Winterbloom Neptune Diode Ladder Filter

This is a newly-built and tested reproduction, as the original manufacturer Winterbloom has closed up shop and is no longer producing this module.

Neptune is a resonant diode ladder filter designed in collaboration with Carson Walls. It's intended to bring together sound and modulation into a complete, distinct synthesizer voice. Unlike typical multi-mode filters with separate modes or outputs, Neptune instead has separate low-pass and high-pass inputs into a single filter core. It's coupled with a feedback-modulated distortion circuit called salt that opens up a wide range of tonal possibilities from tame to dirty to outright chaotic.

Neptune is not like its silky-smooth cousins- it's a wild, out of this world filter that exhibits delightfully strange behavior as you push its parameters to their limits.
