Proton Envelope Filter

The Proton Envelope Filter by 3Leaf Audio is a modern homage to the classic Mutron III envelope filter. It features a wide frequency response that works well with various instruments. The version 3 of the Proton has increased input sensitivity to better accommodate low-output instruments. Additionally, it includes a tone knob for variable control over the filter cutoff frequency.
