Thanks so much! It does indeed answer my question. I
also got a very good answer from Larry (shown below).
It seems I probably need both solutions - a simple
attenuation (read: home-made panel with a bunch of
pots) and maybe some additional VCAs..
Thanks again,
Dino

I would not modify the output of my 380. You have
better options. If
you
are just using the VCA as a static attenuator (i.e. no
voltage control
of
the modulation amount) you have two other good
options.
1. You can change one resistor in the MOTM-300 which
will change the
gain
of the FM circuit. So, the of 0-10 could be the
equivalent of say 0-5
or
even less.
2. You could use a mixer to attenuate the sound. Or a
reversing
attenuator
(like the Oakley multimix)
3. You could build a simple passive attenuator for
this made from a
single
pot and 2 jacks.
