Scaling Buffers

From the original SMMS catalog:
”The SCALING BUFFER (BUFF) is useful for controlling two or more modules from the same control voltage. A single knob and an offset voltage allows a change in the settings and response of modules simultaneously. The pitch and tracking of two or more oscillators or filters (for example) can be changed without re-adjusting the individual processing inputs or frequency knobs for each module.”

Can be used with traditional wired builds for adding more control options to other DIY projects

** 4U Modular is a term used for the format most commonly known as “Serge Format” or “Loudest Warning Format”. Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and mounting hole style. 4U Modular will patch up just fine with other 4U "Serge" formats such as "Random Source", but it will not mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website soon to make this a lot more easy to understand.
