I'm just curious about a component that's on a board
in a synthesizer I have. It looks like a pot and it's
hooked to a knob that turns through about 315 degrees.

It could be a Hexadecimal or BCD-output rotary switch. See if you
get continuity in a binary-like sequence.
Hmm. This thing determines a MIDI controller value that varies between
0 and 127. Maybe it's doing 2 Hex digits and throwing away one bit?
But the resistances between the various leads do vary as I turn the knob;
they go up and then down in a non-linear and non-monotone way.
Probably an encoder then.
