CHAPTER 7. CONTROL PANEL: HAVING COLORED ENDLESS ENCODERS INSTEAD OF POTENTIOMETERS.
When we at Crumar designed the Seven we had to make a choice: normal potentiometers or endless encoders? Since the Seven can
store and recall presets, we wanted to find a solution to the problem when potentiometers' physical positions do not reflect what has
been stored into presets. Since putting motorized potentiometers was completely out of the question, we came up with a very elegant
and practical solution: RGB illuminated encoders.
Since most of the knobs don't need to be set to a precise value, a numerical readout is unnecessary (even a potentiometer can't give a
precise readout), so the idea is to have the knob change color according to the current value, towards green when the value is low and
towards red when the value is high, with intermediate shades of colors in between.
