user46743: I'm building a MIDI controller with the Arduino Micro, hooking a bunch of knobs up to the analog inputs. Currently, I'm getting analog in 9 being influenced by analog in 10: analogRead(9) returns a number close to analogRead(10) and doesn't give the voltage that I'm reading with a multimeter.
What could be causing this interference?

user46743: I looked around for a while and eventually thought to put the multimeter probe on the top pin instead of on the soldered header, and got no voltage across it.
If you're experiencing a strange interference between two analog inputs, double-check your solder joints again, one of your inputs might be floating (not connected to high or ground).
