MOTM

As most of you have probably noticed, three of the outputs of the
MOTM-320 are 10Vpp, and the saw output is 5Vpp going from just above
ground to 5V.  While it does make the saw output more useful when
driving pedal inputs and other devices that don't like negative
voltages (as you can also change it to a more useful triangular
shape), it does make it is inconsistent with the other MOTM-320
outputs when used within the modular.  This makes its effect when
switching from another output not only a change the shape of the
modulation, but also half the range.

I'm not sure why it was designed that way, but is there an easy way
to change the saw output to a bipolar 10Vpp output?  It doesn't look
like there is, but I could be missing something.  So I thought I
would ask before I built a daughterboard.  Any ideas??
