ADDAC, the french company is known for it's wide range of alternative ways to control synths...
I am a big fan of the concept of their 210 Open Heart Surgery module that they released already over a decade ago.
This one is inspired by Neil Young’s Whizzer (a box with servos that sat on top of his fender amp and allowed him to control the pots from his pedal board. ),
Using a Servo motor-controlled method they created a 4HP Eurorack module to control any knob that doesn’t have a CV input, while also possible to use for other gear as well (within certain distance constraints).
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.
Ranges can be set with 2 knobs [MAXIMUM ANGLE] & [MINIMUM ANGLE] further allow to control the “sweet spot” of the target knob, setting a smaller Servo range.
The module is compatible with most common potentiometers used in Eurorack: 6mm shaft’s potentiometers and tall trimmer potentiometers.
For pots using knobs they will need to be removed in order to attach the connection wire coupler.
Do not use this system with rotary switches, they will cause too much stress on the small motor!
