Changing the range to get the bottom end lower (it could never

There is one possible solution I can think of, but I'd want opinions from
others first.
This would be to completely bypass the part if the volume control was
set below
(say) -39.9dB
As a point of interest there was a related problem we solved several
years ago.
This was when the cutoff for fading note tails was -40dB as well. You
could
distinctly hear the end of a slow decay with no effects or other notes
sounding.
In that case we just changed it to -60dB
Thank you for this information Will. This is good news! Of course you
are to "bypass the part if the volume control was set below say -39.9dB".
However, the midi signal volume resolution is quite low (0...127)? Maybe
I am wrong, but to play safe, should an optimum threshold level be
checked in practice before freezing it to the master?
