“Maker of the most powerful and versatile envelope filter on Earth” is a tough claim to prove, but WMD does just that with the Protostar. This so-called harmonic density engine packs quite the list of features. It has a built-in LFO, four different filter modes, a full-featured CV patch bay, and an input jack for an expression pedal / CB. It even tightens up your tone with an onboard compressor section and extends your control further via a dry / wet mix knob.

    I use filters all the time, so I have an arsenal of them. Protostar is capable of virtually anything my other filters can. Sometimes even better. All its four modes sound fantastic. Overall, it’s a great piece of hardware.
