Passive Low Pass Gate

Introducing lpg : a passive low pass gate with vactrol design. In 4HP, this is a really useful tool for your eurorack system. Use it as a low pass gate by sending a cv signal to the cv input like a trigger / gate and modulate the audio signal that comes from the input to the output.

When a cv signal is plugged in, the red led behind the front panel will shine and let you see when it hits. Then, there is a knob that can change the color of the audio signal. If you turn it to the left side, you well get a low pass feature. If you turn it to the right, you will get the raw and bright signal input modulate by the cv, it’s a kind of VCA. If the knob is at noon, you well get a mix of this two features.

Note that, as it’s a passive module, there is a bit audio volume loss.
