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 reactto the incoming signal. Controls bothattack and release.
Threshold - How sensitive the envelope is to theincoming signal.
Env Amt - Attenuverter that controls how muchthe envelope will affect the frequency ofthe filter, either negatively or positively.
Resonance - Synonomous with feedback or Q,this is a boost of the frequencies around thefrequency cutoff.
Freq - Also known as cutoff, this knob’sposition dictates the resting place of thefrequency cutoff.
LFO Rate - Make the LFO go faster or slowerwith this knob.
LFO Amt - How much the LFO will affect thefrequency cutoff.
Compression - End of chain compressor squashesthe wet signal to suppress unwanted honks, andresonant oddities.
Dry / Wet - Amount of unaffected vs. affected signalcoming through the output.
Sidechain - Direct input to the envelope follower.Normalled to the input, use this to have theenvelope follow an external source.
Exp Out - Output for the expression pedalinput. Exp isn’t connected to any controlinternally and must be patched.
- Env Out - Always sending +5V until theenvelope is triggered, bringing the voltagedown to 0V and back.
+ Env Out - Sends a CV signal following theenvelope. Signal is 0V to +5V.
LFO Out - Constantly sends the trianglewave 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 TRScable from any expression pedal into this, patchthe exp out to what you want to contol, andexpress yourself.
