1. Once again JWB is only 1/2 right <stooge snicker>.  I'll go with Dave
here "prefer the latter" that the "UP Rate and DOWN Rate" pots remain
offset level and jax unattenuated.  At some point we have to say "OK, I
need a reversing attenuator" as a separate module so that every single
module that Paul makes does not have to have DC attenuation as part of the
design.  I can't see two pots on every MOTM module DC input, one for
initial and one for attenuation.

2. Now, to argue with myself (since I know everyone else will chime in
too).  Looking at the former MOTM modules (like the 410 for example) it
seems that initial pots do become attenuators once a CV in inserted.  so,
maybe from a consistency of application, that is the right answer (Dave
said it was a close call).

3. Now, to support John's weak argument, some VC inputs do deserve BOTH
attenuation and initial (PWM on the VCO).

I think an argument can be made for any of the three. If I had to pick, 3
would be the most control assuming the two extra pots don't expand the size
(knowing they will already significantly expand the cost).  However,
picking between 1 and 2 I would go with Dave B's close call and pick # 1.

Since John may feel picked on right now, I like the idea that the single UP
& DOWN pot is a reverse attenuator CV when CV source is plugged.
