The ADDAC320 Servo Control is a Eurorack-style nod to Neil Young’s Whizzer, a tool that enabled control over amplifier pots through the use of pedals, resulting in far-reaching tonal variation.
Inspired by this methodology, ADDAC's Servo Control incorporates a Servo motor into a 4HP Eurorack module, enabling it to control any knob that doesn't have a CV input, or other gear such as guitar pedals - within certain distance constraints.
A servo is a specific type of motor that can be digitally controlled to work at precise angles.
On the ADDAC320, it is controlled by a microcontroller which is able to receive an incoming CV voltage from 0 to +5v and linearly converts this voltage range to the 270 degree Servo motor range. Using a spring wire and metal couplers, the motor shaft is then attached to the target knob to be controlled, which will turn as the Servo turns.
Two other knobs, Maximum Angle and Minimum Angle, allow further control of the “sweet spot” of the target knob, establishing a smaller Servo range.
