Hello, i've just finished my midibox today, and tried it. i'm just using one aim and the core with 20 knobs and have a problem, i can resolve. i've got a knob, wich give full of values without sense when i touch it, and some other wich give them right value, but send value in the channel of the first sick knob. i verrified the soldering on the ain, everything seemed to be correct, also on the knobs, is it possible that a wrong connection between a knob and the +5v or mass causes this kind of problem ? the non-used pin of j3 and j4 are connected to masse. i also check the voltage to all the pin of the knob, and it was correct, unfortunately i don't know how use a ohmmetter ! have you an idea to where i've got to search the problem?
