I managed to get an A-126, but it seems to be broken. The only knob that does something is the level knob, and I have to turn it up a lot to actually get something out of the outputs. Manual shift, CV and Mix don't do anything at all.
I didn't try the calibration procedure as it doesn't look to be solvable that way, but I can be wrong about that (wouldn't mind to be wrong to be honest :-) ).
