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.
