.......well you seem to have it right so far :)

there is a ckt with 1 op amp that allows gain to go from -1 
when fully anticlock to +1 when fully clock. I have used this
for envelope depth control in pedals with not enough space
on the surface for an inverting switch

It is in Horowitz and Hill, also Jung's Op Amps book.
