit of a surprise,
I'm just wondering if there's some creeping issue I should be aware of,
or if this sounds normal.
I should add that this was recapped fairly recently, so I don't suspect anything there.
