This module has proven more useful than I imagined. The division into A and B channels is brilliant, but the master out lets it also be used as eight singles. The (undocumented) normaling of inputs from A over to B gives it added potential use as a place to convert any single mono into separate left(A) and right(B) outs. The inverted output on A gives it great CV mixing potential. I'm currently sending the A output to another mixer and B output to an effect unit before it goes to the other mixer, allowing me to control the dry(A) or wet(B) amount of signal in my final mix. This is a swiss-army knife module that you wight want to get a couple of. And, it is inexpensive and well built!
