MOTM

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.
