Adds pitch CVs for ondes Martenot

Precision adder (low offset, high input impedance, low drift) for pitch CVs. Either keyboard or ribbon is selected; if keyboard, then keyboard shake is also added in. Four buffered outputs without 1k resistors.

Early conceptual design, now replaced by Offsets

• 20 mA +12V
• 20 mA -12V
• 0 mA 5V
• 40 mm Depth
