Some of the circuits shown at the A-100 DIY page can be used for this
application, e.g. the non-inverting amplifier or the inverting amplifier
(both for amplification only), or the CV mixer with offset function
(adjustable offset and amplification). With suitable values for the
resistors all these adaptions can be realized. If you want to reduce the
work you may use an A-138 and replace the existing resistors by other ones.
The CV mixer with offset function is nothing but the A-138.
