The Protostar is the evolution of the Super FatMan envelope filter with even more pro level features. Built in LFO, 4 filter modes, full CV patch bay, and expression/CB input, this is the most powerful/versatile envelope filter on the planet. Also includes an end of chain compressor and dry wet mix for parallel filtering/compression effects!



Attack – How fast the envelope will react to the incoming signal. Controls both attack and release.

Threshold – How sensitive the envelope is to the incoming signal.

Env Amt – Attenuverter that controls how much the envelope will affect the frequency of the filter, either negatively or positively.

Resonance – Synonomous with feedback or Q, this is a boost of the frequencies around the frequency cutoff.

Freq – Also known as cutoff, this knob’s position dictates the resting place of the frequency cutoff.

LFO Rate – Make the LFO go faster or slower with this knob.

LFO Amt – How much the LFO will affect the frequency cutoff.

Compression – End of chain compressor squashes the wet signal to suppress unwanted honks, and resonant oddities.

Dry / Wet – Amount of unaffected vs. affected signal coming through the output.

Sidechain – Direct input to the envelope follower. Normalled to the input, use this to have the envelope follow an external source.

Exp Out – Output for the expression pedal input. Exp isn’t connected to any control internally and must be patched.

– Env Out – Always sending +5V until the envelope is triggered, bringing the voltage down to 0V and back.

+ Env Out – Sends a CV signal following the envelope. Signal is 0V to +5V.

LFO Out – Constantly sends the triangle wave LFO CV signal, reacts to LFO rate knob.

LFO Rate – CV input for control over LFO rate. Sensitivity adjustable with internal trim pot.

LFO Amt – CV input for control over LFO amt.

Freq – CV Input for control over cutoff frequency.

Feedback – CV input for control over resonance.

Expression Input (back panel) – Plug a TRS cable from any expression pedal into this, patch the exp out to what you want to contol, and express yourself.
