Harmonic density engine

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!

Controls

KNOBS

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.
