BLENDED BANDPASS

This is a manually controlled bandpass filter module. In addition to the normal controls for frequency and resonance, there is a control for blending the filter's output back in with it's input to give a finer degree of control over the sound. This is combined with a phase reversal switch for the filter's output which allows for notch-like outputs when combined with the blend control.

The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters.

Here is a youtube video that shows that demonstrates the module's capabilities.
