EB Signal Control

Modular DC pocket knife

This is our attempt to make a little modular DC pocket knife. It a lot of features that you seek in modules, all combined into 12HP with a stunning led array for visual feedback. 

4 LFO’s each with 3 different ranges and frequency control that go up to VCO range. And 2 different waveforms, Triangle and Square wave.
A 4 channel DC mixer.
2 individual VCA’s.
A 2 channel inverted mixer, each channel controlled by a VCA. 
And 2 Sample & Holds circuits.

Each of the selected individual VCA's, Sample & Holds, LFO's or Individual inputs can be controlled by attenuators for positive and negative depth and or volume / amplitude.

And to top this of, all of these channels can be fed into 4 different differential rectifiers. This idea is large based on the incredible work of Andrew from Non Linear Circuits. “Basically the circuit compares the voltage on the ‘-‘ inputs with the voltages on the ‘+’ inputs. The difference between these voltages is fed to the outputs. If the difference is positive it appears on the ‘+’ output, if the difference is negative it appears on the ‘-‘ output. Again, a great way to mix boring CVs to get something interesting, audio frequency wave-shaping and it also can be used as a crude VCA.”
