Hello Dan,

another idea came to my mind: you can modify the characteristics of a
potentiometer by adding on one side of the potentiometer a paralleled
fixed resistor. There is a nice small application by christoffer list,
which explains this nicely
http://www.mindspring.com/~clist/PotGraph.html

You will get an quasi logarithmic behaviour if the parralleled resistor
is 5kOhm. This might affect also other characteristics of the overall
circuit (I cannot judge from here, since I have the Servicemanual at
home), but it won't damage the module.

Perhaps the A-142 is designed to extend the lengths of super short triggers where as mine are already slightly long gates. I can only shorten them by barely any threshhold settings with all pots at 0. CV to make the gates slightly longer must be done with the Cv pot barely above 0.

As soon as I get up a bit, the envelopes are a few minutes long and can't even imagine the lenghths at 6 o'clock. I don't see any jumpers to change the range levels but wonder if this is how it's made or if there's something wrong with mine.
