A CV/Audio Mixer with Dual VCA. CV sections Blend has two CV sections each with: Input (normalled to a +5V signal) Attenuverter Output CV Mixer section Blend takes the outputs of the two CV sections and offers the following: Min output Max output Comparator output (level brought down to 4.5V) Sum output The min and max sections do not attempt to be precision min/max measurements. They will be within two diode drops of the actual min or max voltage. VCA Sections There are two VCA sections that are also have a mix output. The CV input for each VCA is normalled to the output of a CV section. The VCA circuits are LM13700 based so they will slightly color the sound. The response curve is nearly linear but offers a slight exponential curve. Power : 40 mA +12V 40 mA -12V 25 mm deep
