Dear Dieter Doepfer,
I'm facing many situations were it could be useful to have a simple mixer with only two inputs. Dry/wet mix, adding another CV to a VCA or a VCF, mixing only two VCO ...
A dual module with a layout similar to the A-133 or A-132-3 would be so cool.
A lin/exp switch and another one for bipolar operation
Some alternate behaviour to scale (offset, reverse) a signal when there's only one input in use
Cheers,
Pierre
